FIELD: pipelines.
SUBSTANCE: group of inventions relates to the nondestructive inspection of pipelines. Method for the magnetic monitoring method further comprises steps of moving the diagnostic robot in steps, where the length of each pitch is equal to the width of the variable magnetic field sensor capture, at that, during rotation of the rotation assembly, the amplitude of the variable magnetic field is fixed for at least two different frequencies in each point of the monitored surface with the possibility of estimating the depth of the defect and determining its position by associating signal amplitudes to the longitudinal and angular coordinates.
EFFECT: technical result is higher accuracy of detecting defects of pipelines.
