Stainless steel welded pipe, referred to as welded pipe for short, is a steel pipe that is usually made by welding steel or steel belt after being rolled by the unit and the mold. Welded steel pipe production process is simple, high production efficiency, many varieties and specifications, less equipment investment, but the general strength is lower than seamless steel pipe.

With the rapid development of high-quality strip continuous rolling production and the advancement of welding and inspection technology, the quality of welding seams is constantly improving, and the variety and specifications of welded steel pipes are increasing.

According to the weld form, it is divided into straight seam welded pipe and spiral welded pipe.

According to the use, it is divided into general welded tubes, heat ex-changer tubes, condenser tubes, galvanized welded tubes, oxygen-blown welded tubes, wire sleeves, metric welded tubes, idler tubes, deep well pump tubes, automotive tubes, transformer tubes, electric welding thin-wall Pipe, welded special-shaped pipe and spiral welded pipe.
