FIELD: measuring equipment.
SUBSTANCE: invention can be used: for evaluation of geometrical sizes of a pipe section wall and weld seams defects. Core of the invention is that according to an ultrasonic intra-pipe defectoscope data with the help of related indications search evaluated are the length, the width and the depth of a defect.
EFFECT: provided is the possibility of evaluation of geometrical parameters, classification of type of a defect in a pipe section wall and weld seams at reduction of labour costs for processing a separate section of an oil pipeline and at reduced time for detecting hazardous defects.
