Reducing Flanges


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
Except for the bore and hub dimensions, the flange will have dimensions of the larger pipe size. Reducing flanges are normally provided as one of three types:
  • Welding Neck flange
  • Slip-On flange
  • Threaded flange
Uses 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.
