Method of compressing data in an ultrasonic pipe inspection probe

In a method of compressing data obtained from ultrasonic propagation-time measurements made at a given pulse-repetition rate over a broad surface by an inspection probe which slides through the pipe in order to detect corrosion and other abnormalities in the pipe, the particular physical characteris...

Zusammenfassung:In a method of compressing data obtained from ultrasonic propagation-time measurements made at a given pulse-repetition rate over a broad surface by an inspection probe which slides through the pipe in order to detect corrosion and other abnormalities in the pipe, the particular physical characteristics of the pipe are taken into consideration whereby a high data-compression factor and, for the subsequent analysis, reliable reproduction of the actual conditions in the pipe are achieved.
