Eccentric Reducer
Eccentric Reducer
High-quality Eccentric Reducer manufactured for smooth flow, strong welded joints and reliable performance in process piping.
- ASME B16.9
- Seamless
- Welded
- SCH 5S – XXS
- 1/2" – 48" NB
Eccentric Reducer Manufacturer in India
Sawariya Metal Industries is a manufacturer, supplier, stockist and exporter of Eccentric Reducer in stainless steel, carbon steel, alloy steel, duplex, nickel alloy and other grades, in a wide 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.
Key Features of Eccentric Reducer
Flat Side
Flat top avoids air pockets at pump suction.
Drainable
Flat bottom allows full drainage in racks.
Smooth Flow
Butt-welded joints give a smooth bore and low pressure drop.
High-Pressure Ready
Suited to high-pressure, high-temperature service.

Related Buttweld Fittings
Barred Tee
A barred tee has guide bars welded across the branch opening so that pipeline pigs pass the branch without entering or getting stuck.
Lateral Tee (Y-Tee)
A lateral tee has a branch at 45° (or another angle) to the run, giving a smoother flow path than a 90° tee for slurry, drainage and solids handling.
90 Degree Long Radius Elbow
A 90° long radius (LR) elbow changes the pipe direction by 90° with a centre-to-end radius of 1.5 times the nominal pipe size, giving lower pressure drop and smoother flow than a short radius elbow.
Technical Note: Dimensions, pressure ratings and material properties should be verified against the applicable ASME / MSS / DIN / ISO standard, approved drawings, purchase order and Mill Test Certificate (MTC) before final use.
