Assuring consistent performance and structural dependability, these pipes are made from carbon-manganese steel plates and adhere to ASTM A671 standards. Luke Steel provides robust, tested, and certified piping solutions to vital industries like petrochemical processing, power generation, and oil and gas. Luke Steel continues to be a go-to supplier for premium-grade welded steel pipes because of its unwavering dedication to quality, prompt delivery, and customer service.
Carbon Steel A671 Gr CC 65 Pipes are made from carbon-manganese steel plates, which are usually composed of sulphur (≤0.030%), phosphorus (≤0.030%), manganese (0.90–1.60%), and carbon (≤0.30%). These pipes have a minimum yield strength of 35,000 psi and a tensile strength of roughly 65,000–85,000 psi. They are made for electric fusion welding and have exceptional structural strength. The material provides dimensional stability, toughness, and dependable weldability. To guarantee safety and performance under demanding service conditions, A671 CC 65 pipes are subjected to extensive testing, including hydrostatic and ultrasonic examination.
