| Abstract: | On the high temperature test device of gasket performances, experimental research on thermal sealing performance is conducted for spiral wound gaskets with flexiable graphite filler, the relation curves showing sealing performance of gaskets vs. temperature and regression equation are obtained. The result shows that this type of gasket has excellent sealing performance, leakage rate increasing with increase of temperature as exponent function of temperature conforms to the equation of the porous media model. |
