Concentric Reducers are used to join pipe or tube sections on the same
axis. They provide an in-line conical transition between pressurized
pipes of differing diameters. A pipe reducer can be a single diameter
change or a multiple diameter change. 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 reducers connect
pipes of unequal size but have a common centerline. In other words, it
is a type of pipe fitting with different size ends to join pipes of
different diameter that joins pipe sections on the same axis.
Factors to consider are as follows:
- Whether seamless fittings or welded fittings or forged
- Size and dimension
- Wall thickness
- Material of construction
- Forming type: press-forming for metal reducers
- Reducers: hot forming for carbon steel reducers
- Tested for durability, accuracy and precision
Concentric reducers are designed with the small and large diameters on
opposite ends and joined by a cone shaped transition section. They are
available in both seamless and welded construction.
- Stainless steel
- Carbon steel
- Alloy steel
- Alloy titanium
- Cast Iron

Get the measurements of outer diameter (OD) and inner diameter (ID) ,
height (H), and the total dimension (T1, T2).
Uses of concentric reducers:
Some uses of concentric reducers are as follows:
- Concentric reducers will transition gracefully between the piping
and the pump.
- The concentric reducers help in transporting slurries or abrasive
- They are useful in services where cavitation is present.
- When transporting between flanges or pipes of different ratings
and wear protection is necessary, concentric reducers are ideal.
