Metals & Alloy Testing

Metal and Alloys
Metal and Alloys are integral to Industrial growth. be it in construction of structure, building of machinery or processing raw materials into finished products. Equipment and Components in giant industries like Power Plants are exposed to different operating conditions and exhibit aging effects of various degrees depending on the service severity and period. Working with damaged machinery not only a effects the performance and output. but also involves risk of catastrophic failure. Such parts and components need to be repaired or replaced at the appropriate time avoiding in scheduled plantoutages. MODI LAB plays an important role in analysing and certifying all types of components of Metal and Alloys by conventional methods like Chemical/Mechanical, Non Destructive Testing and by using sophisticated instruments.

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 eto. n 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 line 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.
