Differences between ERW Steel Pipe and HFW Steel Pipe

It shall be noted that HFW pipe is a type of ERW 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 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 is heated to the plastic state, then with or without forging to achieve a combination of steels.What is a HFW steel pipe? ugsteelmillThe high frequency welding (HFW) is mainly used in ordinary or thin wall steel pipe. It includes contact welding and induction welding. Direct current welding is generally used for small caliber steel tubes. In general, HFW is one of ERW production methods, it adopts the high frequency welding process. So, ERW steel pipe includes HFW steel pipe.

The differences between ERW and HFW steel pipe, is EFW is a type of ERW process for ordinary and thin wall thickness steel pipes.Manufacturing Process for Welded Pipes. How To Produce Less thickness pipe, mainly ERW / EFW or HFW welded pipe are formed by continues rolling method. In this method, a flat metal strip from the strip coil is feed into the series of roller assembled in line. These rollers gradually form the strip in the circular section. At the end of rolling assembly, this pipe is continuously welded by welding

What is the difference between HFW and ERW?

High frequency welding (HFW) is a solid resistance heat energy. The use of high frequency current welding resistance heat generated in the workpiece so that the workpiece is heated to melt the welding area or near the surface of the plastic state, then applied (or not applied) forging force and achieve a combination of metals.Welspun Corp.US$ 3 billion Welspun Group is an amalgamation of expertise, resources, opportunities and engineering excellence.
