FIELD: measurement technology; diagnosis of tube walls. SUBSTANCE: proposed method consists in location of flaws by ultrasonic technique, magnetic fluxes, matching and completing results of examinations in the course of analysis of obtained data; according to invention, pipe line walls are additional subjected to magneto-optical examination; results of this examination are matched with ultrasonic examination and magnetic flux examination. EFFECT: enhanced reliability of inter-tube diagnosis due to enhanced accuracy of estimation of length of crank; possibility of analyzing thread-like and multichannel corrosion and long-seam fatigue cracking and pitting.
