RT Enclosure at Bangalore in India


Trinity NDT is a unique NDT Lab of its kind for Industrial testing in India. Designed to meet requirements of AERB, it is one of the best NDT lab with enclosure facility. To ease in handling, 5T EOT crane for carrying heavy components inside Radiography enclosure. With this, it is never difficult to get your x-ray testing. The enclosure can operate at 100 Curie gamma rays. Cameras carry sources under safe conditions. X-rays provides extra quality of testing.

If any door of a radiographic enclosure is opened, x-ray machine is automatically switched off and cannot be switched on while the door is open. Also has emergency alarms and warning lights for safety.

Dark Room for X-ray Film Processing


Dark room processing of X-ray film is critical. Film artefacts are the result of inappropriate film processing. Also, quality of x-ray film image depends on quality of film processing. Therefore, we process films at the our darkroom under safelight. Selection of X-ray film quality depends on customer needs. For example, AGFA D4 and D7 film. However, based on need, we can also do testing using any other quality x-ray films.

Onsite Radiography | In-house RT Enclosure


Majority of our radiography is on RT testing of Castings and Welds. For example, we do x-ray of steel and aluminium castings to find flaws. Also X-ray of weld joints on pressure vessels, valves and pipelines. Both onsite and offsite NDT testing possible based on needs of customers. Also, now we can provide Composite X-ray testing as well.

X-ray Testing of Castings and Welds


With decades of experience, our Radiographers can do RT inspection of heavy castings and weld joints. For X-ray film interpretation of castings we use reference Radiographs ASTM E446. Similarly, Welding Radiography reference standards are available for weld x-ray testing. In other words, we bring you trusted results so that you will know the quality of your castings and weld joints.

ASNT Level III Services | Radiography testing


The test results are most reliable under able guidance of experts. Considering the importance of quality, the in-house ASNT NDT Level III approves the procedures and techniques before starting the testing. Can also support the customers on preparing Radiography procedures for testing of casting and welds. Download free NDT procedures and test report formats in pdf. If you need NDT consulting services contact us. Know more about the team.

Safety In Testing


Whether it is onsite testing or offsite testing, safety is paramount in Radiography testing. The RT testing is under the close supervision of Radiological Safety Officer – RSO & Site Incharge to ensure safety round the clock. BARC Certified Radiographers will take exposures. Our Radiographers have right blend of theory and practical exposure mended by in-house RT Level III to handle critical RT testing with greater efficiency.

AERB, Mumbai is the regulatory body in India. For onsite radiography, upon application, AERB issues prior approval. Contact us well in advance for your onsite x-ray testing of welds and castings.

A team of RT Level IIs leaded by ASNT NDT Level III will perform x-ray film Interpretation. Know more about the Team at Trinity NDT.

What is the principle of RT testing?


Radiography is an NDT Method to test materials for internal flaws. The process is much suitable for finding defects and also used for testing assembled components.

RT testing is based on differential absorption of penetrating radiation. The component absorbs part of Gamma Rays or x-rays. Because of differences in material density and variations in thickness of the part, or differences in absorption characteristics, different portions absorb different amounts of radiation. Unabsorbed radiation passes through the part. Finally, film or electronic device records the images to identify flaws. In other words, radiography is a process that produces a permanent image on film or digital form.

Radiography testing applications


Radiography inspection detects defects in a component or assembly that exhibit a difference in thickness or physical density as compared to surrounding material. In general, it can detect only those features that have an remarkable thickness in direction parallel to the radiation beam. Therefore, the ability to detect planar discontinuities such as cracks depends on orientation of weld or casting during testing. Also finds, Flaws such as voids and inclusions, which have measurable thickness in all directions. In general, RT detects flaws are that exhibit a 2% or more difference in absorption. Testing is more effective when the flaws are not planar. As the test results are permanent, RT is vital for testing quality of welds, valves and castings.

Other applications for RT, includes testing of semiconductor devices for cracks, broken wires, unsoldered connections, foreign material and misplaced components.
