Ring joint gaskets are solid metal gaskets and are used with stand high pressure and temperature, and they are employed where corrosive agents are presented. It is recommended that the gasket material be softer than the mating flanges. Some types of ring joint gaskets are activated when high pressure is presented; that means the higher the pressure, the better the sealability. To ensure a proper sealing the surface of contact between gaskets and flange has to be carefully processed.
