ERW/HFW/HFI PIPE 鈥 MKS PIPE & STEEL

Electric Resistance Welded/High Frequency Welded/High Frequency Induction pipe, ranging from 1鈦4鈥 to 26鈥 diameter. We supply ERW/HFW pipe in a variety of grades meeting ASTM/ASME and API5L standards including A/SA53, A500, API5LB, X42, X46, X52, X56, X60, X65, X70, X80 in both PSL 1 and PSL 2. Differences between ERW Steel Pipe and HFW Steel 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. SAWH Finish Erw Carbon Steel Pipe HFW HFI ERW SAWH High quality SAWH Finish Erw Carbon Steel Pipe HFW HFI ERW SAWH SAWL EN 10224 EN 10219-1/2 from China, China's leading Nickel Alloy Pipe product market, With strict quality control Nickel Alloy Pipe factories, Producing high quality SAWH Finish Erw Carbon Steel Pipe HFW HFI ERW SAWH SAWL EN 10224 EN 10219-1/2 products. Difference between ERW, HFW, SAW and EFW pipe 鈥 HFW pipe is widely used in the fields of oil and gas transportation, oil well pipeline, building structure, and various kinds of mechanical pipe. However, HFW steel pipe quality is affected by many factors, such as raw material and process. And ERW Welded Steel Pipes, ERW Welded Steel Pipes suppliers
