Patent ID: 8375795

Claim:
A method for non-destructive ultrasound inspection of a high-pressure line as a testing piece by means of a pulse-echo method, wherein the high-pressure line is conveyed to a near-field range of at least one ultrasonic transducer and an ultrasonic pulse is emitted with a perpendicular sound incidence on the high-pressure line in such a way that the high-pressure line is completely captured in its cross section by the near-field sound emission caused by the ultrasonic transducer, and reflected ultrasonic pulse(s) is/are received by the ultrasonic transducer and/or, optionally, further ultrasonic transducers, the associated echo delay times are recorded and, optionally, evaluated, wherein, during an evaluation, an echo delay time range until an echo or multiple echo at an external wall of the high-pressure line facing away from the ultrasonic transducer, preferably between an echo on an internal wall closest to the ultrasonic transducer and a third echo on the external wall facing away from the ultrasonic transducer, is subjected to an amplitude evaluation.
