浅析压力容器中法兰连接垫片密封泄漏原因

Analysis of Leakage Causes of Flange Connection Gasket Seal in Pressure Vessels

法兰连接是一种常见的可拆卸连接形式,普遍应用于生产实践.法兰接头的密封性能直接关系到整个压力容器的长周期运转情况,且法兰连接中垫片密封失效是引起泄漏的主要因素,主要讨论了法兰连接中易引起垫片泄露的因素以及相应的措施.

Flange connection was a common detachable connection, which was widely used in production practice. The sealability of the flange joint was directly related to the long-cycle operation of the entire pressure vessel, and the gasket seal failure in the flange connection was the main cause of leakage. The factors that cause gasket leakage in flange connection and corresponding measures were discussed.
