Expander flanges are a type of flange used in piping systems to connect pipes of different sizes. They are designed to gradually increase or decrease the diameter of the pipe, allowing for a smooth and seamless transition between the two pipe sizes.

Expander flanges typically have a hub that is larger or smaller than the pipe being connected, and a flange face that matches the size of the connecting flange. The hub of the expander flange is tapered, which allows it to gradually increase or decrease in diameter over a short distance.

Expander flanges are often used in situations where the diameter of the piping system needs to be changed, but a full transition piece or reducer would be too large or too costly to install. They are commonly used in applications such as oil and gas pipelines, petrochemical plants, and water treatment facilities.

One advantage of using expander flanges is that they can help to reduce turbulence and pressure drop in the piping system. This is because the gradual change in diameter helps to maintain a more consistent flow of fluid through the pipeline.

However, it’s important to note that expander flanges are not suitable for all applications. They can be more difficult to install and require precise alignment to ensure a proper seal. Additionally, they may not be suitable for high-pressure or high-temperature applications, where a more robust transition piece may be required.
