Hastelloy Buttweld Fittings are high-performance pipe fittings made from Hastelloy C22 and C276 alloys, designed to withstand extreme environmental conditions and highly corrosive applications. These fittings include a wide range of types such as Elbow, Tee, Eccentric Reducer, Concentric Reducer, Long Stub End, Short Stub End, Cap, and Cross Pipe End. Manufactured adhering to international standards ASTM B366 and ASME SB366, they conform to multiple dimension standards including ASME/ANSI B16.9, B16.28, MSS-SP-43, BS4504, BS1560, BS10, and MSS SP series. Available in sizes ranging from 1/2" to 48", these fittings can be seamless, ERW, welded, or fabricated, providing versatility for different industrial piping needs. Known for their high melting point of up to 1443°C (2430°F) and excellent mechanical properties such as elongation up to 30%, moderate tensile and yield strength, Hastelloy Buttweld Fittings find extensive applications in demanding industries like heavy oil refinery, petrochemical, nuclear power, bitumen upgrades, and acid processing. Supplied by top manufacturers and exporters in India, these fittings deliver reliable corrosion resistance and mechanical strength for critical piping systems requiring durability and long-term reliability.
