Types of gaskets. Non-Metallic gaskets are usually composite sheet materials are used with flat-face and raised-face flanges in low Pressure Class applications. Non-metallic gaskets are manufactured from arimid fiber, glass fiber, elastomer, TeflonÂ® (PTFE), graphite etc.. Full-face gasket types are suitable for use with flat-face flanges. Flat-ring gasket types are suitable for use with raised face flanges. ASME B16.21 covers types, sizes, materials, dimensions, dimensional tolerances, and markings for non-metallic flat gaskets.
Flange gaskets, regardless their manufacturing material and type, fill the spaces and the irregularities existing on the faces of the mated flanges when they are bolted and tightened together. Gaskets generate a very strong seal that prevents fluids and gases from leaking out of the flanged connection. The installation of gaskets between flanges is a mandatory requirement, i.e. it is not possible and safe to tighten flanges without using gaskets inbetween. There are several types of flange gaskets.
