A Kammprofile gasket is made of a solid metal core that can be made with regular gasket materials. These materials are carbon steel, 304 stainless steel, 316 stainless steel (if you need to go to higher temperatures), and other high-temperature materials such as Hastelloy and Inconel.
The gasket has machined serrations that look like grooves into the gasket material. This is where we get the term grooved metal gasket from. These serrations are made to put a facing material on the sealing surface.
The facing material (filler material) is often typically a soft facing material such as graphite facing (flexible graphite is what manufacturers call it). Other non-asbestos fillers include mica (high-temperature applications), PTFE and other sealing materials.
While they don’t need a guide ring (like the outer ring of a spiral wound gasket), we like to see them on the gasket as it helps the assembler center the gasket during assembly. This can be adapted to this gasket, but we only see the graphite facing in petrochemical applications.
The guide ring will generally be loose-fitting. It allows the solid metal core of the gasket to grow during thermal expansion.
The Petrochemical and Chemical industries benefit too, as the gaskets are used in applications where high pressures and temperatures are maintained and consequently high bolt loads need to be controlled.
