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).

WHAT ARE ERW/GP/GI/MS PIPES & TUBESTHEIR

Sep 16, 2020 · In the Electric resistance welded (ERW) manufacturing process, the pipe is manufactured by cold-forming a flat sheet of steel into a cylindrical shape. Then the current is passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material. ZENITH STEEL PIPES & INDUSTRIES LIMITEDERW GI PIPES. The QC accepted bare pipes are washed in solution of caustic soda tank followed by pickling by hydrochloric acid of suitable concentration to remove oxides on pipe surface & is then dipped in fluxing tank. Pipes are then preheated & dipped in molten zinc bath. Pipes are then pulled out from the bath & wiped externally & internally for uniform & smooth zinc coating.
