Restricted to the steel industry, the term applies to all tubular products intended for conveyance of solids, liquids, and gases. Pipe can 
ERW 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.
