Residual Life is that time period during which a material especially an engineering material shall retain the fitness characteristics that are important for its services. Residual Life Assessment studies are generally conducted for Power Plant components and several other machines which are subjected to fatigue and creep loading conditions. For conducting RLA studies, the methods and techniques should be selected carefully. Identification of the failure prone areas and their treatment is very essential for preventing accidents. The equipment which need RLA studies include boilers, piping, pressure vessels, storage tanks, pumps, turbines, compressors, etc.
It is necessary to keep equipment in efficiently operating condition and maximize the life of that equipment. There are different types of components in equipment which require a routine inspection to check their proper working conditions. By carrying out inspection, all the information related to the degradation which can affect the service life of that equipment is obtained which will help to provide an early warning to take appropriate actions before facing the failure. After the whole study and past experiences, suitable methodologies can be incorporated to avoid such issues in future which may cause expensive downtime problem.
