Eccentric Reducer for changes in direction, branching and size transitions, available on MetalMitra in standard and custom sizes to ASME B16.9, with mill-certified traceability on every lot.
Through MetalMitra you can source Eccentric Reducer in stainless steel, carbon steel, alloy steel, duplex, nickel alloy and other grades, across a broad range of sizes and pressure ratings.
An eccentric reducer joins pipes of different diameters with one flat side, preventing air pockets at pump suction and allowing drainage in pipe racks.
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
