Alloy Steel Socket Weld Fittings are precision-forged components designed for high-pressure, high-temperature, and critical service piping systems. These fittings are alloyed with chromium and molybdenum to provide excellent mechanical strength, creep resistance, oxidation resistance, and long-term reliability.
Alloy Steel Socket Weld Fittings are widely used in power plants, oil & gas refineries, petrochemical units, chemical processing plants, and industrial piping where leak-proof, compact, and vibration-resistant joints are required.
Alloy Steel Socket Weld Fittings are manufactured in accordance with ASTM A182 and ASME SA182 standards. Commonly supplied grades include F1, F5, F9, F11, F12, F22, and F91, each engineered for specific temperature, pressure, and corrosion resistance requirements.
