Prognostics & Health Management of Swing Type Check Valves

Abstract — Prognostics and Health Management is emerging as new paradigm to address issues related to enhancing the safety as well as availability. The enabling technologies are state-of-the art in on-line monitoring or periodic surveillance tools and availability of degradation assessment approaches that provide a framework for residual life assessment of component. Availability of physics of failure or mechanics of failure models and intelligent tools are vital for implementation of a prognostics and health management programme. This paper presents an approach for prognostics and health management of Check valves. The results shows that this approach is promising to detect in advance the incipient failure such that maintenance programme can be initiated to improve the availability as well as safety. Even though this approach addresses modelling of swing type of check valves, the models can easily be adopted for other type of check valves als
