Concentric Reducers

The Concentric Reducers are available in variety of shapes and dimensions to suit major pipeline installation requirements in industries. This is one of the most commonly used industrial pipe fitting for adapting different pipe sizes in a pipeline system. It is primarily used to connect two pipes with different diameters.

Made from best grades of stainless steel, these reducers are available in a wide range of sizes, wall thicknesses and pressure ratings to choose from according to the pipeline. Ensuring an in-line conical transition between different diameters of pressurized pipes, these concentric reducers join the pipelines on the same axis.The construction of these reducers is done by joining the small diameters and large diameters on opposite ends of cone shaped transition section. Find application in petrochemicals, sugar mills & distilleries, steel plants and cement & construction industries, the reducer has separate inlet and outlet ends.
