RADIOGRAPHIC TESTING (RT)
Radiography is an effective tool that requires very little surface preparation.
Moreover, many radiographic systems are portable, which allows for use in the field and at elevated positions.
Conventional radiography uses a sensitive film which reacts to the emitted radiation to capture an image of the part being tested.
This image can then be examined for evidence of damage or flaws.
The biggest limitation to this technique is that films can only be used once and they take a long time to process and interpret.
Radiographic Testing (RT) is a non-destructive examination (NDE) technique that involves the use of either x-rays or gamma rays to view the internal structure of a component.
In the petrochemical industry, RT is often used to inspect machinery, such as pressure vessels and valves, to detect for flaws.
RT is also used to inspect weld repairs.
Compared to other NDE techniques, radiography has several advantages.
It is highly reproducible, can be used on a variety of materials, and the data gathered can be stored for later analysis.
