Kammprofile serrated gaskets are perfectly suited for secure sealing of flange connections in extreme operating conditions. They combine the specific properties of non-metallic gaskets [good elasticity to the flange surface] and metal gaskets [high stability and bursting strength]. The design allows high compression of the non-metallic layer, promoting low diffusion, and ensures that the serrated tips remain covered with non-metallic material, even in high surface pressure applications. In a compressed stage, the coverage of the serrated tip is still at approx. 0,1mm. Kammprofile serrated gaskets are described in DIN EN 1514-6 with regards to base body profiling, thickness and material of the layers. It complies with TA Luft 2002 [VDI 2440/2200].
Application: Gaskets for pipeline flanges, device and container flanges, pumps and valves. Widely used in the chemical and petrochemical sector, in conventional power stations and nuclear power plants, for steam generation and in device construction, especially wherever high temperatures and pressures have to be managed safely. Flange roughness of Rz <=80 μm is recommended. For higher temperatures >= 550 °C with non-metallic layer made from mica or silver and metallic carrier material made from 1.4828.
