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.
We absorbed the international advanced technology of tube making, like FFX and cage forming flexible formation technology etc, which apply CAD system to deformation process of welding pipe, which analysis and research the distortion craft of high grade steel pipe, also coordinated with high-performance welding machine to solve better the forming and welding defects that provide the high grade & high value-added welded pipe products for users.
In the process of manufacturing square pipes, rectangle pipes with direct shaping and molding technology, combined type rollers are used with pieces structure. Roller sleeves are filled between roller pieces. The pieces structure is used for rollers. In the deformation region, rollers contact strip steel partially not fully, reducing the contact area and reducing the friction between strip steel and rollers accordingly.
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.

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.
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.
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.
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.
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.
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.
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.
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.

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.
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.
