Differences between ERW Steel Pipe and HFW Steel Pipe

High frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHZ.Through high-frequency current welding resistance,the heat generated in the contact objects,so the objected surface are heated to the plastic state,then with or without forging to achieve a combination of steels.EFW pipe vs ERW pipe ,page2.
