Flange Gasket for Gas Turbine Exhaust Collector and Ducting

Thermopack is a flange gasket specially developed for Gas Turbine Exhaust Ducting.


The gasket is manufactured from heat resistant steel alloys.

The gasket concept is made to secure that correct flange clamping load is achieved, by the introduction of a spacer washer in between the flanges


The spacer washer prevents crushing of the gasket, being a typical problem for traditional ceramic fibre and glass fibre gaskets.

The spacer washer also secures a stiff bolt connection, meaning steel to steel contact through the bolt connection, allowing for a correct pre-tension of the bolt.
