Acoustic method for contact-less control of depth of corrosion damage of pipelines relates to non-destructive control of metal articles, in particular to control of depth of corrosion damage of outer wall of the pipe at pone-side access to surface. Main point of the invention is in measurement of time of propagation of ultrasonic vibrations in air. Piezo-transformer of ultrasonic vibrations is placed over article at constant distance from piezo-transformer to axis of pipe with measurement of time of propagation of ultrasonic vibrations from transformer to surface of object of control. By time of propagation of ultrasonic vibrations in air one can mace conclusion on depth of outer corrosion damage of pipe surface. Realization of the method proposed makes it possible to perform continuous automated scanning of metal article and to determine depth of corrosion damage for prediction of its residual resource.
