Stainless Steel Welded Pipe, also known as welded pipe, is made of steel or strip after crimping and forming Steel Pipe. Welding steel pipe production process is simple, high production efficiency, variety specifications, equipment, less, but the general strength is lower than the Seamless Steel Pipe. Since the 1930s, with the rapid development of high-quality strip rolling and the improvement of welding and inspection technology, the quality of welds has been increasing continuously, and the specifications of welded Steel Pipes have been increasing and more and more fields have been replaced. Sewing steel pipe. Welded Steel Pipe in the form of welds are divided into straight seam welded pipe and spiral welded pipe.
