Whether it is shipbuilding or its maintenance operations, NDT Radiography plays an important role in investigating the state and quality of welds in plates, welds, valves and fabricated structures. Usually gamma radiography is performed to investigate the welds and materials, which requires reduced time access prior to radiography being conducted. Another drawback of gamma radiography is that it requires isolation of inspection place by setting up barriers to prevent staff and personnel from being exposed to harmful radiations. In addition, exposure times are long due to thick material walls that are to be inspected.
CIT's Digital Filmless Radiography - AN ALTERNATIVE
With CIT's Digital Filmless Radiography the world of NDT radiography is being revolutionized. The use of Digital Radiography is resulting in reduced cost of ownership due to the following benefits:
> Reduced exposure times
> Reduced dose of radiation isotope as compared to conventional film radiography
> Replacement of radiograph films, chemicals and wet chemistry with flexible reusable digital imaging plates
> Use of computers with readers, scanners and high resolution monitors
> Electronic archiving of images, associated records and radiograph films to fulfill the inspection management
CIT's radiograph image quality matches the radiograph film quality and meets with the ASME V, CEN 1435 & EN473 Radiographic Standards and Qualifications.
The key need that Digital Radiography fulfils is the significant reduction in cost of ownership with ROI of 6 months to 18 months and increased production throughput.
