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.Differences Between ERW and HFW Steel PipeHigh frequency welding (HFW) is mainly used for ordinary or thin-walled steel pipes.It includes contact welding and induction welding.DC welding is usually used for small diameter steel pipes.Generally,HFW is one of ERW production methods,which uses high-frequency welding technology.Difference Between HFW Steel Pipe and ERW Steel PipeDate 2020-04-07 keywords erw steel pipe,hfw steel pipe The changes in the names of ERW and HFW change with the development of technology and the update of standards.First of all,the equipment for high-frequency resistance welding steel pipes is produced in Germany,and the earliest domestic production lines are in Baoji and Jinxiculudao.
