- 論文の詳細を見る
The leakage of inner fluid through the gasket seat is influenced by the gasket material, inner fluid, the fastened force of the bolts, etc. Especially, the pressure distribution on the gasket seat is considered the most important factor for the leakage. In this report, the effective seating width of the gasket was analyzed by FEM and was compared with the values given in JIS and ASME Standards. Moreover, the minimum number of bolts required to get almost uniform pressure on the gasket seat was determined. The effect of the number of bolts on the flange stress was also analyzed and discussed.
