API 5L Line Pipe/ Sour Service Line Pipe -PSL1 & PSL2/ X52 SMYS Pipeline. HFW Pipe means high frequency welded pipe. EW pipe refers to tubular product having one longitudinal seam produced by low- or high-frequency electric-welding.According to API 5L spec HFW pipe refers EW pipe produced with a welding current frequency equal to or greater than 70 kHz.
Differences Between ERW Steel Pipe and HFW Steel Pipe May 16, 2018 · HFW is Required in API 5L PSL2 ERW Steel Pipe. According to the API 5L and ISO 3183 specification, for PSL 2 pipes in welded process, the HFW welding is a mandatory requirement 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).

SSG High-frequency longitudinally welded pipe production line is mainly used for the production of welded steel pipe of 8 ~ 610 mm and wall thickness of 0.5~ 20mm as well as the production of square, rectangular, and other custom seamless pipe profile, Carbon steel pipe, ERW steel Tube.
Electric Resistance Welded Pipe, ERW Steel Pipes, Electric High-frequency electric resistance welding (ERW) steel pipe production, internal weld surface treatments are generally incomplete curettage (left weld reinforcement) and complete curettage (scraping will form the inner surface of the groove) in two ways, and the results were not ideal, will affect the overall performance of the steel pipe.

What is ERW steel pipe - pipelinedubaiWhat is ERW steel pipe? ERW steel pipe is a straight seam electric resistance welded pipe, abbreviated as ERW pipe, which is a round pipe welded by steel plates. It is used to transport vapor and liquid objects such as oil and natural gas, and can meet various requirements of high and low pressure. At present, it plays an important role in the world of transportation pipes. 1 ERW 2
They are produced by continuously forming coiled hot rolled strip into a tube and welding the longitudinal seam using high-frequency electric resistance welding. Chemical and mechanical property requirements are as prescribed by current API 5L and applicable ASTM standards. *U. S. Steel Tubular Products ERW pipe is HFW as defined by API 5L.
