METHOD FOR TURNING THE IN-TUBE FLAW DETECTOR IN THE TRAY AND THE DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2022 - IPC G12B3/02 F16L101/30 

FIELD: pipeline equipment.

SUBSTANCE: invention is aimed at turning the flaw detector along its longitudinal axis during maintenance work, preparation for start-up and inspection after passing through the pipeline. The essence of the invention lies in the fact that due to the use of a device for fixing the hinge joints of the flaw detector sections containing two stops made in the form of a plate with protruding elements and a hole with the possibility of fixing on both sides on the fork of the hinge joint of the flaw detector section with a bolt-nut connection, and two clamps made in the form of pads with support elements and ridges with two holes with the possibility of fixing from above and from below on the fork of the hinge joint of the flaw detector section with a bolt-nut connection, the flaw detector is rotated in the tray by lifting means, excluding damage to the structural elements of the flaw detector and the tray.

EFFECT: ensuring the possibility of turning the flaw detector, as well as simplifying the process of maintenance and inspection of the flaw detector by eliminating the mobility of the hinge joints of its sections.
