ASTM A790 Duplex Stainless Steel Pipe refers to seamless and welded pipe made from duplex stainless steel alloys, which combine the strength of ferritic steel with the corrosion resistance of austenitic steel. These pipes typically contain high levels of chromium (≥22%), nickel, and molybdenum, offering excellent resistance to pitting, crevice corrosion, and stress corrosion cracking.
Key Features:
Material Grades: Includes S31803 (2205), S32205, S32750 (2507), etc.
Mechanical Strength: Higher yield strength than standard austenitic stainless steels like 304/316 - ideal for structural applications.
Corrosion Resistance: Superior resistance in chloride-rich and acidic environments, making it ideal for offshore, marine, chemical, and desalination applications.
Applications: Oil & gas pipelines, heat exchangers, pressure vessels, marine equipment, and chemical processing systems.
Standards & Specifications:
Standard: ASTM A790 / ASME SA790
Sizes: Typically ½" to 24" NPS (custom sizes available)
Types: Seamless or welded
Wall Thickness: SCH 10S to SCH 160S and heavier
Delivery Condition: Solution annealed and pickled or polished
