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.

Designed for use in changing diameters in a piping system. A reducing flange consists of a flange with one specified diameter having a bore of a different and smaller, diameter.

Applications Of Reducing Flanges

Reducing flanges are used in pipe-to-pipe connections.

Reducing flanges are a little easier to bolt up than non-reducing flanges.

They provide the most perfect solution when you need to connect different size flanges.

These flanges are available in all types and pressures.

Reducing flanges are fixed by welding, gluing or clamping flanges of equal dimensions provided with different connecting pieces.

They offer the simplest and least expensive method of mating two different sized flanges.

What is a Reducing Flange?

Reducing flanges are designed for when there is a change in the pipe size. The predominate flange (dimensions) matching the larger pipe size (NPT) but having a smaller bore matching the smaller pipe size (NPT). These flanges normally come in blind, slip-on, threaded and weld neck flanges. They are available in all pressure classes and provide a good alternative to connecting two different sizes of pipe. This type of flange should not be used if an abrupt transition would create unwanted turbulence, such as at a pump.

Dimensions of Reducing Flanges

Draws of Reducing Flanges

Reducing Flange is reduced bore flange to facilitate connections with other flange smaller than the reducing flange. Often referred as Reducer Flange.

Reducing Flange can be fabricated using a reducing spool with concentric or eccentric reducer & desired flange at each end OR it could be a single flange with internal reduced bore to connect different sized fittings on either sides.

Reducing Flanges need to be described by bigger Inlet size & smaller Outlet size.

These Flanges can be either forged or can be directly machined from heat treated plates. Plate forming is preferable for smaller sized Reducing Flanges.
