The pipe reducers are divided into two types: concentric reducer(Con reducer) and eccentric reducer (Ecc reducer).

Concentric Reducer (Con Reducer)

Concentric Reducer (Con Reducer)

The size of the circle in the same line head is called Concentric Reducer. Usually adopted for reducing the forming process of pressing, expanding to suppress or reducing and expanding, to certain specifications of the reducer and stamping can be applied.

Concentric Reducers are used to join pipe or tube sections on the same centerline. They provide an in-line conical transition between pipes of differing diameters. Comparing to the eccentric reducer, the concentric type reducer is easier and low cost to produce.

The shape of the concentric reducer like a / \, it is used a lot in the vertical piping systems. Because of the diameter change the pipes, it will bring the change in flow of fluid or other abrupt.
