Product Description

Welded Carbon Steel Pipe

Welded steel pipe, also known as welded pipe, is a steel pipe made by welding steel plates or strips after being rolled and formed, usually with a fixed length of 6 meters. The production process of welded steel pipes is simple, with high production efficiency, multiple varieties and specifications, and less equipment investment, but generally lower strength than seamless steel pipes.
