The characteristic of blind flanged bolted joints with full-face gaskets
- Yamanashi Univ., Kofu, Yamanashi (Japan). Dept. of Mechanical Engineering
In this paper, the characteristics of blind flanged bolted joints with full-face gaskets such as the contact stress distributions and the variation of axial bolt force are analyzed using axisymmetrical theory of elasticity. The effect of Young`s modulus of gaskets, the gasket thickness and the bolt pitch circle diameter on the contact stress distribution are clarified by the numerical calculations. In the experiments, the contact stress distributions were measured by sensitive films when the gasket is asbestos. Variations of axial bolt force are measured using strain gages. The internal pressure is observed when the internal fluid starts to leak. The numerical results are in fairly good agreement with the experimental results. Discussions are made on the sealing performance of gaskets used in these experiments.
