In Electric Resistance Welding (ERW) process, pipe is manufactured by cold-forming a flat sheet of steel into a cylindrical shape. Then current is passed between the two edges of the steel cylinder to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material. Several Electric Resistance Welding (ERW) processes are available for pipe production. The two main types of ERW are: 1. See more on theprocesspiping erw steel pipew welded pipeFull Form of ERW Steel Pipe"ERW steel pipe" is a high-frequency straight seam resistance welded pipe, abbreviated as ERW, used to transport oil, natural gas and other vapor and liquid objects, can meet various requirements of high and low pressure, currently in the world The field of management occupies a pivotal position.Electric Resistance/ Fusion Welded (ERW and EFW)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.
