Reducer

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

    Eccentric reducer is most commonly used and often eccentric reducer used in piping in about pump and pipe rack area.

    These reducers are used in various applications that involved in high pressure, vibration & temperature. These reducers are widely used in chemical, petroleum, shipbuilding, gas, power sectors.

    Length of reducers The length of a Reducer is very short in relation to the diameter, so in some dimensions the transition from one to another diameter is very abruptly. For example, a reducer 6″ x 2½” has a length of 140 mm. On this short distance a pipeline will be reduced from 168.3 mm O.D. to 73 mm O.D. During the design phase of a new pipe system, a piping designer certainly must think about it.
