About Reducing Flanges

A reducing flange consists of a flange with a single specified diameter having a bore of a different and small, diameter. Except for the bore and hub dimensions, the flange can have dimensions of the large pipe size.

Reducer flange draws :

There are different types of reducing flanges including weld-neck reducing flanges, threaded reducing flanges, and slip-on reducing flanges.

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

How to connect reducing flange?

Weld Neck and Slip-On: Connect the flange sides that match the higher diameter of the pipe and complete the welding method. Repeat the welding method for the smaller size of pipe on the other side of the reducing flanges. Now both sizes of pipes are connected through the reducing method. Take enough care to make sure that the inside diameters of the pipes are properly aligned with the ID of the flange on both sides.

Threaded Flange: Initially connect any 1 size of the pipe by threading to one side of the flange. Make ensure that the pipe is inserted to reach the required depth inside the flange. Repeat the same method for the other side of the pipes.

In high-pressure and temperature applications, welding is done on the outer side of the pipe after threading to increase the strength of the joint.

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 can have dimensions of the largest pipe size.

Type of Reducing flanges

Metalica Forging Inc can design and produce the reducing flange as per request, we can supply the reducing flange in various types including weld-neck reducing flange, slip-on reducing flange, and threaded reducing flange, etc.

The number one feature of reducing flanges is that they are a highly economical way to make transitions between pipes of totally different sizes.

Uses of Reducing Flanges:

  • Reducing flanges are utilized in pipe-to-pipe connections.
  • Reducing flanges are a bit easiest to bolt up than non-reducing flanges.
  • They provide the most perfect solution when you need to connect various size flanges.
  • These flanges are readily available in all types and pressures.
  • Reducing flanges are mounted by welding, gluing, or clamping flanges of equal dimensions provided with totally different connecting pieces.
  • They offer the simplest and least costly method of mating 2 different sized flanges.

What is a Reducing Flange?

Reducing flanges are designed for once there’s a modification within the pipe size. The predominant flange (dimensions) matching the large pipe size (NPT) but having a small bore matching the smaller pipe size (NPT). These flanges normally come in slip-on, threaded, blind, and weld neck flanges.

They are available in all pressure classes and provide a good alternative to connecting 2 different sizes of pipe. This type of flange should not be utilized if an abrupt transition would make unwanted turbulence, such as at a pump.

Uses and advantages of Reducing Flanges:

Reducing Flanges provide the most perfect solution when you need to connect totally different sizes of flanges.
They offer a simple and most economical method to join 2 pipes of different sizes.

Mostly Available in various pressure classes up to #2500 class.

Reducing Flanges Applications and Uses:

  • Reducing Flanges used in Homes and buildings
  • Reducing Flanges used in Transporting materials
  • Reducing Flanges used in Automotive industry
  • Reducing Flanges used in Sewerage systems, industrial water lines, and water mains.
  • Reducing Flanges used in heating, ventilating, and air-conditioning equipment.
  • Reducing Flanges used in Plumbing
  • Reducing Flanges used in Food Processing Industry
  • Reducing Flanges used in Paper & Pulp Industry
