Concentric Reducer

A reducer allows for a change in pipe size to meet flow requirements or to adapt to existing piping. The length of the reduction is usually equal to the average of the larger and smaller pipe diameters. A pipe reducer is the type of pipe fitting which helps to join two pipes with varying diameters. The pipe reducers are available in a variety of materials as well as construction variation per the requirements of end users and also available in many dimensions.  

There are two types of reducer available in the industries these are as follows: concentric, and eccentric reducers. Eccentric reducers are used to maintain the services flow the same top level of pipe or bottom of pipe level in the piping system.  

Concentric Reducer

Concentric Reducers are used to connect the two pipe or tube ends to the same axis. Both connected pipe ends can be the same or may be different in bore size, as well, depending on the user requirement.

The main important is that they will provide an in-line conical transition between pressurized pipes of unmatched diameters of pipe. But the disadvantage of concentric type is that if installed concentric reducers in horizontally, there is always a possibility of creation of air or vapor pockets in the upper part of itself. The pipes cannot recognize what the outside configuration of the pipe reducer looks like. The pipe flow is affected by the inside diameter conical transition configuration which can be axially moved and externally reconfigured to provide for more economical reducer fittings. Thus, concentric types fitting connect pipes of unequal size as well as eccentric but have a common centerline. In other words, the Concentric reducer, reduction of the pipe size is achieved by decreasing the diameter of the fitting at a constant rate over a specified length, maintaining symmetry around the fitting. It is a type of pipe fitting to connect the different pipes of different diameters that join pipes in the same axis. Concentric reducers are designed with the small and large diameters on opposite ends and joined by a cone shaped transition section.
