EXPANSION FLANGES
A purpose designed seal for wall, floor and ceiling penetrations of process piping in food and beverage plants or any applications where a waterproof hygienic seal is required.
Design allows for lineal expansion and contraction of pipework whilst maintaining an intrinsic seal to prevent ingress or water etc. to penetrated material. (See detail 1).
The flange can also be adapted to accommodate Stream Pipe or Non-Standard tube diameters by adding a Teflon or heat resistant liner. (See detail 2).
