What are reducing flanges
Reducing Flanges
| Materials Used | Types | Uses |
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.
- Carbon steel
- Stainless steel
- Alloy steel
- Brass

- Bronze
- Aluminum
- PVC etc.
Types of Reducing Flanges:
Reducing flanges are normally provided as one of the following three types:
- Welding Neck
- Slip-On
- Threaded etc.

How to connect reducing flange?
To connect two sized pipes, the appropriate reducing flange is inserted between the two and bolted into place.
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.
