Reducing Flange Manufacturers, Supplier and Exporter in India

Reducing flanges, otherwise called reducer flanges, have an opposite function than expander flanges seen above, i.e.they are used to decrease the bore of a pipeline.
The bore of the run pipe can be safely reduced by only 1 or 2 sizes (otherwise a solution based on the combination of a butt weld reducer and a standard flange has to be used). Reducing flanges are available in most sizes and material grades, and are not generally available from stock. Reducing flanges follow the same considerations in terms of specifications, sizes and material grades as expander flanges. The last type of forged product that resembles the shape of a flange is the so-called spectacle blind: while not properly a flange, a blind (or a ring spacer or spade) is used in between pipes to isolate the pipeline mechanically and in a very easy way. More details are provided in another section of our Wiki for piping.

Frequently Asked Questions

Most frequent questions and answers

What is a Reducing Flange, and how does it work?

A reducing flange is a type of flange that is used to connect two pipes of different sizes together. It is used when a pipe with a larger diameter needs to be connected to a pipe with a smaller diameter. The flange is typically made of metal and has a hole in the center that is the same size as the smaller pipe, with the larger pipe fitting around the outside of the hole. The flange has two different bore sizes, one for the smaller pipe and another for the larger pipe. The flange is then bolted to both pipes to secure them together and create a leak-proof seal. This type of flange is commonly used in plumbing, HVAC and other industrial systems where there is a need to connect pipes of different sizes.  

What materials are reducing flanges made from?

Reducing flanges are typically made from various types of metals, such as carbon steel, stainless steel, or alloy.

What is a Reducing Flange, and how does it work?

 Reducing flanges are typically attached to pipes using bolts or other fasteners.

How are reducing flanges attached to pipes?

Reducing flanges are typically made from various types of metals, such as carbon steel, stainless steel, or alloy.

What are the benefits of using reducing flanges?

Reducing flanges allow for the connection of pipes with different sizes, which can be useful in situations where pipes with different diameters need to be connected. They also provide a secure and leak-proof seal between the pipes.

Are there any specific codes or regulations that need to be followed when installing reducing flanges?

 Yes, different codes and standards must be followed when installing reducing flanges, such as ASME B16.5, MSS SP-44, EN 1092-1, and API 605.
