DEVICE FOR NON-DESTRUCTIVE TESTING OF STRUCTURES BY GAMMA-RAY FLAW DETECTION Russian patent published in 2019 - IPC G01N23/18 

FIELD: pipelines.

SUBSTANCE: use: for gamma-ray flaw detection of pipelines. Summary of invention consists in the fact that gamma-ray flaw detection system comprises: unit having a hole for ionizing radiation emission outside the unit, supporting the hoop for embracing the analyzed structure, wherein devices are provided for detachable attachment of unit to hoop, comprising several fasteners for attachment of unit in given and different angular positions around hoop, wherein the emitting hole is arranged to direct ionizing radiation to the structure when enveloped by the ring, and the unit is attached to the hoop by one of the fastening elements, wherein fasteners protrude from radially external surface of hoop, and fasteners additionally comprise plate rigidly connected with unit and having cutout for insertion of any of protruding elements therein, as well as element for plate fixation relative to protruding element inserted into cut.

EFFECT: technical result is enabling possibility of strengthening the protection of an operator engaged in non-destructive design control by gamma-ray flaw detection using ionizing radiation, without reducing accuracy of non-destructive testing.
