Spiral welded pipe(SSAW pipe, also called HSAW pipe). The pipe is formed by spiral submerged arc welding technology. Spiral welded pipes are formed using narrower plates or hot rolled coils, which lowers their production costs significantly. The welding line shape like a helix. The spiral welding process permits the production of large-diameter pipes suitable for transporting large volumes of oil and gas. Some SSAW pipes were historically limited to low-pressure applications.
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.

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). Weâ??ve got lot not just for steel pipe business but also the advanced technology for tubeâ??s production. Good quality would be main core competitiveness for the enterprise. For example, our main products are carbon steel seamless pipe, carbon steel welded pipe, stainless steel pipe, pipe fittings and so on. How could we control the relationship with our customers? Talking and connection is just one aspect, providing high quality product would be the main reason for the long relationship.
Since the birth of ship, there is the helper of steel tube. With the coming of seamless steel pipe for oil and gas transmission, ERW pipeline for other functions during the normal operation for a ship, we can see the importance of steel pipe for ship service. Where is the position for steel pipe in a ship? Bilge water, ballast, air, sewage, measurement, fire, cargo oil stripping and so on, all of these locations need the help of various kinds of steel pipelines from seamless to welded steel tube. For example, special ships also include a dedicated system for the transportation of liquefied petroleum gas (LPG), liquefied natural gas (LNG). Under this situation, we will figure out that the shipbuilding industry has become a big user of steel pipe market.
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.
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.
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.

Welded steel pipe, like common ERW steel pipe, cannot ignore the trouble about cutting. And this is an essential step for the whole tubeâ??s production process. For manufacturers, they have to pay attention to that as a poor cut can lead to poor fit-up steel pipe. What effects are when there is poor cut. In general, a poor cut can lead to poor fit-up and create unnecessary gaps. More over, for some special steel tube, like stainless steel pipe with corrosion-resistant pipe, this would lead to distortion which may affect the corrosion-resistant quality. Of course, poor preparation also leads to longer weld cycle times, higher consumable costs and potential repairs. Thus, it would have influence for a pipeâ??s quality. How to solve this trouble for welders? A necessary cutting equipment would be the first step. For example, buying dedicated orbital pipe cutting equipment to guarantee cuts within mere thousandths of an inch of the specified parameters maybe one of the steps. Of course, the skilled experience for welder is also important.
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.
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.
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.
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.
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.
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.
