Stainless steel welded pipe is a steel pipe that is often welded by steel or steel strip after being extruded by components and dies. Welded steel pipes have simple production process, high production efficiency, many varieties and specifications, and low equipment investment, but usually the strength exceeds seamless steel pipes.

 

Since the 1930s, through the rapid development of high-quality strip continuous rolling production and the advancement of welding and inspection technology, the quality of welds has been continuously improved, and the variety and specifications of welded steel pipes have continued to increase. Heat equipment pipes, decorative pipes, medium and low pressure fluid pipes, etc. have replaced seamless pipes.
