X-Ray Radiometric Inspection of Welds at Building Gas Main Pipelines

S. B. Krasilnikov, G. I. Sonin

The principle of radiometric set of equipment operation is discussed. Results of this set of equipment field testing and testing in laboratory conditions with the use of high stabilized apparatus RPD – 200 P for inspection of welds of pipeline tubes with diameter 1420 mm and are given. Contrast sensitivity of the equipment and its wide signal dynamic range with following digital processing of images make it possible to provide detectability, that is highly competitive with the results, got with the use of radiography and radioscopy in similar conditions.
