A METHOD FOR PRODUCING ELECTRIC RESISTANT WELDED (ERW) TUBES FOR PLUMBING APPALICATION

摘要

A method for producing electric resistance welded (ERW) tubes for plumbing applicationcomprises preparing hot rolled steel strip and processing the strip by rolling in a conventionaltube rolling line for producing ERW tubes. The ERW tubes produced are galvanized. Themethod is characterized by preparing the hot rolled strip from low carbon boron carbide steeltreated with coarse grain ferritic microstructure and the hot rolling of strip being carried outindependently of any further normalizing treatment.[IN236688A1]
