ASME B16.9 Eccentric Reducer Manufacturers, Stockist, Suppliers – Seamless Reducer, Welded Reducer, Large Diameter Fabricated Reducer Factory

  • We are a specialist manufacturer of eccentric reducer in size range of 1/2″ to 48″ in accordance with ASME B16.9. We also produce custom size reducers as per design or drawing from our customers. Eccentric reducers can be manufactured in seamless, welded or fabricated form. While seamless reducers can be produced upto size of 24″, we can produce welded and fabricated reducers upto a size range of 48″ or even higher in some cases.
  • An eccentric pipe reducer fitting is manufactured with the smaller outlet off center to the larger end, which allows it to align with only one side of the inlet. The reducer must be installed with straight side up so that it can prevent trapping air at the pump suction. The eccentric pipe reducers allow simple connection of different sized pipes.
  • They are used where the diameter of the pipe on the upstream side of the fitting is larger than the downstream side. We offer the most competitive prices for various pipe fittings.

Uses of Eccentric Reducers:

  • Keeping big pipes and small pipes together.
  • Reducing noise and vibration at the same time.
  • Requires less installation space.
  • Absorbs pipe wall and fluid borne noise.
  • Less turbulence or material entrapment.
  • Eccentric reducer are used with flat side up in pump suction to avoid cavitation.

Applications of Eccentric Reducer

  • Petrochemical industry
  • Pharmaceutical industry
  • Food industry
  • Aviation and aerospace industry
  • Architectural decoration industry
  • Oil and Gas Pipeline industry
