FIELD: defectoscopy.
SUBSTANCE: invention can be used for in-pipe diagnostics of pipeline technical condition. Essence of the invention lies in the fact that the in-pipe technical condition of the technical condition of the pipeline is configured to move inside the pipeline and includes a housing, inside which there are groups of magnetic field sensors, each group of magnetic field sensors includes at least two sensors located on one radial beam having a beginning in the center of the housing, with provision of co-direction of sensor sensitivity axes in the group, as well as a data recording unit connected to the sensors.
EFFECT: improving accuracy and reliability of detection of pipeline defect, evaluation of its location and characteristics, including detection of corrosion zones.
