FIELD: physics, measurement.
SUBSTANCE: invention of flexible stem in assembly of rotary probe is used as carrier of eddy current rotary probe for flaw detection of pipes and is mainly designed for application on rotary probe for flaw detection of pipes (with internal diametre of 13 mm) in steam generators of nuclear power plants of WWER type. Flexible stem in assembly of rotary eddy current probe with high index of flexibility, comprising flexible stem from tearproof wire and wound electroconductive coaxial cables, on top of which flexible sleeve is arranged, besides flexible stem is installed with the possibility of rotation in flexible sleeve, and mentioned coaxial cables are fixed on stem via equal distances by thermosetting tubes.
EFFECT: development of device, which has high flexibility index with the possibility of pushing-pulling and simultaneous rotation.
