These hot-dipped longitudinal seam welded pipe are ideal for seamless Welded steel pipe distributor in China for international The carbon steel pipe that forms to round or square shape by bending steel strips and plates and through welding process, is called welded steel pipes according to its definition. So simply understanding about welded pipes is the pipe with welding process, and you may find welding seam on the surface of welded steel pipes.

What Are Differences Between Spiral Welded Pipe and

Commonly, it is different in the properties of the two types of pipes. The welding process of spiral tube, straight seam steel pipe welding methods are varied from the previous process. So the probability of the presence of welding defects also greatly improved. The straight seam pipe will inevitably be a lot of T-weld. Which Industries are Straight Seam Steel Pipes Widely Used in?Sep 22, 2020 · No Comments. Longitudinal seam steel pipes are produced from strip steel, and the pipes obtained by longitudinal welding on high-frequency welding equipment are called straight seam welded pipes.
