Non Destructive Testing (NDT)

The Company has complete in house facility to execute various jobs related to non-destructive testing

Non Destructive Testing (NDT) has been traditionally used for Flaw characterization and measurement of Residual Stress. Any Engineering component, when put in service, is designed to last for definite period referred to as Design Life of the component. There are many factors, which adversely affect the design life and lead to premature retirement of the component from service. Such Factors include unanticipated stresses (residual service), operation outside designed limits (excessive temperature, load cycling), environmental effects, degradation of material properties in service etc.

On the other hand there can be some favorable factors, which result in lesser degradation of the components than expected in its design life. Such factors include use of minimum value of Mechanical properties in design, factor of safety in design, conservative operation of unit, inaccuracy in data extrapolation, overestimation of corrosion effects etc.

Here lies the importance of Residual Life Assessment (RLA) and Plant life Extension (PLEX) since constructing a new plant is always much more expensive than extending the life of the Existing plants. In this regard, non-destructive evaluation provides all the vital inputs necessary for assessment of structural integrity. The NDT study is of National importance since many operating powers, chemical and petrochemical plants are approaching their end of design life.

NDT is the field of civil engineering where structure constructed evaluated without damaging it. Quality of civil-engineering structure depends on good construction practices & further continuous repair and maintenance preserve the construction quality. Our experts to evaluated civil structure on site conducted the various NDT tests and few tests were conducted at our laboratory.
