Reducing flanges are a specialty flange that are most often used on projects that require the fitting together of different sized pipes.
Reducing Flanges are suitable for changing line size, but should not be used if abrupt transition would create undesirable turbulence, as at pump connections. A reducing flange consists of a flange with one specified diameter having a bore of a different and smaller, diameter.Except for the bore and hub dimensions, the flange will have dimensions of the larger pipe size.
There are several types of reducing flanges including weld-neck reducing flanges, slip-on reducing flanges and threaded reducing flanges and so on. The number one feature of reducing flanges, is that they are a highly economical way to make transitions between pipes of different sizes.
