Product details

Eccentric Reducer

Eccentric reducer is a butt-weld pipe fitting used to connect pipes of different diameters. Its centerlines are offset, so one side of the fitting keeps a straight edge. It is mostly installed on horizontal liquid pipelines.

Stainless steel eccentric reducer with offset centerline and one straight side

The eccentric reducer is a butt-welded reducing fitting with non-coaxial centerlines. One side maintains a continuous straight surface, which is its core feature distinguishing it from the concentric reducer. It is primarily designed for horizontal liquid pipelines.

Advantages

  • The offset structure eliminates the high point where gas can be trapped, preventing vapor lock and guaranteeing continuous liquid transport.
  • Suitable for liquids, oil and mediums containing sediment, helping avoid gas accumulation.
  • Smooth internal transition minimizes flow disturbance, pressure drop and inner wall erosion.
  • Easy to align and weld on horizontal pipe racks.
  • Various material options: carbon steel, stainless steel, alloy steel, duplex steel, with MTR test certificates supplied.
  • Compliant with ASME B16.9, ASTM standards, widely applied in petrochemical, refinery, seawater desalination and pipeline projects.
