Sep 23, 2020 · JCOE steel pipe:according to "J-C-O-E" pre-welding, forming, and cold expanding after welding HME steel pipe:It is formed by mandrel rolling method according to "C-C-O", welded and then cold-expanded. 2. The difference in welding ERW steel pipe welding does not need to add welding wire; LSAW steel pipe requires welding wire. 3. Differences between ERW Steel Pipe and HFW Steel PipeHigh 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.
