Concentric Reducers

Concentric reducers are used to reduce the flow or the size of a pipeline. Either end of the concentric reducer is of a different size and is manufactured to suit nominal bore pipe and its relevant scheduled wall thicknesses. The component has the same centre line throughout its length.

At Alexander Comley we press our own concentric reducers from seamless European pipes.
