Concentric/Eccentric Reducer?

Reducer concept: A pipe fitting to reduce the diameter of a pipe during connection.

SHAPE:* Concentric reducers ( the central axes of the big and small ends coincide) ;

*Eccentric reducers ( the outer walls of the big and small ends are in a straight line).

FEATURES:the Eccentric reducer is widely used, because it can ensure that the pipeline has a same height above and below before and after the reducer, which is convenient to support. Sometimes concentric reducers are also used in order to prevent the occurrence of liquid collection at the reducing part of the pipeline. Concentric reducer, also known as concentric size head, is a type of steel butt welded pipe fittings. Shaped like a tapered joint, used to enlarge or reduce the diameter of the centerline. It is easy to transport slurries and abrasive slurries, suitable for corrosive operations, and also beneficial for use where different ratings and wear protection are required when transporting between flanges or pipes.
