A ring gasket is a precision-engineered sealing component used primarily in high-pressure and high-temperature flange connections, particularly in the oil, gas, petrochemical, and power industries. It is typically a solid metal gasket, shaped in a circular form, and designed to fit precisely into a machined groove on ring-type joint (RTJ) flanges. Ring gaskets are made from various metals such as soft iron, carbon steel, stainless steel, or more exotic alloys like Inconel, Monel, and Hastelloy, chosen based on the application’s pressure, temperature, and chemical compatibility. These gaskets create a metal-to-metal seal by deforming slightly under high bolt load, offering a robust and reliable seal that resists blowout in harsh conditions. Their durability and high sealing efficiency make them essential for critical applications involving steam, oil, gas, and corrosive media.
