ERW-HFW(HIGH-FREQUENCY WELDED) CARBON PIPES

Sep 12,2014·For the record,the electric resistance welding (ERW) process is not just an early process,it is an ongoing process still used in a significant number of pipes,mostly 24-inch and below.ERW is specified in all pipeline design (ASME B 31.4 and B 31.8,for example) and pipe-making specifications.There is no regulatory restriction on the use of these pipes in oil-carrying pipelines.Images of ERW High Frequency Welded Carbon Steel Tube imagesERW Carbon Steel Tube Mill ERW Carbon Steel Tube Mill ERW355 Oil Gas Pipe Production Line ; ERW426 Steel Pipe Making Machine ; HG32 High-Frequency Welded Carbon Steel Tube Mill ; HG50 HF Welded Pipe Mill Making Machine ; HG76 ERW Carbon Steel Pipe Making Machine ; High Speed Diameter 114 mm ERW Carbon Steel Tube Mills Pipe Making Machine ; HGF200 Square Pipe Making Machine ; HGF150 Square Pipe Making MachineRelated searches for erw high frequency welded carbon steerw steel tubeerw steel pipeerw steel pipe spec sheetswhat is erw pipeastm a53 erw steel pipeerw tubing specificationserw tubingwhat is erwSome results are removed in response to a notice of local law requirement.For more information,please see here.12345NextWelded Standard Line Pipe US Steel Tubular ProductsEnergy-specific high frequency electric weld (ERW) tubular products that are developed,tested,and produced in the United States.U.S.Steel Tubular Products high frequency electric weld (ERW) line pipe and standard electric resistance weld pipe products are smoothly finished and thin-walled.They are produced by continuously forming coiled hot rolled strip into a tube and welding the longitudinal seam using high-frequency electric resistance welding.

What is Welded Steel Pipe

There are different welding methods used to weld the pipe.ERW- Electric Resistance Welding.EFW- Electric Fusion Welding.HFW- High-frequency welding.SAW- Submerged Arc Welding (Long seam Spiral Seam) API 5L or ASTM welded steel pipe includes LSAW pipe,SSAW pipe,and ERW steel pipe.Welded Pipe Advantages:
