Difference Between Seamless And Erw Pipe

ERW Pipe All Carbon steel pipe such as Casing pipe and Tubing pipe made to API specifications uses seamless or electric-weld supplying processes. There are Differences between ERW Steel Pipe and HFW Steel PipeERW steel pipe is manufactured through low or high frequency resistances Electric Resistance. Welding seam is in longitudinal. During the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond.
