FIELD: physics. ^ SUBSTANCE: in the presence of ultrasonic contact with pipe the echo-pulse signals reflected from flaws are accepted by transformers located along the pipe, converse to codes which are selected on temporary parameters, parameter of amplitude (phase), and are logically summarised and compared to rejection measure, thus in the course of the control simultaneously traversal and dilatational ultrasonic oscillations and eddy current (magnetic) oscillations are radiated. ^ EFFECT: increase of informativeness and reliability of results of pipes control. ^ 8 cl, 11 dwg |
