RADIO-GRAPHIC NON DESTRUCTIVE TECHNIQUE

Gamma Ray Inspection: Industrial Radiography

Radiographic Testing

Radiography Testing (RT)

General Principles of Radiography

The part is placed between the radiation source and a piece of film.  The part will stop some of the radiation.  Thicker and more dense area will stop more of the radiation.

• The energy of the radiation affects its penetrating power. Higher energy radiation can penetrate thicker and more dense materials.

• The radiation energy and/or exposure time must be controlled to properly image the region of interest.

• The film darkness (density) will vary with the amount of radiation reaching the film through the test object.

Radiography Interpretation of Weld Discontinuities:

Advantages:

• Technique is not limited by material type or density.
• Can inspect assembled components.
• Minimum surface preparation required.
• Sensitive to changes in thickness, corrosion, voids, cracks, and material density changes.
• Detects both surface and subsurface defects.
• Provides a permanent record of the inspection.

Gamma Ray Inspection

Here at Global X-Ray & Testing Corporation, we specialize in Gamma Ray Inspection for external evaluation of structural / process piping and pipeline construction. High quality gamma ray inspection equipment and experienced personnel result in first rate performance on each industrial radiography project we undertake.
