Abstract

This specification covers the standard for centrifugally cast austenitic alloy steel pipe for use in high-temperature, corrosive, or nuclear pressure service. The pipe shall receive a heat treatment at the required temperature and holding time followed by quenching in water or rapid cool by other means. The pipe shall be machined on the inner and outer surfaces and shall conform to specified roughness value. Heat and product analysis shall be done to determine the chemical composition and shall conform to the required carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, columbium, tantalum, and nitrogen contents. Hydrostatic and tension tests shall be performed and shall conform to the required tensile strength, yield strength, and elongation.
