Study on Effect of Gasket Stress Distribution on Bolted Flanged Connections

Abstract:

The gasket stress distribution was analyzed by finite element method (FEM). The leakage of bolted flanged connections was predicted based on gasket stress distribution, and the results were investigated and compared with the experimental results. The effect of gasket stress distribution on connection leakage was studied. The results indicated that the flange rotate enlarged along with increasing of bolt load, and the inhomogeneity of gasket stress distribution improved, and then the difference value of average gasket stress and maximum gasket stress expanded. The maximum gasket stress located at the gasket outer periphery is found to be a key parameter that controls leakage.
