Luke Steel, founded in 1995 and headquartered in Houston, Houstan, has developed an exemplary reputation as one of the leading manufacturers and suppliers of Carbon Steel WPHY 56 Pipe Fittings. Expertise in high-performance piping solutions, the company satisfies the stringent needs of industries demanding dependable, pressure-resistant systems. Focused on quality, precision engineering, and customer satisfaction, Luke Steel provides WPHY 56 fittings as per international standards. Compliant with the best manufacturing practices, using high-tech manufacturing processes, expert professionals, and rigorous quality check, the firm facilitates prompt delivery and reliable solutions to key industry verticals such as oil & gas, petrochemicals, power, and infrastructure—within the USA and worldwide.
Carbon Steel WPHY 56 Pipe Fittings are made from a highly resistant alloy of carbon, manganese, phosphorus, sulfur, and silicon, offering greater strength and structural reliability. These fittings provide a minimum yield strength of 56,000 psi (about 386 MPa) and exhibit superior tensile strength, impact resistance, and weldability. These fittings are then strengthened by applying heat treatments in the form of normalizing and quenching, which improve their pressure-handling capacity and durability. The chemical and mechanical composition of WPHY 56 provides superior performance under harsh conditions, and these fittings are suitable for high-pressure flow systems carrying fluids and gases.
