Flange surface roughness has a great influence on sealing effect, especially when using non-soft gasket, the roughness of sealing surface is one of the main causes of leakage.For example, turning flange surface knife grain is spiral, the use of metal gasket, European standard flange wholesale, if the roughness value is large, gasket can not block the spiral groove formed by the knife grain, under the action of pressure, the medium will leak out along the groove.For soft gaskets, flange surface is too smooth but unfavorable, because the occurrence of interface leakage resistance decreased.Therefore, different gaskets, required flange surface roughness is not the same.
