What is Gasket?

Gaskets are used to create a static seal between two stationary members of a mechanical assembly and to maintain seal under operating conditions which may vary dependent upon changes in pressures and temperatures. If it were possible to have perfectly mated flanges and if it were possible to maintain an intimate contact of these perfectly mated flanges thought the extremes of operating conditions, a gasket would not be required. This is virtually an impossibility either because of the size of the vessel and/or the flanges, the difficulty in maintaining such extremely smooth flange finishes during handling and assembly and Corrosion and erosionof the fanges surface during operations.
