The metal gasket sealing performance of bolted flanged with fem analysis

Abstract

There is a wide variation of flange style and configuration, but only four types of facing are widely used, which are raised face, flat face, ring joint facing and lap joint flange. Corrugated metal gaskets 400MPa-mode has better performance than gaskets 0Mpa-mode for flat face flange type. In this study we investigated the performance of corrugated metal gasket 400MPa-mode for three types of flange facing which are raised face, flat face and combination raised-flat face. The finite element method employed to analysis the effect of different types of flange on contact width and contact stress in relation with axial force of corrugated metal gasket. The result shows corrugated metal gasket 400MPa-mode give good performance for all type of flange face.
