Radiography Testing

Radiography Testing

Radiography testing (RT) is a non-destructive method that uses X-rays or gamma rays to inspect the internal structure of materials and components. It is highly effective for detecting volumetric discontinuities such as porosity, inclusions, and cracks.

Service Details

In radiography testing, a controlled radiation source is directed toward the test object. A detector or film placed behind the object captures the radiation that passes through. Areas with internal discontinuities allow more radiation to pass through, appearing darker on the radiograph. Dense areas or defects appear lighter.

This method provides a permanent visual record of the inspection, which can be reviewed and archived for future reference.

Common Discontinuities Detected by Radiography Testing

• Porosity – Small gas pockets within the material

• Slag inclusions – Non-metallic materials trapped during welding

• Cracks – Linear discontinuities caused by stress or fatigue

• Lack of fusion – Incomplete bonding between weld layers

• Incomplete penetration – Weld metal that does not fully penetrate the joint

• Corrosion and wall thinning

Applications

Radiography testing is used in:

• Pipeline girth weld inspection

• Pressure vessel and storage tank examination

• Casting and forging quality control

• Aerospace and automotive component inspection

• Power plant piping and boiler tubes

Our Radiography Testing Capabilities

Our facility is equipped with:

• X-ray generators for thin to medium thickness materials

• Gamma ray sources (Iridium-192, Selenium-75, Cobalt-60) for thick and field applications

• Digital radiography (DR) and computed radiography (CR) systems

• Darkroom and film processing facilities

• Radiation safety equipment and dosimeters

All radiography testing is performed by ASNT Level 2 certified technicians following ASME, ASTM, and API standards. Safety protocols strictly adhere to national and international radiation safety regulations.
