Ganpat Industrial Corporation has served Indian and export piping buyers since 1997. Alloy Steel F22 Threaded Fittings carry a 2.25% chromium, 1% molybdenum core. This chemistry resists high-temperature hydrogen attack better than carbon or F11 steel. We supply ASTM A182 F22 Elbows, Tees, Couplings, Unions and Plugs. Every fitting is dimensioned to ASME B16.11 and threaded to ASME B1.20.1. We forge, heat treat and machine each batch at our Mumbai facility. This makes us a reliable Alloy Steel F22 Pipe Fittings source. Every despatch carries an EN 10204 3.1 mill test certificate. We regularly supply this range to Vadodara, Chennai and Kandla. We also export to Dubai, Jebel Ali, Rotterdam and Houston.
