CONDITION MONITORING
ABSTRACT
Condition monitoring of components and plants are of great importance for safe and reliable operation and for increasing productivity of plants. The challenges towards the condition monitoring can be successfully met by employing non-destructive evaluation (NDE) techniques. Vibration monitoring techniques are applied for periodic / continuous assessment of machinery parts and plants. Acoustic emission technique is used for leak detection and for structural integrity monitoring applications. Infrared thermographs are employed for condition monitoring applications in steel, electrical and petrochemical industries. Lubricant analysis by ferrography, and filed signature mapping are also used for condition monitoring applications. Here, applications of these NDE techniques could help to properly diagnose faults in plants components, enables taking timely decision about repair / replacement of components / plants, thus ensuring increased safety, reliability and productivity.
INTRODUCTION
The successful operation of structures / components during their entire life requires the implementation of a dedicated programme for condition assessment through in-service inspection (ISI) of all critical components of the plants / structures. The condition assessment through ISI and life prediction approaches enable uninterrupted operation, avoidance of unplanned shutdowns and taking decision on repair, up-gradation, modernization and replacement of necessary components for extension of the overall life of plants beyond their design lives. This is achieved through meticulous planning and incorporation of non-destructive evaluation (NDE) techniques which aims at detection and characterization of defects, stresses, corrosion micro structural degradations and dimensional changes that occur in components during service life, due to exposure to high temperature, pressure, static and dynamic loads, hostile environment etc.
