Where a pipeline size has to be stepped up or down, we have three different HiPerFlon lined fittings which provide this nominal bore change.
Concentric reducers are flanged at each end and typically used in vertical piping, eccentric reducers are again flanged and typically used in horizontal piping where the flat section through the reducer helps prevent pooling of liquid in the piping. Reducing flanges / plates can be used where space is tight around reactor heads or where large step changes in bore are required, they are certainly much more cost effective in large diameters.
Our range of reducers are manufactured dimensionally to ASME B16.5, however they can be supplied with a mixture of flange standards ie ASME 150 flange one end and DIN PN10 the other.
Like all our piping whilst our standard range is HiPerFlon lined carbon steel, we can also offer lined stainless steel piping systems.
