Oval Ring Joint Gasket, SS 316, ASME B16.20, R77, 24 Inch

The primary function of 316 oval gaskets is to fill microscopic gaps between mating surfaces, preventing leakage of fluids or gases. Under high-temperature and high-pressure conditions, metal materials maintain stable performance without deformation or failure. For example, in the petrochemical industry, pipeline systems often handle high-temperature and high-pressure media, where metal oval gaskets play a critical role‌.

Why choose an oval shape over other designs? The oval geometry allows for more uniform stress distribution under pressure, reducing the risk of localized overload. In certain flange connections, the oval shape better accommodates non-circular bolt hole patterns, enhancing installation convenience and sealing reliability‌. In contrast, circular gaskets may rotate or shift under high pressure, while the oval structure avoids this issue through its inherent geometric properties.

The radial self-sealing effect of oval 316 ring gaskets (a standard type R) relies on contact with the inner and outer surfaces (mainly the outer side) of the flange's trapezoidal groove, achieving sealing through compression‌.
