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). results for this questionWhat ' s The difference between ERW and seamless steel pipe?What ' s The difference between ERW and seamless steel pipe?E) The impact toughness of ERW steel pipe is higher than that of seamless steel pipe.F) Longitudinal resistance welded pipe is not welded into the dissimilar metals,but also undergo a rigorous on-line heat treatment,so the basic performance of the weld and material properties.ERW Steel Pipe
Company Profile Specialist supplier of steel pipes and fittings since 2006; EPC sources from us! Hebei Yongqiang Pipeline Co.is a professional supplier and distributor of stainless steel pipe and tube with our own factory.The factory covers a land area of 135,000 square meters with more than 200 employees,we have an annual capacity of 20000 tons with professional and advanced production Difference between Seamless ERW Stainless Steel pipeERW (Electric Resistance Welded) pipes are welded longitudinally,manufactured from Strip / Coil and can be manufactured upto 24 OD.ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through a electric charge.
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.EFW pipe vs ERW pipe ,page2.
