Product Description

A straight seam steel pipe is a circular pipe made of flat steel bars or steel plates, and connected through a straight seam welding process. Among them, high-frequency welding, Submerged arc welding and other methods can be used for welding process. When welding straight seam steel pipes, the long and short welds follow the length direction of the pipe, presenting a linear appearance. Additionally,ERW PiPe it should be noted that in order to improve the pressure test performance of straight seam steel pipes, heat treatment or cold processing is usually performed on the welding area during the production process to improve it. Straight seam steel pipes are widely used in industries that require special usage conditions such as high pressure and temperature, as well as conveying various fluids and gases.
