Rashdan Pipes and Tubes, based in Amman, Jordan, is a premier manufacturer and supplier of Super Duplex Steel welded tubing, primarily UNS S32205 (2205 grade), engineered for extreme corrosion resistance and high strength in harsh environments. This ferritic-austenitic stainless steel combines 22% chromium, 5-6% nickel, and 3% molybdenum for superior pitting resistance (PREN 30-38), stress corrosion cracking immunity up to 150°C, and twice the yield strength of 316L, per ASTM A790/A928 standards. The company offers welded tubing in sizes from 1/2″ to 24″ NB with schedules like SCH 10S/40S, precise tolerances, and NDT testing, serving Middle East oil/gas, desalination, and chemical sectors for subsea, offshore, and pressure applications.
Super Duplex S32205 welded tubing features carbon (≤0.03%), manganese (≤2.00%), chromium (22.0-23.0%), nickel (4.5-6.5%), molybdenum (3.0-3.5%), nitrogen (0.14-0.20%), silicon (≤1.00%), phosphorus/sulfur (≤0.030%/0.020%), with density of 7.8 g/cm³. It delivers minimum tensile strength of 620-880 MPa, yield strength of 448-550 MPa, 25% elongation, and hardness ≤28 HRC/293 HB, with thermal conductivity of 16 W/m-K and modulus of 200 GPa for excellent fatigue and formability.

Super Duplex S32205 welded tubing excels in offshore oil/gas for subsea umbilicals, flowlines, and risers resisting chloride pitting and sour service. In desalination and chemical plants, it handles seawater, sulfuric acid, and brackish fluids in heat exchangers, condensers, and pressure vessels. It also serves in pulp/paper, power generation, and structural piping where high strength reduces weight, available in welded ERW/EFW forms for superior SCC resistance and longevity in aggressive environments.
