Introduction and development of welded black iron steel pipe

Do you know what is welded steel pipe? Actually, when it comes to welding pipe, we usually refer to a kind of steel pipe with a surface seam formed by bending a steel strip or steel plate into a round or square shape. One thing that makes welded steel tubes different from other processes is that they are made of steel plates or strips of steel. It adopts arc welding tube, high-frequency or low-frequency resistance welding tube. Of course, different welding methods can form different steel pipe types. Setting welded steel pipe as an example, we can find that the welding shape is divided into straight seam welding and spiral welding. For straight seam welded steel pipe, its production process is simple and production efficiency is quite high, which has been favored by Tianjin steel pipe manufacturers. However, do you know more details about this kind of steel pipe? What are the type and application of welded steel pipes? Let us give you a basic introduction.

Because the cost of welded steel pipe is lower than that of seamless steel pipe and the production efficiency is higher, and thus seamless steel pipe is gradually replaced. The rapid development of welded steel pipe like straight seam welded steel pipe is inseparable from the support of national policy including the support during the eleventh five-year plan period and the 12th five-year plan. And an overseas oil and gas pipeline network covering the whole country has gradually formed. Anything related to steel pipes is liable to corrosion. Therefore, Ni is added into the T-welding steel pipe so that it is not easy to be corroded in the acidic environment, which also enhances the corrosion resistance of the round steel pipe. Of course, there are many kinds of welded steel pipe such as square steel pipe, rectangular steel pipe as well as round steel pipe mentioned above. They all play an important role in large industries.

Welded steel pipes are classified according to different requirements and there will be different ways of classification such as welding methods, wedding shape as well as actual application. The above is a rough introduction and classification of welded steel pipes. However, if you want to know more comprehensive information about welding steel pipe, you still need to search a special website for more detailed information especially for professional China steel tube manufacturers who need to provide customers with first-hand information so that they can win customer trust.
