Super Duplex 2507 Seamless Tubes are designed for challenging applications where high strength, high accuracy and corrosion resistance are essential. These tubes are made of solid billet of Super Duplex Stainless Steel without any welded joint and have a uniform wall thickness with superior dimensional accuracy and a high-pressure rating. The yield strength of pipes is a minimum of 550 MPa or 80 ksi, and the pipes contain approximately 25% Chromium, 7% Nickel, 4% molybdenum, and 0.24- 0.32% nitrogen. Excellent in resisting pitting, crevice corrosion and chloride stress corrosion cracking. These pipes are available in various dimensions, sizes, and even customized lengths according to the requirements of various industries in accordance with ASTM A789/ASME SA789 standard. USA Piping Solution is a trusted Super Duplex 2507 Seamless Tubes Manufacturer and Supplier, offering precision-engineered seamless tubes of consistent quality with a long service life and reliable performance.
