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.
Differences between ERW Steel Pipe and HFW Steel PipeThe 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.
ERW Steel Pipe is also called Electrical Resistance Welding Steel Pipe (HFW STEEL PIPE). ERW steel pipe is one of our most professional products. And it is not as the same as an ordinary pipe welding process, the welding basic metal is melted by its own steel body, so it has better mechanical strength than the normal welded pipe.
ERW Pipe Manufacturing Company & ERW Pipes suppliers Welded Pipe. Our manufacturing facilities, perform three types of welding processes:ERW, LSAW, HSAW and Anti corrosions. The facilities are fully equipped with the world's utmost advanced full auto production lines and lab test equipment which allows us to provide the quality of our product.

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.
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.
