  • Ultrasonic tubulars inspection device
    Patent number: 7293461
    Abstract: A system, method, and apparatus for ultrasonic detection of flaws or defects in oil field tubulars utilizing composite transducers. An array of composite transducers are utilized to detect anomalies in the tubulars, such as transverse, wall or longitudinal defects. The use of the composite transducers allow for a greater inspection area over traditional transducers thereby reducing the number of channels needed for inspection of the tubulars.
