Abstract This specification covers standard requirements for ferritic/austenitic (duplex) stainless steel pipe that is electric fusion welded with addition of filler metal suitable for corrosive service. Heat treatment shall be performed after welding and in accordance with specified temperature and quench conditions. Several grades of ferritic/austenitic steel shall conform to the requirements of the applicable specification and grade designation. Heat and product analyses shall be conducted and shall conform to the requirements for the particular grade. The plate used in making the pipe shall conform to the required tensile properties. The steel pipe shall undergo several mechanical tests including transverse tension test, transverse guided-bend test, nondestructive test, hydrostatic test, and nondestructive electric test.
