Differences between ERW Steel Pipe and HFW Steel Pipe

HFW is required in API 5L PSL2 ERW steel pipe According the API 5L and ISO 3183 specification, for PSL 2 pipes in welded process the HFW welding is a mandatory requirements for ERW steel pipes. As it is an improvement from the inherent problems of hardness, lack of fusion and susceptibility of stress corrosion cracking (SCC).Differences Between ERW Steel Pipe and HFW Steel Pipe In general, HFW is one of ERW production methods, it adopts the high frequency welding process. So, the ERW steel pipe includes the HFW steel pipe. ERW steel pipe application and usage. ERW steel pipe used for transporting gas and liquid objects such as oil and gas could meet the low and high pressure requirement.HFW ERW Pipes Ratnamani Metals & Tubes Ltd.HF ERW pipes are made from hot rolled flat steel strip, formed into tubular shape and the longitudinal seam is welded by the application of mechanical squeezing of edges and heating the edges through High Frequency Electric Resistance applied by induction or conduction. The weld joint is achieved without addition of any filler metal.

What is a HFW steel pipe? ugsteelmill

The 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.Structure Steel PipeStructure Pipe,ERW Pipe, High Frequency Weld Pipe, Structural Steel Tube, CS Pipe,structure steel pipe,ERW HFW steel pipe,high frequency weld pipe,circular hollow section,CHS .

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.API Steel Pipe API Seamless Pipe API 5L Line Pipe HFI/ HFW line pipe in sizes from 2 inches to 20 inches in diameter.
