Our stainless steel pipe bends & U‑return bends are manufactured by mandrel bending / hot induction bending process. Used to change fluid direction in pipeline systems, available in 45°, 90°, 180°(U‑bend) and any custom bending angles. Smooth inner surface reduces fluid resistance and turbulence. Widely applied for heat exchanger, petrochemical, power plant, marine, food‑pharmacy processing piping systems
✅ Premium raw material: SS304 / 304L / 316 /316L / Duplex steel available
✅ Smooth mandrel bending, no wrinkles or cracking on inner wall
✅ Butt‑weld end for on‑site welding installation
✅ Custom bending radius: 1.5D,3D,5D,10D or non‑standard radius
✅ Multiple surface finish: pickled, polished, sand‑blasted
✅ Strict dimension inspection, meet ASME B16.49 & ASTM A403 standard
✅ OEM & custom drawing service supported
