GNEE offers high-quality ASTM A815 WP-S UNS S32205 duplex stainless steel 180-degree U-bends, fully compliant with ASTM A815 standards. We provide a complete range of U-bend sizes, covering DN15-DN300 (NPS 1/2"-12"), with wall thickness options from SCH10 to SCH160, and precise dimensional tolerances (angle tolerance ±0.5°, wall thickness tolerance ±3%, bending radius tolerance ±5%), ensuring a perfect match with S32205 pipes. These U-bends are made from homogeneous S32205 duplex stainless steel (PREN 32-35), offering consistent corrosion resistance and strength, with a yield strength of ≥450MPa and tensile strength of ≥620MPa, and complying with NACE MR 0175/ISO 15156 standards, suitable for harsh working environments.
All U-bends undergo rigorous quality inspection, including X-ray testing (100% weld inspection) and hydrostatic testing (1.5 times working pressure). GNEE offers standard stock and customized services, with fast delivery to global markets, including Europe, the Americas, and Asia.
