Pipe Bends (3D, 5D, 10D) for changes in direction, branching and size transitions, available on MetalMitra in seamless, welded and fabricated to ASME B16.9, with mill-certified traceability on every lot.

Through MetalMitra you can source Pipe Bends (3D, 5D, 10D) in stainless steel, carbon steel, alloy steel, duplex, nickel alloy and other grades, across a broad range of sizes and pressure ratings.

Pipe bends are large-radius buttweld bends made by induction or cold bending, with radii such as 3D, 5D and 10D for low-turbulence flow and pigging-friendly pipelines.

Buttweld fittings are bevelled at the ends and welded directly to the pipe, giving a continuous, leak-resistant joint with a smooth bore and low pressure drop. They are the standard choice for process piping above 2" NB and for high-pressure, high-temperature service.

Product range

  • Elbows — 45°, 90° and 180° long and short radius elbows.
  • Tees & Crosses — Equal and reducing tees and crosses.
  • Reducers — Concentric and eccentric reducers.
  • Stub Ends & Caps — Lap joint stub ends and pipe end caps.

Why engineers choose it

  • Large Radius — 3D, 5D and 10D radii for smooth flow.
  • Pigging Friendly — Suitable for pipelines that require pigging.
  • Smooth Flow — Butt-welded joints for a smooth bore and minimal pressure drop.
  • High-Pressure Ready — Rated for high-pressure, high-temperature service.
