The Effect of Flange Roughness on Leakage Rate

Leakage rate tests were performed on two types of type 304 stainless steel gaskets. One type had asbestos fillers and the other had graphite fillers. The gaskets were tested at roughnesses of 125, 250, 500, and 1000 micro inches, AARH.

Regression analysis was performed on the test data to obtain comparison curves for the effect of flange surface on each type of gasket.
