The black horse in the steel tube market—welded steel pipe

When mentioning the word “steel pipe”, we will make a closely relationship between construction sites and steel pipe industry and we may think that steel pipe such as square steel pipe is far away from our life. I am afraid that that thought is probably wrong. Actually, steel pipe is closely related with our daily life. For example, we should use water and oil which are transported by the vehicle-steel pipe. And steel pipe bring great convenience to us. Except for seamless steel pipe, steel pipe manufacturers can also produce galvanized steel pipe, welded steel pipe and so on.

What is the difference between welded steel pipe and seamless steel pipe. According to the pipe term, we can know that seamless steel pipe is made by special production process and its surface is quite smooth. While the main processing technology of welded steel pipe is welding after the forming of round steel pipe or square steel pipe. So we can see the welding line on the pipe surface. Seamless steel pipe has its own advantages such as strong press-proof performance. At the same time, its manufacturing process is very complex and of course, the production cost is also very high which is destructive to sale volume. In the recent years, there is a great progress in the production of welded steel pipe. Therefore, welded steel pipe can catch up with seamless steel pipe gradually to some extent. Moreover, the shape of welded steel pipe is multiple such as rectangular steel tube. In addition, the steel pipe price of welded steel pipe is lower than that of seamless steel pipe, so the former is more and more popular in the steel pipe market. The high production technology provides us a basis to take all the necessary steps to carry out mass production and promote pipe quality if we have confidence in making first-rate products with our good-faith efforts.

Welding steel tube is a general term which can be divided into various category with different classification standards such as spiral steel pipe, straight seam welded steel pipe, rectangular steel tube and so on. Of course, more and more steel pipe manufacturers give customers customized service according to their special demands. For example, galvanized steel pipe is mainly suitable for those who want to high anti-corrosion performance. For steel pipe suppliers, the main advantage of competition is to make more steel pipes of different sizes.
