Do you still use traditional bamboo springboard in engineering project nowadays? Itâ??s old fashioned with lots of shortages. Now with the booming of various scaffolding accessories, it is no doubt that we would adopt new style product for engineering project. And steel springboard would be one of them.
The hot dip galvanizing process would become the mainstream among the method for the steel springboard in the future. The steel springboard having the treatment by hot dipped would be the main material for the springboard in the future.
As we all know that steel springboard has the following advantages:
1.CO2 shielding gas technology product, anti-corrosion and anti-rust would give a long life for those scaffolding accessories.
2.It is more stable with anti-skid design than bamboo material.
3.It has an indispensable safe platform for construction work acceleration.
Each kind of steel pipe, with different wall thickness unit, would have corresponding OD. Today, our main topic would be focus on seamless steel pipe-carbon steel pipe. The list would show the relationship of wall thickness and OD for it.
From the list above, we can get the following information. With the increase of OD, the range of wall thickness unit would be different. If the OD is below Φ42, then the large WT would be 5mm. And of course, if the OD is larger than Φ68-Φ73, the WT would have no 3.5mm. Under this situation, we should choose the right OD according to the corresponding WT.
Flanges used for steel pipeâ??s connection are various. So we should make our flanges lead to the purpose of our steel pipes like seamless or erw steel pipe. So we need to do some lesson before purchase.
Function of long weld neck flanges is predominantly on vessels. We know that vessels have some places need an extended neck so flange can do this job for us. The purpose of tapered neck is to reduce the thickness of the steel and it then seems to be a pipe extension. The combination of steel pipe and long weld neck flange would make the whole engineering project easy and convenient. Utilized in the chemical and petroleum industries, as well as commercial and residential buildings that experience high levels of stress and temperatures that fluctuate, flanges have played an important part during our daily life.

There are four types of 90elbows for connecting each kind of steel pipe.
These are 45elbows for connecting each kind of steel pipe.
Of course, there are some wonderful design for the connecting of each kind of special steel pipe.
If the hero of scaffolding system for your engineering projects never comes to you,
If you need some of them come to you,
Youre feeling blue and you are alone.
Then, scaffolding system from hunanworld will show you there is destiny,
The best things in life are having the scaffolding system from scaffolding pipe, ring lock system to plank. They would help us to solve lots of troubles which human beings cannot solve easily without the help of tool.
If you want to cry, crying on the scaffolding systems shoulder.
Who cares for you; who save your time for your; and who would be protect your too.
Weâ??ve talked about trestle and steel scaffolding system in last essay. Today, we would have a comparison for patented and suspended scaffolding system. No matter which kind of scaffolding system, original material would be necessary for security and each kind of guarantee.
Patented scaffolding system(the left one on the picture) is made from steel. Under this situation, they would have fitted with special couplings and frames which would make them guarantee the workerâ??s safety. And it is adjustable to the required demands for customers so that the workers can work conveniently.
For suspended scaffolding system(the right one on the picture) would be mainly used among paintings, repairs works. Our company would also call it scaffolding staircase for wholesale. With the movable design, it can be lifted or lowered to the desired level.
No matter which brand or material you finally choose for your scaffolding system product, you need to think about some main points. For example, the quality, the joint and so on. Today, we hunanworld scaffolding supplier would have an introduction for you.
Quality: material and production process would have direct impact for scaffolding systemâ??s quality. So we should choose high quality components which are engineered for strength and durability.
Joint: jointâ??s safety would make sure the safety of the workers. Under this situation, suppliers should make optimization for joints. For example, we can allow up joint to 8 horizontals and diagonals to be connected, which would offer incredible adaptability.
Versatility: versatile scaffolding system products would popular among each kind of engineering project. With complex shapes, elevations, and plans, they are ideal for structures building.
Convenient & Compact: how could we forget conveniene when we purchase this kind of product
Some of the safety parts come from the scaffolding system, and we just need to assemble them when we need them in construction process. Today, we will talk about other advantages for the mobile scaffolding one.
Thirdly, adequately spacious would be its advantage too. We can make workers free if we can make them feel stress-free. Under this situation, scaffolding system would one of the option to give workers safety. With the help of it, workers would have more space to move and set construction tools.
Some clients who enter steel pipeâ??s industry as freshmen so that they donâ??t know exactly about the categories. Today, as scaffolding pipe supplier, hunanworld would have a list for the categories identify for choosing scaffolding pipe. Under this situation, they can get to know them basically.
From the picture, we can figure out that there are several types for them:
1) Angle bar
2) I beam
3) Channel
4) Square tube
5) Round pipe
6) galvanized pipe
Under this situation, we can pick up the rightful one according to our projects features.
There are too many words to show who we are and what we do online. Today, we just want to tell you who we are and we we do from the picture below. You are right: we are scaffolding accessories supplier.
Scaffolding
We are serious on raw material choosing on raw material and quality control on products. Of course, this doesnâ??t mean that we have to serious for negotiation. We are cute salesman with our scaffolding accessories. Come to us and you would find happiness when you buy products.
Different scaffolding accessories would have its special characters. Thus, we should follow their features to make the rightful installation. We would highly recommend these tips for you before you need to install them by yourselves.
There are three main types of scaffolding system(of course, we supply more than these three types). They are Kwikstage, Cuplock and Ringlock. Their common feature is that they are prefabricated in nature. Thus, we should take the important factor of per manufacturerâ??s guidelines. This is important because the structural stability and the scaffolds load supporting capabilities depend on how the scaffold is installed. Whatâ??s more, we should follow the life insurance of the scaffolding system. Thus, we would make the better use of them from the installation.
Each kind of engineering project would count our safety in before the start. So does for the installation and work of scaffolding system and products. Today, we would like to share the .aying requirements of scaffolding steel pedal.
First of all, we should clear that the operating layer should be covered, paved, and solid.
What's more, construction of galvanized steel pedals (foot-boards, steel springboards) shall be provided on three horizontal horizontal bars. Attention! When the length of the scaffolding is less than 2m, two horizontal horizontal rods can be used for support, but the two ends of the scaffolding should be fixed with horizontal horizontal rods to prevent overturning.
Additional, the scaffolding should be laid with butt tiles or lap joints.
Generally speaking, scaffolding system product would have a long service time if we use them carefully and have a good maintenance habit. Today, we would share some basic common sense for all of us to know.
Adequate sill or pad would be necessary for the scaffold productâ??s installation. Under this situation, we can avoid the slipping or sinking trouble effectively. At the same time, we can fix the thereto.
Whatâ??s more, if you need to buy scaffold for any part of building or structure, we should firstly make sure that they can support the maximum intended for scaffolding product.
Additionally, adjusting screws must be used during the installation to keep safety.
Hunanworld scaffolding products goal is to create a secure global various projects of construction environment, efficient construction progress, and excellent customer experience, through scaffolding pipe, steel plank and scaffolding accessories.
Today, we shall have main topic over scaffolding accessories. And we will have stair case 860*1829*1955*2677mm for example.
From the picture above, we can see that there are two kinds of stair case with different size and hook. Under the comparison, customers would know which kind is better for their engineering project. More details, you can have a view in website or just contact us directly.
Once you climb the scaffolding accessories, you have to responsible for your own life. Thus, we should figure out the dos and donâ??ts during the whole working period. And this would be our discussion here.
First of all, please remember to check your base work before you climb your scaffolding accessories for your work. You should make 100% percent for the scaffold accessories are grounded and properly matches the structure. And donâ??t make the mistake that assuming the foundation is safe all the time as we cannot ignore the damage from deterioration due to climate.
In addition, please let us treat the scaffolding accessoriesâ?? loading-bearing capacity all the time. All tools would have a maximum amount for its bearing. It will just permit the upper limit of workforce and materials on a scaffold and no more. This is, perhaps, one of the greatest avoidable reasons for scaffold accidents. And thus, donâ??t overloading would be our main focus whenever and where for us.
No matter in construction or maintenance work, scaffolding accessories play an important role in convenience and safety. Today, we would talk about the safety tips for working with it.
First, safety would be number one role. Speed would be an important thinking factor when we use scaffolding accessories for work. If there is a greater emphasis laid on efficiency, safety isnt compromised.
Secondly, how could we ignore the workplace placement. We should avoid any slips and mishaps by keeping the work site organized and arranged.
In addition, identify the hazards would be necessary before starting. This should be done before working on the project and while performing the task. Make sure that possible risks are identified and proper care is taken so that it doesnt turn into an accident.

Carbon steel pipe can be used for thermal equipment, machinery industrial pipe, oil line pipe, geological drilling steel pipe, container steel pipe, chemical industry steel pipe, and other special purpose steel pipe.
Large-diameter welded pipe is the pipe welds, raw materials are mainly steel sheet and strip, large diameter straight seam welded steel pipe is used, the higher productivity of the kinds of steel, more used in more low-cost steel products one. Large diameter spiral welded steel pipe is used, compared to the straight pipe joints, mechanical strength of the products is relatively high, to save raw materials, but the production is slow. The product is widely used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, is one of the products of China's 20 key development. For the transport of liquids: water supply, drainage. For gas transportation: gas, steam, LPG. For structural purposes: as piling pipe for bridges; piers, roads, pipes and other building structures.
In the large-diameter steel pipe welding process, the most commonly used is welded steel pipe, which is mainly used for oil drilling and machinery manufacturing stove pipe can be used as water-gas pipe, large diameter welded pipe for high pressure gas transmission, etc.; spiral welded pipe for oil and gas, piles, piers, etc. seamless steel pipe and welded steel pipe is lower than cost, high production efficiency. Longitudinal simple production technology, high production efficiency, low cost, rapid development. spiral strength than the straight seam welded pipe is generally pipe, can narrow the billet production of large diameter pipe, you can use the same width of the billet production of different pipe diameters, but with a straight seam pipe compared to the same length, the weld length of 30 to 100%. and lower production rate, so the smaller diameter pipe is mostly a straight seam welded, large diameter spiral welded pipe is mostly used.
According to different methods can be divided into arc welding pipe, high or low frequency electric resistance welded pipe, gas pipe, stove pipe, Bundy tubes. According weld shape can be divided longitudinally and spirally welded pipe welded steel refers to steel or steel bending round, square, etc. and then welded into shape, the surface of the steel pipe seams welded steel pipe production process simple, high production efficiency, variety specifications, less capital equipment, but generally lower than the intensity of seamless steel tubes. since the 1930s, along with the rapid development of high-quality steel rolling production, and improve the welding and inspection technology, continuous improvement of weld quality, welded steel pipe increasing number of varieties and specifications, and in more and more areas instead of seamless pipe.

There is no doubt that we all know the big deal between chinese and usa recently. As supplier of erw steel pipe, we all know what does this mean. It also shows that there will be more and more high-level cooperation in the future of sino-u.S. Economic and trade cooperation.
According to threewaysteelpipe manufacturer for seamless steel pipe, erw steel pipe and other steel pipes, there are 34 cooperation projects in two signing ceremony, the amount reached 253.5 billion us dollars. It is really a big deal for each country. Of course, the industry is also very wide so there are lots of industries would benefit from this cooperation.
The contracted sectors cover areas such as energy and chemicals, agricultural products, aircraft and components, life sciences, environmental protection equipment and smart cities. The bulk of the contracts mainly focus on energy. As a large manufacturing country, china has a wide range of needs for various raw materials and energy sources and needs a diversified supply of energy from the u.S. Enterprises.
Cooling bed is a key link in steel pipe production line for guarantee the final quality. So there is essential to have some basic knowledge for those types of cooling bed for seamless steel pipe in order to produce high quality product.
Most of us would familiar with single chain cooling bed and double-stranded cooling bed, so there would ignore the introduction about these two types. And today the main core is the new chain cooling bed and stepping rack-type cooling bed.
The new chain cooling bed
No doubt that with the development of advanced technology, the new chain cooling bed has combined good feature of single and double cooling bed as well as other special characters which would good for the production of the steel pipes. New chain cooling bed has been divided into uphill and downhill. The positive and negative interaction make the steel pipe continue to rotate forward and do climbing which is good for quality. Downhill section for the forward transport chain and steel pipe parallel arrangement of single-chain structure, relying on self-weight to achieve rotation, so landslide movement.
Stepping rack-
type cooling bed
With two sets of step racks, there is no doubt that we can make the steel pipes safely and high quality except the basic demand requirement for steel pipes.
With the expansion of urbanization, there is no doubt that the requirement for various steel products, like the galvanized steel pipe would be increased among every kind of engineering project. Shopping for galvanized steel pipe from manufacturer would be increased too.
Galvanized steel pipe, with steel grade q195, q215, q235, q345, s235jr, s275jr, stk400, stk500 in threewaysteel, is for size of 21.3 - 610mm out diameter. All pipes have been hot dipped in a zinc rich galvanizing process. Of course, there are three types of the galvanized steel pipe including pre-painted (zinc: 60-120g/m2); hot-dipped galvanized steel pipe (zinc: 120-500g/m2) and cold-dipped galvanized steel pipe (zinc:10-50g/m2). Why it is an option for customers galvanized pipes are a lower cost alternative to stainless steel to achieve rust free protection once they have the helper of the zinc. Of course, maintaining comparable strength with a durable surface coating would be good for the corrosion resistance.
SSAW steel pipe, known as the submerged-arc welded helical pipe, is widely used in our daily life as well as engineering project.
Threewaysteel produces seamless steel pipe, welded pipe like ERW steel pipe, SSAW steel pipe and LSAW steel pipe which are used in various places nowadays. With large standard scope from API 5L, API 5CT, ASTM A252, ASTM 53, EN10217, EN10219, BS, JIS, IS, suppliers can basically meet the demand of clients, including square steel pipes, nickel alloys and more. All production would be meet customersâ?? exact size and certificate demands and is available for ship worldwide from a number of locations.
With steel pipeâ??s out diameter from 219.1 mm to 2540mm (8"-100") and wall thickness from 3.2mm to 25.4mm, we can see that there is no much problem for customers once you need the exact products as we can customized it for you. See website of threewaysteel for overview information. Please visit our product pages for availability and other information specific to each product.
As the saying goes that different strokes for different folks. So does for the choosing of pipes for residence and commercial places. We would like to choose the different pipes according to our taste, pipes function and other factors. For Sara, it would be a consideration for the steel pipe like the galvanized steel pipe.
However, which kind of material would you like to choose for your water pipe? Here are some sharing for all of friends. No matter hot or cold water, there is system generally conveying potable hot and cold water. They are applied in drinking water supply, cooking, and cleaning within in residential, commercial, institutional, and industrial buildings. There are several categories for pipes, such as copper pipe, CPVC pipe, galvanized steel pipe, PEX tubing, PVC pipe and stainless steel pipe. Each of them would have special power once you choose it. For example, copper is a long lasting, corrosion resistant, lightweight and strong material used in pipes making. However, we all know that we would decide the pipes option according to price, quality, function and other factors.

How could we forget the sulfate galvanized conversion when we talked about the process characters of galvanized steel pipe. Today, as manufacturer of steel pipes, Threewaysteel pipe company would have a list for sulfate galvanized conversion in hot galvanized steel pipe.
Sulfate galvanized conversion:
Sulfate galvanized ferroalloy retains only the main salt of zinc sulphate zinc sulfate, and the remaining components, such as aluminum sulfate, alum (potassium aluminum sulfate) can be added in the treatment. This would finally lead to the formation of insoluble hydroxide precipitate precipitation. For organic additives, we can add powdered activated carbon adsorption to remove it. Tests showed that aluminum sulfate and potassium aluminum sulfate is difficult to completely remove in once. And this has a certain degree influence for brightness for brightness of the coating, but it is not serious, as it can be taken out of consumption, which make coating brightness can be restored. The solution passed the treatment, according to the new Process ingredients required additional content, that is the final complete the conversion.Stripped Sunflower Seeds
Physics would tell us that degree of agitation have influence for galvanized steel pipe. Why? Here are some details introduction for it. And it would help us to slow the corrosion for steel pipe once we know the principles for damage of the steel pipe.
Once we put the galvanized steel pipe on water, high water velocity can lead the quick erosion corrosion. Thus, here are the troubles caused by scouring of metal surfaces by turbulent water and suspended solids that removes protective scale (12, pp. 2.15, 2.16, 2.25 ; 15, p. 7220). Under this situation, we should know that water movement would have influence for the damage of galvanized steel pipe. As it would lead water aeration to support corrosion. Quickly dissolved oxygen is normal would damage the surface of steel pipe.
As steel pipes supplier, even for ERW steel pipe, we can supply different types with different grade, certification for customers. Today, editor would have a detailed introduction for the physical parameters of ERW steel pipe JIS G3444.

Each kind of test measurement such as Technical Properties (Flattening Test, Bending Test, Blow Test, Impact Test), Exterior Size Inspection, Hydrostatic Test, X-ray Test would be necessary for guarantee of the high quality of steel pipe like seamless steel pipe, galvanized steel pipe.
There are some characteristics for visual inspection of non-destructive testing:
1.Weld surface defects test: surface cracks would be the first step for check of the steel pipe and then the impermeability and weld quality of the leak.
2.Detailed exam for raw material for steel pipes production, such as the surface cracks, peeling, cables, scratches, dents, bumps, spots, corrosion and other defects.
3.Cavity detection. This test would carry out according to the engineering projects demand and the engineers requirement.
4. Additional material inspection. Inspect the product for dust, foreign matter and other residues in the cavity.
Different steel pipe would have its special production method, so that they would have multifarious characters. Today, we would like to talk about black ERW steel pipe among welded steel pipe.
1)It is a kind of steel pipe made by hot-rolled coil through the molding machine;
2)Main production method would be high-frequency;
3)Compared with ordinary welding steel pipes production technology, black steel pipe has better technical on body melting, mechanical strength;
4)Black ERW steel pipe has features of smooth appearance, high precision, low cost welding seam height and so on.
One of my fIrrigationriends is doing business about watermelon in greenhouse. Under this situation, there is no doubt that he needs the help of various steel pipes from seamless steel pipe to ERW steel pipe and others steel pipes for the watermelonâ??s irrigation during the hot summer.
First of all, we should figure out the method for long distance transmission of water for the watermelon. Under this situation, he tries the way of long distance ERW steel pipe for this function. Generally speaking, seamless steel pipe is more expensive than ERW steel pipe, and it was just used for water supply. So ERW steel pipe is enough for this role.
Second, due to the large scale of watermelon irrigation, we would like to choose ERW steel pipe. Seamless steel pipe, because of its decided and small-bore diameter, is not suitable for this large scale irrigation.
In general, even for seamless steel pipe, we can make a list for different types of them due to wispy difference by different production process, adding original materials. Today, our main topic would be a special seamless steel pipe-bearing steel pipe.
The meaning of bearing is having a/some/no etc bearing on sth. According to the definition, we would know that as for bearing steel pipe, it has high smelting quality requirements, meanwhile, and requires strict control of sulfur, phosphorus, hydrogen content. Only this, can it does its immense pressure and friction job perfectly. What exact characters it should have? Steel hardness, wearing resistance, high elastic limit would be our consideration if we need to produce bearing steel pipe. So if you need seamless steel pipe and you donâ??t know which one to choose, welcome to have a discussion with us.
Steel pipes, no matter seamless or welded one, like erw steel pipe, are made by two different processes. It would involve four main steps for the perfect and high quality steel pipe.
First of all, choosing your end of pipes would be necessary. For the ends of pipes, there are 3 standard versions available, they are plain ends (pe); threaded ends (te); beveled ends (be).
Secondly, we should focus on length of pipes. Piping lengths from the factory are not exactly cut to length but are normally delivered as: single random length has a length of around 5-7 meter; double random length has a length of around 11-13 meter; shorter and longer lengths are available. However, for a calculation, it is wise to use this standard lengths; and other sizes are probably more expensive.
In addition, packing would be another topic. Packed in wooden crates, wrapped in plastic, and suitably protected for sea-worthly delivery or as requested.
Last, we should consider the delivery. Pipes are supplied in bundles or round bundles tied with steel strip. Of course, this would finally decided by customers.

Different types of steel pipe would be used for different engineering project. Therefore, before the installation of the seamless steel pipe or ERW steel pipe, we should have a research for the installation environment. Thus, we can choose the rightful steel pipe for the project.
Today, we would take line steel pipe for example to give customers explanation. Line pipe steels used in sour service are prone to hydrogen-induced cracking (HIC) depending on metallurgical and environmental factors. Thus, our first goal is to check the environment factors and decide the type of steel pipe. Whatâ??s more, the metallurgical factors consist of alloying elements, micro-structure, strength, segregation, and shape of non-metallic inclusions. Some environmental factors which influence HIC, also known as stepwise cracking (SWC). Thus, we should get well for the partial pressures and other factors like temperature, PH and so on. All of the research would lead you to the right steel pipeâ??s choice.
Actually, weve set special offer for our selling steel pipes in homepage. And their categories range from seamless steel pipe to welded one. And this essay would show you more details for these special offer tubes.
There are five kinds of steel pipes for special offer, they are:
ASTM A252 LSAW steel pipe: This kind of fluid transportation pipes mechanical & manufacture, steel structure, shipbuilding, bridging, and automobile chassis.
Rectangular / Square Tube: This kind of steel pipe made by plastic plugs in both ends, hexagonal bundles of max. 2,000kg with several steel strips, Two tags on each bundle, Wrapped in waterproof paper, PVC sleeve, and sackcloth with several steel strips
SMLS Steel Pipe BS 3059-2: This one would be used for carbon,alloy and austenitic stainless steel tubes with specified elevated temperature properties.
ASTM A179, ASTM A192, ASTM A210: It is used for wall panel, economizer, reheater, superheater and steam pipeline of boilers.
Alloy / Stainless Steel Pipe: Petroleum, chemical engineering, electricity, and boiler needs this tubes help.
Pipeline project, construction of transportation for oil, natural gas and so on, is now needed for improving peopleâ??s lifestyle. No matter ERW steel pipe or seamless type, customers would have different demands for the steel pipe. And comprehensive and strong would be one of the factors.
With modern science and technology, pipeline would have a wide applications. A number of general construction and installation works, professional engineering and construction, professional equipment and construction technology are needed for the guarantee of the high quality of comprehensive and strong. A pipeline as well as hundreds of tons of steel consuming millions of tons, and sometimes need to invest billions of dollars, a mammoth project is seen as a large, integrated industrial construction projects around the world.
API 5L line pipe, no matter seamless steel pipe or welded type, is now mainly used for conveying gas, water, and oil in the natural gas and oil industries. And thus we need to face some troubles for thinking all situations. High complexity would be one of them.
Oil and gas pipelines have features of long kilometers transport, complex terrain like climbing high mountains and crossing rivers, even passing through the marshes or dessert. Under this situation, we need to guarantee the long transmit for pipelines once we connect the tube with urban and rural construction. So we should produce the steel pipes which can adopt the situation of addressing a large number of temporary problems, such as supplies, transportation vehicles, roads, water, electricity, communications, construction, pipe prefabrication plant and livelihood security, all of which make the pipeline project is more complex.

HongKong-Zhuahai-Macao Bridge would be completed at the end of year 2017, according to recent news. Thanks to all of engineers as well as various materials like the steel products ERW steel pipe and seamless steel pipe, this huge bridge now is in our life.
Ive been here in Zhuhai at August, 2017 and Ive seen this huge and long bridge by myself. Which shocked me at that time. It is here crossing the whole sea and with all of original materials. I think the steel products appear would be the best answer for the complete of this huge bridge. First of all, we know that this long bridge has to hold on the weight of the long distance transportation, and all those steel products strength gives possibility for the strength of the bridge needs. Second, we know that there are lots of wind on the sea. And resistance of corrosion would be one of the most important role for the building of the whole bridge. And of course, galvanized steel products can provide this guarantee.
Thanks to the wise engineers and also the high quality steel products so that we can get the distance short between Hong Kong, Zhuhai and Macao.
Representing Threewaysteel pipe company, we are here saying Happy New Year to all of our friends and hoping a better wealth for all of you.

We are Threewaysteel pipe supplier which would provide you with various steel pipes whether you call for seamless steel pipe, ERW steel pipe, SSAW steel pipe, galvanized steel pipe or LSAW steel pipe.
As an export base, we are committed to provide professional one-stop procurement service for customers with excellent quality, competitive price, convenient transportation and timely delivery. With the high demand of requirement for ERW steel pipe recent years, there is no doubt that we can use them not only for water transportation, but also in oil and gas area. Thus, as ERW steel pipe supplier, we would adopt the advanced technology for production of the ERW steel pipe. For example, now we can supply various categories of ERW steel pipe for customers such as: ERW Steel Pipe EN10219, ERW Steel Pipe AS 1163, ERW steel pipe JIS G3444, ERW Alloy Steel Pipe,ERW Stainless Steel Pipe and so on.
One of clients asked if we can provide the sample of ERW steel pipe with standard DIN for him. Actually, it is our professional skilled producing these steel pipes nowadays. Today, we would like to introduce the standard DIN 2458 for ERW steel pipe in Threewaysteel.
With 25 year's cumulative experience of producing various steel pipes like seamless steel pipe, ERW steel pipe, galvanized steel pipe and SSAW steel pipe, we can say that we are proud in manufacturing these steel pipes. Of course, this also makes us offer a wide range of ERW steel pipe including standard API 5L, API 5CT, ASTM 53, EN10217, DIN 2458. IS 3589, JIS G3452, BS1387 and so on. It is produced by highly skilled and professional team members in Threewaysteel who have thorough knowledge of the prevailing industrial demands. You can see a big banquet once you entering the steel pipe's factory of Threewaysteel. For this DIN 2458 for ERW steel pipe, it is available in various specifications to provide a wider range of options to choose from.
Steel pipe market has improved in the new year of 2018. We can have an analysis from trading volume increasing and demand. It is obvious that we should have a new market plan for various steel pipes, such as seamless steel pipe, SSAW steel pipe too.
First of all, with the new year plas taking out, lots of engineering project would be here and thus the dominant orientation of large diameter straight welded pipe steel would be required. So that SSAW steel pipe would be here for customers.
Whatâ??s more, the steel trade business would be carry out in the whole world. Under this situation, there is no doubt that to improve the further development of large diameter thick wall welded steel market and other sizes of steel pipe would be another trend for the steel pipe market.
With new yearâ??s coming, new market goal would be carry out step by step and what we need to do is just follow our step of production and doing the best job for our clients.
As the saying goes that To be is to be perceived. You would feel it if we cannot describe it sometimes. This is for air, water, seamless steel pipe and so on. Even a child would tell his mother that we can use this tube for water when he plays games.
Seamless steel pipe, coming from Threewaysteel pipe company, with its special characters API 5L: GR B, X42, X46, X56, X60, X65, X70, is here for customers. We cannot see deep seaâ??s oil drilling all the time. However, as my child said that I know we need steel pipe when I have a shower and I need to have the steel pipe when I wash my clothes. We will know its importance in our daily life once the broken steel pipe cannot do any transportation work for us. We may not talk about them all the time, however, we know they are here with us which would give us comfort.
There are some special sectors for engineering projects need erw steel pipe largely. For this point, manufacturer threewaysteel pipe company would have a list for the relative steel pipe produced for customers.

No matter which kind of steel pipe, seamless steel pipe, or ERW steel pipe, or straight seamless welded pipe, there is the pipe forming demands for them in order to have the best quality when they applied in various engineering project.
Here is the list for welded steel pipeâ??s joint surface demands for manufacture and this would lead customers to figure out the better steel pipe too.
1.It is not allowed for cracks, pores, slag, lack of fusion, spatter during the production process.
2.Temperature would be controlled strictly. For example, we should figure out the different temperature for surface treatment about Fusion bond Epoxy coating, Coal Tar Epoxy, 3PE, Vanish Coating during the whole production.
3.It is necessary to notice that we should keep the whole temperature must not be lower than the surface of the weld surface of the pipe. For example, some of the welding reinforcement does not exceed 3mm (the maximum width of the weld after the groove).
We have to pay high attention to every step during the production process in order to have high quality steel pipes for customers.
The answer is definitely for good life of human beings when we get steel pipe from suppliers, whether it is seamless steel pipe, welded steel pipe or galvanized steel pipe. Without steel pipe, life would be horrible nowadays.
Different steel pipe would have speciality for its special characters. Here is the pipe introduction of SMLS steel pipe which belongs to seamless steel pipe.
There are six main categories for SMLS steel pipe: Fluid pipe, line pipe, structural pipe, high-pressure boiler pipe, low and medium pressure boiler pipe, casing and tubing pipe. Their difference is here in the list and you can see clearly. You can contact us once you choose the one you needed and of course, plz tell us once you have any questions with the list here.
On the morning of April 10, Chinese President Xi was invited to attend the opening ceremony of boao Asia BBS 2018 annual conference. As steel pipe supplier, from seamless steel pipe to SSAW steel pipe, weâ??ve learned lots from the keywords President Xi said.
Keyword--new age, new mission
We Chinese will continue keep the spirit of constantly strive to become stronger, and become better.
We Chinese will continue keep the spirit of innovation and pushing the development.
We Chinese will continue to keep the expand open, and highlight the cooperation.
As supplier of steel pipes and we have done import business for almost 25 years and it is time for us to follow the step of president to figure out the right way for us to get.
Cooling method plays an important role during the production process of seamless steel pipe. As some defects may happen during the cooling process if we donâ??t take the rightful plans for it. So we should have a clear understanding for the cooling methods before the production of steel pipe.
There are three main categories for cooling method:
1.Air cooling: according to the literal meaning, we can know the method easily. It is a kind of natural cooling method as we just need to put the steel pipe into the air. To some extent, it is a widely used way to cool steel pipe after hot rolling.
2.Fast cooling: this is the cooling method with the process of blowing, spraying and water. We can use fast cooling if we are in need of fast done for the product. Depend on the cold water, we can lower the temperature quickly than air cooling method.
Steel pipe, to some extent, is our most pal in our daily life. I wan to say that no matter ERW steel pipe or other welded steel pipes are our best friend nowadays. We need them almost like we need to breath every moment.
We would use Spiral Submerged- Arc Welded Steel Pipe for our low pressure liquid delivery, such as water, gas and oil during the whole day. Thus, we can make sure the regular supply for the necessary products for human beings. We would use seamless steel pipe for our high pressure liquid transportation, such as oil and gas for industries need. Under this situation, there is the products from the line for our better life than ever. We cannot leave steel pipes nowadays with its rising importance for human beings life.
Some clients would lets us to have an introduction for sour environments steel pipe. We would recommend line steel pipe no matter API 5L or other seamless or stainless steel pipe.
Today, we will have a general ideas for the introduction for steel pipes.
First of all, like we all know that, seamless steel pipe would be adopted in high pressure demand environment. Under this situation, they would be applied in gas, oil and other flammable products no matter fluid or solid.
In addition, for sewage water, there is impurity in here. Under this situation, large diameter steel pipe would be necessary. So the first choice for us here is the SSAW steel pipe.
And for sour environment, we would recommend line pipe as the title said.
More details, welcome the discussion through email or phone call with us.
According to the purchasing data, weve made an analysis for the hot steel pipes. Thus, we can provide you, our customers more concise service with ERW steel pipe, LSAW steel pipe and so on.
Weve added a new column for steel pipe, which is stainless steel pipe. They can be divided into seamless and ERW two types. Under this situation, it is our customers choice for which kind of steel pipe is needed for their engineering project. According to the recent wholesale situation, we know lots of pipe fittings are very popular. Under this situation, weve added the categories for this kind of produce. You can choose the suitable one for your project.
Of course, more information, you can contact us for details.
Except the high pressure steel pipe, we also get the abrasion resistant steel pipe which concludes seamless steel pipe for customers. Today, we would like to have an introduction for the usage and maintenance for abrasion resistant steel pipe
For the usage, we should know that the current commonly used wear-resistant pipe is to rely on a layer of composite wear-resistant materials to improve the life of the pipeline. And this situation, we will know it would benefits for the protection of goods as well as steel pipes.
Secondly, when talked about maintenance, we should know that although the hardness of the composite layer is large, but often very brittle, especially ceramic wear-resistant tube. Thus, we should make protect methods for it. For example, we can make control the factors we can control. During the transportation, maintenance process should be strictly prohibited to fall, knock, hit, to avoid the composite layer and the base of the separation.
Even for stainless steel pipe, they have different standards which mean they would have different function too. Today, we would have a basic introduction for the different standard and description for stainless steel pipe.
We can figure out that different standard would have different function for stainless steel pipe.
If you need seamless and welded one, you may need the astm a312/a312m.
If you need steel pipe for high temperature, astm a358/a358m maybe your better choice.
If you need large diameter steel pipe, astm a409/a409m could be your consideration.
More details you can have a view in the list. You can call us immediately if you have any trouble over the choosing of steel pipe.
Weâ??ve listed three main types of steel pipe for customers in last essay. They are standard pipe which contains seamless steel pipe and welded pipeline; line pipe and Oil Country Tubular Goods. Today, we will show friends another three categories of it.
Pressure Tubing: Used among industrial and pressure application, pressure tubing are produced using seamless manufacturing.
Mechanical tubing: Used for mechanical and structural application and is produced by ERW and seamless manufacturing. They conform to ASTM specification.
Structural Tubing: Used for support or retention purpose. This tubing can be round or square and are produced by ERW manufacturing. They are used for fences, construction and other misc. support needs.
Happy new year! This is the best wishes coming from threewaysteel pipe company, that specialized in seamless steel pipe, ERW steel pipe, SSAW steel pipe and LSAW steel pipe.
In this new year, threewaysteel has two topics here today.
First of all, wish all of you a happy new year. No matter what kind of things youve been through in 2017, now we can move it and welcome the new years coming. Wishing all of you a happy new year, good health, money and treasures will be plentiful.
Secondly, thank you all the way with threewaysteel company. We are a world-class SSAW steel pipe provider, one of the largest subsidiary in Shinestar Holdings Group Co.,ltd. As the companys largest export base, we are committed to provide professional one-stop procurement service for customers with excellent quality, competitive price, convenient transportation and timely delivery. And this is all of your efforts for your support and trust! Thank you and happy new year again!
Installation would be an important part among the steel pipes production and selling. As ERW steel pipe supplier or lsaw steel pipes manufacturer, it is necessary to make sure the easy installation between the joint of every steel pipe.
Troubles we need to pay attention:
A: The pipe ring trouble: we should guarantee it must be stiff enough during the bury to hold pipe rings shape to near circular.
B: Thick walls to provide equivalent stiffness is also quite important for various steel pipes. Due to the pressure steel pipes holding during the transportation, so in order to make sure the holding pressure, thick walls are necessary not only internal fluid pressure but also external pressure coming from cars and other products.
How to increase the ring stiffness for installation There are lots of options available. We can do this job from longitudinal strength and smooth outer surface. Thus we can solve these troubles and let steel pipes have relative character to hold on the products they transport.
News tell us that egypt is a modest exporter of natural gas transported by seamless steel pipe, galvanized steel pipe and so on, both through shipments of liquefied natural gas by sea and via pipeline to neighboring israel, jordan, syria, and lebanon. What, s the situation for chinese, s lng use and transportation?
China's pipeline gas is mainly shipped from the west to the country, while lng receiving stations are built on the sea due to the high cost of pipeline gas crossing the oceans and the ever-decreasing cost of shipping lng and the increasing demand for clean energy from the developed coastal economies in the prc. Lng in the past few years makes rapid development in china. No matter which kind of gas we need to be used for our daily life, there is no doubt that we cannot leave the pipes behind for its transportation function. For example, domestic imports of natural gas mainly come from three parallel pipelines (starting in 2009) across turkmenistan, kazakhstan and uzbekistan, with an annual capacity of 55 billion cubic meters and an annual supply of 12 billion cubic meters of shwe pipeline in myanmar (13 years operation). This data tells us that high quality steel pipe is needed here.
A confession coming from SSAW steel pipe touches me deeply. She said that she was afraid of being rejected due to the short-back of my unstable of pressure taking like the seamless steel pipe and so on.
As your friend, I would like to say that thank you. Without you, our life would not be so easy and colorful. With your various categories of different grades like S235JRH / S275JOH/S275J2H /S355JOH/ S355J2H and so on, you have brought us more convenience when we need you to do the transportation work for water, oil and gas in not only the hot day but also the cold day.
It is you suffered the pain of Chemical Component Analysis, Mechanical Properties (Ultimate tensile strength, Yield strength, Elongation), Technical Properties (Flattening Test, Bending Test and came around us and serviced us. We would give our gratitude for you.
Some customers would ask which kind of end we can provide so that they can make sure the pipe connection after they purchase. Actually, no matter seamless steel pipe or ERW steel pipe, there are different methods to connect. Here are some examples for showing you.
Generally speaking, there are following pipe connection: Butt weld, Flanged all types, Threaded, Socket weld, Glued, Brazed and Grooved end.
From the picture above, we can see that from the left to right, from up to down, they are Butt weld; Flanged all types; Threaded, Socket weld, Glued, Brazed and Grooved end. With these four types, there is no much big trouble for the pipeâ??s connection.
This article is wrote for those customers who are not so sure for which kind of steel pipe they need. As a fresh man in steel pipe industry, some clients would ask our advice for seamless steel pipe, stainless steel pipe or other steel pipe.
Today, we would make an outline for you and you can have a basic information for it. From the list above, we can get basic idea for the steel pipeâ??s choosing direction:
There are five main categories for steel pipe in Threewaysteel:
1. Seamless steel pipe (carbon, steel pipe, stainless steel pipe, alloy steel pipe);
2. ERW steel pipe (carbon, steel pipe, stainless steel pipe, alloy steel pipe, SHS/RHS steel pipe, galvanized steel pipe);
3. LSAW steel pipe ( structural steel pipe, fluid transportation pipes, external anticorrosive coating, internal anticorrosive coating );
4. SSAW steel pipe (structural steel pipe, fluid transportation pipes);
5. Pipe fittings.
In general, according to the different production process, we can category the welded steel pipe into several types. They are general welded steel pipe, like we said ERW steel pipe and so on; galvanized ERW steel pipe which is so familiar with us; oxygen welded tube which is not so common and so on.
General welded steel pipe would use mild steel as raw material. Material would determine its function. So this kind of steel pipe can be used in low pressure fluid after the water pressure test, bending and other tests.
Galvanized steel pipe would be a kind of steel pipe used for enhancing the corrosion resistance. It would be divide into hot dip galvanized pipe with thicken zinc layer and electrical-galvanized pipe with low cost.
And for metric system welded tube and spiral welded tube, we would talk next time. You can contact us for details about them.
A kind of steel pipe, no matter seamless or ERW steel pipe, would have its relative price with the corresponding price. So as steel pipe supplier, we would ask which kind of demand youâ??ve made for your steel pipe firstly, then we will discuss the details for our wholesale.
Steel pipe varieties, usages, piercing methods would lead to different final products for our customers. Here are some examples for you to understand.
Different purposes would have various choices. For general purpose steel pipe, we would have relaxed quality demand during the whole production. And the requirements would be strictly if you need them to use among important applications like oil and gas transmission. As the latter would concern about the stress condition, deformation perforation method and so on.
In short, steel pipe technical condition is to ensure the quality and smooth production process as the basis to determine, and with different methods vary perforation, with the technical conditions of steel to improve and increase. Technical conditions can be found on a variety of tube standards and technical protocols.
Abu Dhabi International Petroleum Exhibition & Conference this year has entered the terminal stage today. And we have showed our ERW steel pipe and other pipelines for customers here.
Time of Abu Dhabi exhibition: 12-15 November 2018.
Abu Dhabi exhibition booth no.: Booth No.10350 (Threeway Steel Co., Ltd).

More information, having a look at the website for details.
As the saying goes that Good tools are essential things. With the blossom of engineering project, there is no doubt that lots of clients would fall in love with various scaffolding accessories, like stair case, one client told editor Sara.
This kind of stair case coming from hunanworld, has the advantage of:
First of all, advanced CO2 shielding gas welding designï¼?assuring construction safety.
Whatâ??s more, standard step ladder is a necessary & fast construction equipment for scaffolding structure.
Of course, well drainage and anti-skip step would give guarantee for a safe platform work.
And, in addition, energy-saving and environment-friendly would give benefits when we think about purchasing.
When we need this kind of stair case, we would find that it plays an important role in our daily life.
Talking about the installation method, we cannot ignore the bracing, leveling and plumbing for the scaffolding system products. Today, we can have a detailed introduction for it.
First of all, during the erection process, we should make the steps are right. For example, it is essential to remember that we cannot force frames or braces to fit. We need to find out the right level and fit it until they can be fit easily.
Whatâ??s more, braced by horizontal bracing, cross bracing, diagonal bracing or any combination would be necessary. Under this situation, we can make sure the vertical members together laterally for each frame and panel.
of course, finally, we should follow the guidance book for installation.
One of our clients asked us to have an introduction for the scaffolding system of ladder before their final decision of purchase. Actually, it would more than three days for explanation. Today, we will have a general description by picture.
From the picture above, we will figure out the first step: which kind of type is your consideration?
First one is the base pack product. It would be okay if your engineering project is low and you just need a ladder for convenience. You should take more safety into consideration if your project has a high level. Under this situation, base pack and guardrail pack needs to be thought during the purchase. Of course, with more higher lever, extension pack is necessary like the picture showing for us.
If you need to buy scaffolding accessories, and you dont know which one is your choice, you may be need to see this article. And there are some categories of them for your choice. Of course, you can even email us for discussion and we can give you some advice for it.
There is just an example for the list of scaffolding accessories. We would like to make comparison or list the similar products for our customers to choose. Moreover, if you still have question on choice, we would make a meeting together online or offline for the final decision. Right tools of scaffolding accessories would make work fast and better.

Weâ??ve discussed about ASTM A53 series steel pipe with one of our clients recently. We told him that no matter ERW or seamless steel pipe, ASTM A53 series have relative one for customers.
Here are four types of ASTM A53 series steel pipe in Threewaysteel:
ASTM A53 LSAW steel pipe:
Process: LSAW - UO(UOE), RB(RBE), JCO(JCOE, COE); DSAW - Double Submerged Arc Welded
Usage: Used for low pressure liquid delivery, such as water, gas, and oil.

Standard: ASTM A53,ASTM A178,ASTM A500,ASTM A501,ASTM A691,ASTM A1020,ASTM A252,ASTM A672,EN 10219
Seamless Steel Pipe - ASTM A53:
From the outline, we can figure out that ASTM A53 contains steel pipeâ??s type ranging from LSAW, SSAW, ERW and seamless. So we need to consider the rightful one before wholesale.
Standard:EN 10210-1:2006 Hot finished structural hollow sections of non-alloy and fine grain steels.
Uses:For Building Structure.
Chemical Composition(%):
Weâ??ve updated our price list about SSAW steel pipe yesterday. And you can see details on our website. Today, weâ??d like to make a short analysis about the price discount here.
First of all, there is a real discount over the price for all kinds of SSAW steel pipe. For example, each type of this pipeline has reduced the price over 26 dollars/ton, some of them may reach 40 dollars/ton. Thus, we can get more high quality steel tubes for our engineering project. Secondly, it would be the cut price after half a year due to the lunar happy new yearâ??s coming in China. And it would be a good opportunity to save money. For more details about the price, you can check on the website or ask us directly.
It is not a joke when you see the title here. We will consider the appearance when we choose boyfriend or girlfriend, so does for the customers. They will choose seamless steel pipe or welded pipe like ERW steel pipe from aesthetic perspective.
How? And whatâ??s the standard for this choice? Here are the answers.
If you are considering wholesale pipelines which are exposed or featured in some way, most of customers would choose seamless steel pipe directly. Its clean and finished look would be the determine factor.
If you just want to purchase pipeline which is remain permanently hidden in the walls of a building or underground, there is no need to pay high price to get seamless type, and welded pipes would obviously be perfectly acceptable.
Each kind of product has its special character for good work. And so does for the scaffolding system steel springboard. Today we would have a topic for why does the steel springboard punch.
First of all, there are holes with the same size and shape on the surface of the steel springboard. And the flanges protrude is 3mm upwards, which can play a non-slip effect and play a role in the leakage of rainwater and sediment.
Then, the bottom of both ends of the steel springboard is embedded with ribs, increasing the strength, reducing the impact, preventing the sliding of the springboard on the steel pipe, and improving the safety performance.
Of course, the steel springboard is made of high-strength galvanized steel and has a good anti-corrosion effect.
-Where we steel pipe are?
-We are everywhere. We seamless steel pipe, stainless steel pipe, ERW steel pipe and so on are brothers and sisters in the whole world serving our loved masters.
Today, we would like to talk about steel pipe families who are working on fertilizer industry and petrochemical industry.
Fertilizer industry: the areas of application in fertilizer industry would mainly conclude in following aspect. We will know that urea synthesis ethylene plants melamine plants need high-pressure steel pipes and piping systems apparatus and so on.
Chemical and petrochemical industry: for this kind of industry, it may adopt the similar characters of steel pipe for their work, like piping systemsapparatus and heat exchangers are same.
One day, property management of residence told us that there is a house reconstruction for the water pipe as well as the gas pipe. In order to keep the safety of living people, changing for ERW steel pipe or seamless steel pipe for residents are necessary.
No doubt that construction in living house area would be a big engineering project and it is one of the most important steel pipes using area too. Not only for buildings, like houses to car parks building, but also various pipes changing with ERW steel pipes or seamless steel pipes, all of these projects would go on with the help of steel pipes for their strength and safety insurance for people. Whats more, we can even finish our roofs and cladding for exterior walls with steel or steel pipes.
We know why we chose seamless steel pipes for our water pipes as plastic pipes would explode in winter due to expansion and contraction. And the strength of steel pipes would give more balance for water treasure which is a top choice for customers too.
Weâ??ve got a car maintenance these days and the master said that weâ??ve got high quality equipment for our car so that even for the exhaust steel pipe is also nice for use. Under this situation, no matter which kind of steel pipe from seamless steel pipe to welded steel pipe, we should choose the cost-effective one.
There are two main reason for the high quality of the car, the master said. First of all, from the carâ??s aspect. We can see that even it was made in 2007 and it still good. This because the high quality material made of this car. Another reason is that the driver has a good habit for taking care of his car. Under this situation, there is no doubt that except for the good care for this car, we should notice that due to the high quality of the car itself. So even just a steel pipe, we should pay high attention to a car during the production process.
One of the friends told me yesterday that it was embarrassed when the ring lock system is short for the work. Under this situation, their boss had to buy another scaffolding accessories for office use.
Due to this situation, it is necessary to have a good lesson of standard and vertical for the one you need to purchase.
Here is the list for the ring lock systems characters and it would give you hel p. You can find the right purchase plan according to details.
Weâ??ve used four articles to list the characters for the API casing couplings. Today, we shall share the fifth one-non upset end (NUE). It would be good by using among steel pipeâ??s work no matter seamless steel pipe or stainless steel pipe.
You can tell that it is may similar with external upset end (EUE) from the aspect of types, size and OD. In general, they have difference too. We would make a lesson before the purchase of these five API casing couplings and use them in the right place.
Welded steel pipe would be a huge category among steel pipes. And for ERW steel pipe, it is small branch in welded steel tubes. Today, we would like to discuss the general type tube.
General means common. So for common welded steel tube, we can say that mild steel would be its raw materials. And this kind of steel tube is mainly used for the transmission of low pressure goods such as water with ERW steel pipe, sewage goods by SSAW steel pipe. Even so, these pipes need tests like water pressure and bending too. Of course, surface quality should be guaranteed too. And talked about characters for this kind of steel pipe, we can say that the length of delivery is often from 4 to 10mm. The specifications of welded pipe in nominal diameter are different from actual size. Depending on the wall thickness, welded pipe are also divided into common steel pipe and thicken steel pipe.
Coated steel pipe would have a good resistance for corrosion during the whole transmission process. And for ERW steel pipe, there are some benefits once we apply coating on it too.
The basic function of ERW steel pipe would have two main aspects:
It would be a good helper for ERW steel pipelines as the coating will make the surface of tubes away from electro-chemical corrosion of soil medium, the basic physics of bacterial corrosion protection.
Then, it would have good performance for resisting on various stresses. Such as resisting the move of the soil medium creep stress, static stress and abrasion force method and structure of the basic machinery protection.
There is popularity for coating feature once we wholesale steel pipes like seamless and ERW steel pipe. Why? Which kind of benefit would finally lead to the purchase for this kind of pipeline?
First of all, we should figure out that coated tubes can give us high resistance to corrosion for pipelines used among industries.
Then, coating would increase flow capacity by providing a smoother surface.
In addition, the pipeline coating increases the pipes durability so they can be deployed with minimum maintenance cost even in the harshest environments.
According to relative research, tubes are internally coated use less energy for pumping and compression.
The inhibitors used for the protection products can also be minimized by the use of coated pipes for delivery of products.
Steel pipes, no matter seamless or ERW steel pipe, play an important role in national economic development nowadays. Due to the different production process and original materialsâ?? various, there are large -diameter tube seamless, straight seam steel pipe, spiral welded pipe and so on.
Then, whatâ??s the trend for future steel pipe? I think the answer would be we would need more steel pipes among our daily life, ranging from each kind of industry like household, fluid transportation, oil and gas transmission, of course, marine need is also necessary. No matter which kind of steel pipe, it is accompanied by the development of technology and seamless and progressive. Steel pipe in some areas will be seamless to gradually replace the inevitable trend, the key factor is the continuous improvement of product quality and lower manufacturing costs. With the high speed development of high technology, we can improve the quality for both seamless and welded steel pipe in order to make a better life standard for human beings.
Even the price of seamless steel pipe is higher than similar ERW steel pipe, we still figure out the trouble with it. Today, weâ??ll see the defects of it and find out the reasons so that we can avoid it during our usage period.
First of all, abscission would be the most superficial one as we can see by our eyes. There would be spiral separation in steel pipeâ??s inner surface. Due to the poor non-metallic inclusions, residual shrinkage of the material, we get the trouble. Thus, we need to figure out the characters of the medium needed to transport. Finally, we will choose the suitable steel pipe for it.
In addition, fold in the steel pipe. A symmetrical or single linear folded sometimes in the steel pipeâ??s inner surface. Due to the poor lubrication of the mandrel, we may see this trouble during the use. Thus, we should pay high attention to the productâ??s production process.
Other troubles, such as wall contraction, rolling scars, may also here. Thus, we should pick up the master to make the steel pipe for our engineering project.

The convenience and high quality would be significant factor in our decision to which kind of pipes, from seamless steel pipe, welded steel pipe like ERW steel pipe, to choose from.
When we live in outskirt, humble room is a common annoyance of life in suburbia. It would make us feel fine if we just for travel. However, there is a big trouble if we live here for a long time. With the deficiency of the steel pipe for water transportation, we have to get them by tub. This would be very bad experience for us. Under this situation, if our master granted us a small ingot of steel pipe for transportation tool, we would be cheer up. From this story, we can find that productivity needs to be increased and happiness would be here too.
As the saying goes that you get what you pay for. So does for ERW steel pipe and other tubes. For superior quality pipeline, you will see their special features during the whole engineering project.
Special features of superior quality ERW pipes and tubes
High strength corrosion resistance: ERW pipes are cost effective pipes with tighter dimensional tolerances and less weight.
High malleability: ERW pipes find their usage in distinct fields.
Durable and sturdy: Processed through multifarious tests which will guarantee its durability and sturdy.
Different price would get various steel pipes with different features and for transportation of each kind of good, it is necessary to have high quality steel pipelines.
Fish cannot live without water. To some extent, we may not so convenient without the existence of steel pipes in our daily life. As ERW steel pipe would provide us water and seamless tube gives us oil and gas to industrial engineering project.
We canâ??t imagine a world without steel pipe. In the hospital, the patient canâ??t receive treatment in time because there is no needle tube. A lot of people are on the verge of death. At home, after a dayâ??s hard working or exercising, people canâ??t take comfortable shower. Most of the car comprise steel pipe, such as motorcycle, electric car and so on. Without steel pipe, we canâ??t use these cars. It is very inconvenient for us when we want to go out. Without the steel pipe, the natural gas and oil canâ??t been transported the place where need them. Consequently, natural gas and oil are over in some places, but in other places they are sufficient. People feel that their world has changed totally without the steel pipe. The steel pipe play an important role in their daily life.
ASTM A53, one of the ERW steel pipe, is mainly used among low pressure liquid delivery, such as water, gas, and oil. Of course, oil drilling and machinery manufacturing can adopt it too. Recently, one of clients had purchased 20 metric tons for it.
