How to improve the inspection of pipes using infrared thermography

Melika Losic, Bosnia and Herzegovina 16-18

In the industrial practice of the piping inspection, a temperature gradient higher than 2 K on the outer surface produced by a defect on the inner wall of the pipe is accepted as the limit of detection. Our intention is to prove that for a well-defined temperature range, a typical infrared camera for industrial use has sufficient sensitivity and contrast to reliably detect defects that produce a significantly lower temperature gradient on the outer surface, down to 0.4 K. This will be verified by pipe samples with artificially produced defects on the inner wall of the pipe. The obtained results will be analyzed, discussed, and applied in real industrial conditions. The application restrictions and limitations will be considered and discussed.
