We stock and manufacture different lined fittings to provide the nominal bore change when a pipeline size has to be stepped up or down. Our Concentric reducers are flanged at each end and are primarily used in vertical piping. Eccentric reducers are flanged in the same way but are made for use in horizontal piping, were the All the PTFE/PVDF/PFA/PP/FEP Lined Reducer in our range are made dimensionally to ASME B16.15 but can be supplied with a mixture of flange standards (e.g., ASME 150 flange at one end and ASME 300 at the other). While our standard range is made from lined carbon steel, we can also offer lined stainless steel piping systems if required.
