Gaskets are mechanical seals, usually ring-shaped, which seal flange joints. Also, a Gasket will vary by construction, materials and features.
Commonly used gasket are non-metallic (ASME B 16.21), spiral-wound (ASME B 16.20) and ring-joint (ASME B 16.20). A Non-metallic gasket are used with flat- or raised-face flanges.
Also, Spiral-wound type gasket are used with raised-face flanges, and ring-joint gaskets are used with ring-type joint (RTJ) flanges. Stress develops between an RTJ gasket and the flange groove when the gasket is bolted to a flange, leading to plastic deformation of the gasket.
