Eccentrice Reducer

Eccentrice Reducer

Eccentrice reducer is a kind of fitting that be used for reducing piping size. Eccentrice reducer is most commonly used and often eccentric reducer used in piping in about pump and pipe rack area.

An eccentric reducer 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.

Uses of eccentric reducers:

1. Keeping big pipes and small pipes together.

2. Reducing noise and vibration at the same time.

3. Requires less installation space.

4. Absorbs pipe wall and fluid borne noise.

5. Less turbulence or material entrapment.

6. Eccentric reducers are used with flat side up in pump suction to avoid cavitation.
