Carbon Steel WPHY 56 Pipe Fittings are tough, hot-formed components crafted to meet ASTM A860 standards, making them perfect for demanding pipeline systems. These fittings are built to handle higher pressures and mechanical stresses while ensuring top-notch dimensional accuracy and structural integrity. With a great mix of strength, toughness, and reliability, WPHY 56 fittings are ideal for critical service conditions. You’ll find them widely used in industries like oil and gas transmission, petrochemicals, refineries, power generation, and large-scale pipeline projects.
These fittings are made from carbon-manganese steel, featuring a carefully controlled chemical composition that includes carbon, manganese, silicon, phosphorus, and sulfur. This specific grade boasts a minimum yield strength of 56 ksi, along with impressive tensile strength, ductility, and impact resistance. They show excellent toughness and resist cracking under stress. Plus, their good weldability and consistent mechanical properties guarantee reliable performance in high-pressure piping systems.
