Reducing Flange
A Reducing Flange connects two pipes of different diameters within a single flange, combining the job of a flange and a reducer fitting into one forged component. This removes the need for a separate reducer and an extra weld joint, saving installation space and reducing overall project cost.
At Royal Steel India, we manufacture and supply premium-quality Reducing Flanges in a wide range of size combinations, pressure classes, materials, and international standards. Our flanges are precision-engineered to deliver a strong, leak-proof connection at the size transition point.
A Reducing Flange has a bore sized to a larger nominal pipe size on the pipe-connecting side, while the bolt circle, gasket face and hub match a smaller flange size on the mating side. It is most commonly made as a weld neck or slip-on flange, and can be supplied with most standard face types, including raised face and ring type joint.
Reducing Flanges are widely used wherever a pipeline steps down to a smaller size before connecting to a valve, instrument or piece of equipment.

Frequently Asked Questions
What is a Reducing Flange used for?
A Reducing Flange is used to connect two pipes of different sizes at a single point, without needing a separate reducer fitting welded into the line.
How is a Reducing Flange different from a standard flange plus a reducer?
A Reducing Flange combines the flange and the size transition into one forged component, saving a weld joint, installation time, and space compared to bolting a full-size flange to a separate reducer.
Which flange types are available as reducing flanges?
Reducing flanges are most commonly available in weld neck and slip-on styles, and can be manufactured to most standard face types including raised face and RTJ.
What materials are available for Reducing Flanges?
Reducing Flanges are available in Stainless Steel, Carbon Steel, Alloy Steel, Duplex Steel, Nickel Alloys, Inconel, Monel, Hastelloy, Titanium, and other special alloys.
