Ring Joint Gasket
Ring joint gaskets are metallic sealing rings suitable for high pressure and high temperature applications and are fitted in ring groove type flanges. They are widely used in the oil, gas, petrochemical industries and in high pressure valves. Choice of material may be determined to suit higher temperatures and aggressive media. Ring type joint gaskets are designed to seal by initial line contract or wedging action between the mating flange and the gasket. By applying pressure on the seal interface through bolt force, the softer metal of the gasket flows into the micro fine structure of the harder flange material, creating a very tight and efficient seal.
