  • Differences between ERW Steel Pipe and HFW Steel Pipe

    Differences between ERW and HFW steel pipe. First is to know the differences of the ERW, HFW welding processes. ERW welding process refers the heat generated by the resistance to current flow that pass through the jointed metals. So a large current is needed to electrify the whole surface of the steel plate or coil to the length of welding.

  • Electric resistance welding - Wikipedia

    Low-frequency electric resistance welding, LF-ERW, is an obsolete method of welding seams in oil and gas pipelines. It was phased out in the 1970s but as of 2015 some pipelines built with this method remained in service. Electric resistance welded (ERW) pipe is manufactured by cold-forming a sheet of steel into a cylindrical shape.
