What Is An Expansion Flange Used For?

Expansion Flange’s are technically not in the typical flange family. The purpose designed is to secure tube or piping in wall, floor and ceiling penetrations.

 

These flanges are commonly used in food or beverage plants, cool stores or any applications where a waterproof hygienic seal is required. The design of this flange allows for linear expansion and contraction of pipework whilst preventing ingress or liquid to penetrate. This helps to keep the area tidy so that nothing can enter into the cavity of the wall or through the wall.

 

We stock expansion flanges to accommodate imperial, nominal bore, and metric tube sizes. Non-standard tube diameters can be adapted by adding a custom rubber liner.

 

The expansion flange is made up of three different parts. The outside structure of the flange which sits on the outside. The seal on the inside and then the backend plate that sits up against the wall and holds the seal in place.
