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.
Kaxite Ring Joint Gaskets or RTJ’s are made to withstand extreme pressures and temperatures while being used in highly corrosive environments. They meet or exceed API-6A specifications and are available in soft iron, low carbon steel, SS 304, SS 316 and other exotic alloys for specialty applications.
