Assessment of Defects and Microstructures for Evaluating Damage in Pressure Retaining Components

Reliable, safe and economical operation of pressure retaining components in various industrial plants depends on the importance given to quality assurance during fabrication and heat treatment of components and in-service performance assessment . Such an approach helps towards improved productivity, prevents unanticipated down time of plants, catastrophes etc. These objectives are satisfactorily met by adopting appropriate non-destructive testing and evaluation (NDT&E) procedures. We discuss in this paper our experience on development and application of a variety of NDT&E techniques for assessment of defects and microstructures in various pressure retaining components of industrial plants
