Radiographic Test (RT)
Qualitech offers the finest radiographic tests where the test objects are exposed to the varying transmission of ionizing radiation (X-rays, gamma rays) with the aid of photographic film or fluorescent screens to detect changes in density and thickness, and an image is produced. Our qualified staff then analyze and interpret the results in timely manner as required
Qualitech Plc. can provide radiographic services using a variety of rays in order to satisfy the needs of the customers:
1.1. Radiographic test by X-ray Suitable for products that require sharp image and quick testing with highest safety level
1.2. Radiographic test by Selenium-75 (Se-75) The quality of image is similar with that obtained by X-ray test. However, the machine is smaller, lighter and easier to move which render it suitable for works in confined space, work at height or in area where usage of radioactive rays affects the factory’s automatic control system.
1.3. Radiographic test by Iridium 192 (Ir 192) Using radiation with high penetrating ability, suitable for products whose thickness is equivalent to 6 mm. of steel and greater.
Radiographic Test is used to locate internal discontinuities in variety of products, such as casting, forgings and weldment. It provides precautionary awareness to customers for the best safety of material uses.
Benefit Radiographic Test (RT) :
– Can be used on most material
– Provide a permanent record (film)
– Give direct image of discontinuity
– Reveal discontinuities within a material
– Sensitive for volumetric discontinuity
– Disclosed fabrication error and check for correct assembly
