These Stainless Steel ERW Pipe are accessible in a number of categories, grades and sorts and they are utilized in a wide number of applications such as dairy and nourishment preparing, manufactured Difference between Seamless and erw Stainless steel pipe Nov 24, 2014 · What is the Difference Between Seamless and ERW Stainless Steel Pipes? Electric Resistance Welding (ERW) pipe is manufactured by rolling metal and then welding it longitudinally across its length. Seamless pipe is manufactured by extruding the metal to the desired length; therefore ERW pipe have a welded joint in its cross-section, while seamless pipe does not have any joint in its

Differences between ERW Steel Pipe and HFW Steel Pipe

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). Electric Resistance Welded Pipe, ERW Steel Pipes, Electric High-frequency electric resistance welding (ERW) steel pipe production, internal weld surface treatments are generally incomplete curettage (left weld reinforcement) and complete curettage (scraping will form the inner surface of the groove) in two ways, and the results were not ideal, will affect the overall performance of the steel pipe. Metal Pipe - Seamless Pipe - ERW Pipe - Galvanized Pipe Both are available in carbon steel and stainless steel. Welded pipe is also called ERW (Electric Resistance Welded) pipe. Most common specification for welded carbon steel pipe is A53. Seamless pipe is made by a process that requires no welding. Most common specification for seamless carbon steel pipe is A106B. Stainless Steel pipe is made to spec A312.
