ASTM A672 B70 Carbon Steel EFW (Electric Fusion Welded) Pipe is a specific type of carbon steel pipe widely used in various industrial applications, particularly in the transportation of fluids and gases at elevated temperatures and pressures. This pipe is constructed using the electric fusion welding process, which involves the joining of two or more pieces of carbon steel using an electric arc. ASTM A672 B70 is a specific grade within this standard, and it is designed to meet specific mechanical and chemical requirements. The size range for ASTM A672 B70 Carbon Steel EFW Pipe typically spans from 16 inches to 120 inches in diameter, making it suitable for a wide range of applications. The wall thickness can vary from SCH 10 to SCH 80, corresponding to thicknesses ranging from 3mm to 12mm. Lengths can be single, double random, or customized to meet project-specific needs.
The chemical composition of ASTM A672 B70 Carbon Steel EFW Pipe includes elements such as carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, copper, molybdenum, and vanadium, all within specific limits to ensure the desired material properties. The mechanical properties, including tensile strength, yield strength, elongation, hardness, and impact toughness, are designed to meet the requirements of various applications. These pipes are subject to rigorous testing, which may include hydrostatic tests, ultrasonic tests, radiographic tests, tensile tests, impact tests, and more, to ensure their integrity and reliability in demanding environments.
