  • Differences between ERW Steel Pipe and HFW 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). ERW steel pipe

  • Types of Oil & Gas PipesSeamless, ERW, LSAW

    ERW pipes are available in sizes between 1/2 and 20 inches, in carbon steel (ASTM A53 is the most common specification) and stainless steel (ASTM A312). In terms of dimensions, the ASME B36.10 and ASME B36.19 are the key reference specifications (API 5L for welded ERW line pipes).

  • Difference between Seamless & ERW Stainless Steel pipe

    To Manufacture ERW Stainless Steel Pipes HR Coils are required. Major Indigenous suppliers of these HR Coils are SAIL, Essar, JSW, Lloyds etc. 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.

  • ERW (Electric Resistance Welding ) Pipe – Jiang Lin Steel

    ERW (Electric Resistance Welding ) Pipe is produced from individual sheets or continuously from rolls of skelp.ERW Pipe is cold formed into a cylindrical shape rather than hot formed. An electric current rather than a flame is used to heat the edges of the strip for the fusion weld.ERW Pipe is subject to numerous finishing operations.
