Reducing
Flanges
Reducing flanges are designed for use in changing diameters in a piping
system. A reducing flange comprises 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. These flanges are used at the outlet side of the
expansion joint to increase the size of the flange. This is considered
to be an economical method to make a transition in size.
Buying Tips Certain factors that buyers should consider
before buying reducing flanges are as follows:
- Size
- Type
- Face type
- Style
- Length
- OD
- Pressure Rating
- Thickness
- Materials (tested for corrosion resistant)
- Tested and verified for durability, accuracy and precision
etc.

Materials used:
- Carbon steel
- Stainless steel
- Alloy steel
- Brass
- Cast Iron
- 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.
