Difference between ERW, SSAW, LSAW - Alloy Pipe, Tubes High frequency straight seam welding (ERW) method is divided into two forms of induction welding and contact welding, hot-rolled wide volume as raw material, pre-curved, continuous molding, welding, heat treatment, sizing, straightening, cutting, etc. process, compared with the spiral weld short, high dimensional accuracy, uniform thickness, surface quality, pressure advantages, but the drawback is Differences Between ERW and HFW Steel PipeNov 02, 2020 · 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).
EFW pipe vs ERW pipe. Electric Fusion Welding (EFW steel pipe) refers to an electron beam welding, the use of high-speed movement of the electron beam directed impact kinetic energy is converted to heat the workpiece so that the workpiece leaving the melt, the formation of the weld.. It is mainly used for welding dissimilar steel welding sheet or which high power density, metal weldment can ERW Pipe Electric Resistance WeldedElectric Resistance Welded (ERW) pipe is manufactured by cold forming a flat steel strip into a rounded tube and passing it through a series of forming rollers to obtain a longitudinal seam. The two edges are then simultaneously heated with a high frequency current and squeezed together to form a bond. ERW Piping - Electric Resistance Welded Pipe at Detroit During the process of creating ERW tubing, the piping may either be hot rolled or cold rolled, which has a drastic change on the outcome of electric resistance piping. Also created from the electric resistance welding process is DOM tubing. HREW or Hot Rolled ERW is rolled at high temperatures.
