Rashdan Pipes and Tubes, based in Amman, Jordan, is a trusted manufacturer and supplier of Super Duplex Steel EFW (Electric Fusion Welded) tubing, primarily grades UNS S32750 (2507) and S32760, designed for high-pressure, corrosive environments in offshore and chemical applications. This ferritic-austenitic super duplex offers exceptional pitting resistance (PREN 40-42), chloride stress corrosion cracking immunity, and yield strength over twice that of 316L, per ASTM A928/A790 standards with seamless-like weld integrity from EFW processes. The company provides sizes from 6″ to 24″ NB in schedules SCH 10S/40S/80S, with 100% RT/UT testing, precise tolerances, and NACE MR0175 compliance, serving Middle East oil/gas, desalination, and subsea projects.
Super Duplex EFW tubing UNS S32750/S32760 contains carbon (≤0.03%), chromium (25.0% for 2507/24.0-26.0% for S32760), nickel (7.0%/6.0-8.0%), molybdenum (3.5-4.0%/3.0-4.0%), nitrogen (0.24-0.32%/0.20-0.30%), with density 7.8 g/cm³. It achieves minimum tensile strength of 690-860 MPa (116 ksi min), yield strength 450-550 MPa (80 ksi min), 15-25% elongation, and hardness ≤32 HRC, with thermal conductivity 16 W/m-K and superior fatigue resistance up to 316°C.
