REDUCING FLANGE

Our Reducing flange are designed in compliance with international quality standards. Available in all types and pressure, these flanges are widely used for pipe-to-pipe connections. The reducing flange includes a flange with one specified diameter having a bore of a different and smaller diameter. Except for the bore and hub dimensions the reducing flange will have dimensions of the larger pipe size. To increase the size of the flange, these are used at the outlet side of the expansion joint. Also provides steel reducing flanges and stainless steel reducing flanges. It is the most economical method to make a transition in size.

Uses of reducing flanges:

  • 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.

Type of reducing flanges: welding neck, slip-on, threaded.

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.
