  • Gasket for flange connections
    Patent number: 6962349
    Abstract: A flat gasket for flange connections has a leakage rate below the limit value of 1*10?5 kPa*1/(s*m). The gasket assembly has a thick, areal, pressure-resistant core formed from at least one layer of graphite foil with a base weight of at most 1500 g/m2, or a multilayer sandwich of such graphite foils and metal interlayers. The core is embedded between two metal foils, and the surfaces that are remote from the core are covered by covering layers of graphite foil with a base weight of at most 350 g/m2. A ratio of the base weight of the graphite foil of the covering layers to the base weight of the graphite foil of the core lies between 1:3 and 1:7.
    Type: Grant
