Difference between ERW, HFW, SAW and EFW pipe www

ERW pipes are manufactured using steel coils:the coil is first uncoiled, then smoothed, cut, and, finally formed into a pipe shape by joining its two extremities electrically. During ERW pipe welding, heat is generated when current flows through the contact surface of the welding area. Differences between ERW Steel Pipe and HFW Steel PipeHFW 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 of Spiral Pipe and ERW- Know It HereMay 05, 2021 · The ERW or Electric Resistance Welded pipe seems to appear longitudinally and the spiral pipes have helix shaped structures at the extremities. Pressure Resistance. Both the pipe types go through pressure test during manufacturing. The production stages cause the
