Machine Pictures

Welded steel pipe, also called welded pipe, is a steel pipe made by welding and forming a steel plate or strip steel. 

It is usually 6 meters long. 

The welded steel pipe has simple production process, high production efficiency, many varieties and specifications, and low equipment investment, but the general strength is lower than that of seamless steel pipe.
