(PRACTICAL ASPECTS OF USING THE MOBILE DIGITAL RADIOGRAPHY SYSTEMS)
Modern trends explain the need for new methods of diagnostics of the main gas pipelines welded joints. Analogue methods of inspection using the radiographic film are gradually being replaced by the digital and automated systems. Automation of non-destructive testing makes it possible to reduce the cost of consumables, facilitate the work of specialists, as well as increase the level of industrial safety.
The article describes the practical aspects of using the mobile digital radiography systems at the facilities of Gazprom transgaz Kazan LLC. The advantages of using such complexes are revealed. Minor disadvantages that may arise during radiographic inspection of pipes over 1000 mm in diameter and one of the ways to eliminate them are shown. The experience in using various X-ray devices and options of attaching them to the complexes are described. It is established that the quality of the pictures obtained on the detector exceeds the quality of the pictures obtained on the phosphor imaging plates and radiographic film.
During the work with digital radiography complexes different X-ray devices were tested, and the degree of influence of the choice of ionizing radiation source on the quality of the images and production safety was analyzed. X-ray pictures obtained during control measures on digital detectors were presented, including the use of special filters, which allow better considering and analyzing defects of welded joints.
In the conclusion, the main advantages of using digital radiography systems are formulated.
