From 1993 till nowadays our specialists develop, produce and provide Russian gas industry with NDT equipment for main pipeline testing. From 1996 our multi channel eddy current flaw detector is used for measuring of stress-corrosion cracks to provide a recommendation on pipeline safety. Now 16 channel version of it with magnetic carriage of probe is prepared to release. Significant contribution into main pipeline inspection and detection of stress-corrosion flaws was provided by our other eddy current flaw detectors: the first one - with indication of crack danger, another one - with indication of crack danger and with infinite reliability of flaw detector probe. From 1996 more than 10 thousand kilometers of pipeline have been inspected, and with that data an algorithm of pipe condition evaluation has been developed for pipelines with flaws in case of troubles with its repair. In contrast to magnetic methods, that equipment doesn't make mistakes because of magnetic or metal structure influencing on tests. It successfully detects flaws through coating of pipelines. With significantly increasing of volume of repairing that technique will finally fight entire gas industry. Stresses and deformations are playing main role in stress-corrosion formation. So the additional apply of our magnetic structure scope for pipeline inspection within pipe testing up to destruction allows us to investigate the metal stress state simultaneously with sizing of stress-corrosion cracks.
