Reducing Flanges

Reducing Flanges are specifically designed for use in changing diameters in a piping system. The flanging system comprises of one specified diameter having a bore of a different and smaller, diameter. Except for the bore and hub dimensions, the reducing weld neck flange will have dimensions same as the larger pipe. These reducing pipe flanges are generally used at the outlet side of the expansion joint to increase the size of the flange. This is considered to be an economical method to make a transition in size. Reducing Flanges
