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.

We also supply and stock:
- Billets cut from round bar
- BSP/NPT/SW Fittings
- ASME SA269/249/270/A213 tubes
