Abstract
The invention relates to a method for the non-destructive ultrasound inspection of a high-pressure line as a testing piece by means of the pulse-echo method, where 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 the 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.
