  • Differences between ERW Steel Pipe and HFW Steel Pipe

    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.

  • Electric Resistance Welded an overview ScienceDirect

    Feb 17, 2009 · When electric resistance welded carbon steel pipe was exposed to aggressive waters, grooves caused by the redistribution of sulfide inclusions along the weld line were formed in the weld. The material at the bond line is anodic to the surrounding material and the result is a V shaped groove with the apex of the V centered on the bond line.
