Stainless steel welded pipe, referred to as welded pipe, commonly used steel or steel strip after the unit and mold crimped forming welded steel pipe. Welded steel pipe production process is simple, high production efficiency, variety specifications, less equipment investment, but the general strength is lower than seamless steel pipe.

Since the 1930s, with the rapid development of high-quality strip continuous rolling production and the progress of welding and inspection technology, the quality of welds continues to improve, and the variety specifications of welded steel pipes are increasing, and in more and more fields, especially in the heat exchange equipment with pipes, decorative pipes, medium and low pressure fluid pipes and other aspects of the replacement of seamless steel pipes.
