What is Stainless Steel Welded Pipe

Stainless Steel Welded Pipe always used stainless steel or stainless steel strip is welded by the unit and the mold after crimp forming. As usual. Stainless Steel Welded Pipe may divide into two types such as electric resistance welded steel tube (ERW, SSAW) and Spiral welded steel pipe. It has an easy manufacturing process, high production efficiency, many varieties, and dimension. Some stainless steel welded pipes are finished through related surface treatment such as zinc plating and black coating, then their function and advantage of usage are in a more broad range.
