Welded Steel Pipe

As its name indicates, the welded steel pipe comes with welding seams on its surface. It is usually manufactured using steel plate or strip steel which is bended into a square or round shape to be welded. As compared with seamless pipes, welded ones feature simple production process, so the production efficiency for welded ones is much higher than that for seamless ones, and the investment cost for production equipment is also much lower.

Along with the improvement in welding and testing techniques, the welding quality is constant improved, and the variety of welded pipes also increases. Due to this, welded tubes have been increasingly used to replace seamless ones.
