Kammprofile gaskets are our best friend for heat exchangers and other custom flanges. It is strong and difficult to break during assembly, they work under high temperature, and high pressure, and can withstand large bolt loads. They are much better than double jacketed gaskets, corrugated metal gaskets, and large diameter spiral wound gaskets.
Large diameter spiral wound gaskets will bend and pop out. In contrast, a small amount of graphite appears on the Kammprofile gasket. Kammprofile washers are also super resilient to radial shear. Probably the best part about these gaskets is how easy it is to adjust the area of the gasket to create a better seal.
Kammprofile gaskets can be put into flanges in many different configurations, such as flat face flanges or even muffler joints in vehicles, and some manufacturers even offer conversion gaskets for ring joint gaskets for raised face flanges.
The disadvantage of Kammprofile gaskets is that they are stiff and more susceptible to flange face defects. Therefore, we need to ensure that our flange sealing surface has minimal dents and scratches and that it meets the PCC-1 Appendix D Flange Surface Flatness Tolerances.
