REQUIREMENT OF PERFECT FLANGE SEALING


Fig.1.
FLANGES

Although the gasket material is considered the most important element in the system, it may fail to provide seal, because the other elements were not designed and constructed to make the best use of its properties. It is the contact pressure between the gasket material and the flanges that produce sealing. These pressure must be satisfactory for resisting the movements caused by those agents previously discussed (temperature, fluid pressure, fluid velocity and system vibration).
