Pipe Reducer series

Concentric reducer, Eccentric reducer

Pipe reducers are key parts of your pipeline and are used to connect two pipes of different sizes, reducing the size of your pipe from a larger to a smaller bore, based on the inside diameter of the pipe. Reducers can be used either as a nozzle or a diffuser, depending on the mach number of the pipe's flow.

Adding reducers to your pipeline allows a change in the piping size to meet the hydraulic flow requirements of your system, or to adapt new piping to existing piping of a different size.

Whatever your requirements, we can provide you with alloy, carbon, or stainless steel reducers to make sure your piping system runs smoothly.

As China's leading manufacturer of eccentric and concentric pipe reducers, we guarantee that you're getting the best quality product, at a price you won't find anywhere else.
