FIELD: non-destructing inspection of pipelines.
SUBSTANCE: intratube flaw detector's transducer system set has row of transducers' holders mounted concentrically along perimeter of case of flaw meter. Any holder is disposed in parallel to longitudinal axis of case of flaw detector. At least one transducer is mounted onto holder. Any holder has its front end connected by hinges to lever to follow movement of flaw detector. Other end of lever is fastened by hinges onto case of flaw detector. One end of spring, working for compression in its working position, is fastened to holder at some distance from point of fastening of lever. Other end of spring is fastened to case. Permanent contact with wall of pipe is provided as at straight parts and at rounded parts and in sites where diameter of pipe changes to keep lateral stability during movement of system.
EFFECT: higher lateral stability.
