In order to formalise it's approach to high standards of service MTI has developed a Quality System which is registered compliant with ISO 90011:2015.

Industrial radiography is a long established effective Non Destructive Testing (NDT) method which is a very versatile diagnostic tool.

Radiographic images are formed by passing ionising gamma or X radiation through the piece to be examined on to a radiographic film on the remote side of the test piece. A contrast greyscale image is formed as a result of attenuating factors in the material such as thickness changes caused by internal defects.

Radiation sources commonly used are Iridium 192, Selenium 75 and X-Rays.

Applications

  • Most materials
  • Castings
  • Welded joints
  • Forged components
  • Corrosion Under Insulation (CUI) in piping using profile technique
