Reducer are widely used in piping systems to connect pipes of different diameters. They play a crucial role in maintaining proper flow and ensuring efficient fluid transportation. There are two types of reducers: concentric reducers and eccentric reducers.

 

 

A concentric reducer is cone-shaped and has an axis of symmetry. It has large and small openings that align with the centerlines of the connecting pipes. The reduction in pipe size is uniform, resulting in a reduction in both the diameter and the thickness of the pipe wall.

 

 

An eccentric reducer, on the other hand, is similar in shape to a concentric reducer but has an off-center alignment between the two openings. This results in an offset between the centerlines of the inlet and outlet pipes. Eccentric reducers are primarily used to prevent the accumulation of gas pockets or condensate in horizontal piping systems where drainage is necessary.

 

 

The key function of a pipe reducer is to facilitate a smooth transition between pipes of different sizes while maintaining the flow capacity of the piping system. It helps to avoid turbulence, pressure drops, and excessive resistance to flow. Pipe reducers are commonly used in various industries, including oil and gas, chemical processing, water treatment, and HVAC systems.
