NDT Technology Overview


Product Life Cycle is dependent upon the quality of the product for which it has been designed. To validate the product quality one requires carrying out destructive or non destructive testing. While destructive testing is expensive, Non Destructive Testing (NDT) is economical as compared with its counterpart. Traditional methods based upon Film Radiography, Ultrasonic, Eddy Currents, and Dye Penetrant Testing have been used in the industry since four decades. With the evolving technology the above methods have become refined leading to a further reduction in NDT costs.

CIT's Digital Radiography technology is one of the methods that has had an impact on the product inspection process as, it is economical, reduces project time scales and is eco friendly. This is attributed to the facts that it reduces radiation energy by 50% and exposure time by 60 to 70%. The Digital Radiography provides a new innovative method that replaces X-ray films, darkroom processing and conventional archives with computer systems, electronic archiving and x-ray capture using direct or reusable digital imaging plates.

The flexible imaging plates can be used just like ordinary films in jackets and can be placed inside and outside of the product under inspection. These plates are exposed in a similar manner to standard radiographic setup but with reduced radiation energy and exposure time. Further, the technology has been proven to work with Ir192, Se75, x-rays, Yb169, and Co60. Also, the images generated by Digital Radiography meet with the overall radiography inspection standards of pipelines, pressures vessels etc. CIT's Digital Radiography technology is field portable for site radiography and can have a payback period of 6-9 months against specific projects.

NDT test houses can benefit significantly and improve their profitability.
