Radiography Testing

Radiographic Testing (RT) involves the use of either x-rays or gamma rays to view the internal structure of a component. In industry, RT is often used to inspect machinery, such as pressure vessels and valves, to detect flaws.

Radiography works on principle to create density variation (grayscale) on photosensitive material (X-ray film) by exposing them using short-wavelength electromagnetic radiation (Gamma/X-rays).

Such electromagnetic radiation in the form of Gamma/X-ray is capable to penetrate and pass through solid material like metals. This process produces an image of the penetrated object or material on the X-ray film.

Radiography is a well-established technique, which gives a permanent record and is widely used to detect internal flaws in weldments and castings.

A wide range of thickness is covered using a variety of radiation sources like X-ray, Ir-192, Co-60, Se-75, Linear particle accelerators, and Betatron.

Due to its harmful effects of ionizing radiation on living-organism, X-ray/Gamma Source should be handled under strict safety procedures and supervision of qualified personnel.

We at Patels Radiography Services strictly follow safety procedures while working with radiation sources. Also, Patels Radiography Services has safe industrial radiography Enclosures and safety equipment.

Patels Radiography Services provides four types of Radiography.

  • Gamma Radiography
  • Cobalt Radiography
  • External X-ray Radiography
  • Internal X-ray Radiography

Advantages

  • The technique is not limited by material type or density.
  • Any intricate geometry can be inspected.
  • Can inspect assembled components.
  • Minimum surface preparation is required.
  • Sensitive to changes in thickness, corrosion, voids, cracks, and material density changes.
  • Provides a permanent record of the inspection.
