High-performance electric fusion welded (EFW) pipes for pressure and structural applications are available from Luke Steel, a reputable manufacturer and supplier of Carbon Steel A672 Grade CC 70 Pipes with its headquarters located in Houston, USA. These pipes are perfect for high-pressure, moderate-temperature settings because they are made from fine-grain carbon-manganese steel plates. Luke Steel guarantees consistent quality, strength, and durability in every product by closely adhering to ASTM A672 specifications. Luke Steel provides reliable piping solutions to petrochemical facilities, refineries, power plants, and other demanding industrial sectors across the United States through sophisticated manufacturing procedures, stringent inspection procedures, and an emphasis on customer satisfaction.
Carbon-manganese steel, which has a typical composition of carbon (0.30% max), manganese (0.90–1.60%), phosphorus (0.030% max), and sulphur (0.030% max), is used to make Carbon Steel A672 Gr CC 70 Pipe. With a tensile strength of 70,000 psi and a minimum yield strength of 38,000 psi, this grade provides increased strength. It provides outstanding weldability, impact resistance, and performance in high-pressure, moderate-temperature systems and is specifically designed for electric fusion welded applications. To guarantee structural integrity, dependability, and compliance with demanding service conditions, A672 Gr CC 70 pipes are subjected to extensive hydrostatic and nondestructive testing.
