There are two types of reducers: concentric reducers and eccentric reducers. The shape of the eccentric reducer is asymmetric, and the centers of the two ends are offset from each other. This design allows for gradual transitions between pipes of different diameters, while changing the elevation or position of the pipes. Eccentric reducers are usually used in situations where vertical or horizontal adjustment of the pipeline is required to ensure optimal flow rate. They can be applied in industries such as oil and gas pipelines, sewage treatment, chemical manufacturing, and wastewater management.

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.

 

 

Reducers are suitable for chemical, petroleum, natural gas, pharmaceutical, food and other industries, and are widely used in pipeline systems under complex conditions such as high pressure, high temperature, low temperature, strong corrosion, etc. Especially in highly automated production lines and engineering projects, reducers are used more widely.
