  • Method of in-tube ultrasonic flaw detection
    Patent number: 6651503
    Abstract: The claimed method of in-tube ultrasonic flaw detection of pipelines is effected, in accordance with one embodiment, by placing inside a pipeline an inspection pig or flaw detector having ultrasonic transducers, devices for measurements, processing and storage of the measured data. During the pig travel, the transducers emit probing ultrasonic pulses and receive the reflected pulses corresponding to said probing pulse thus deriving data on the time intervals corresponding to the transit time of said pulses, the measured data being converted and stored.
    Type: Grant
    Filed: May 13, 2002
