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.
Claims29
A method for ultrasonic inspection of tubulars, said method comprising:
- providing a first circular array of composite transducers, said transducers having a proximate curved surface;
- passing a tubular past said first array, said tubular having an outer peripheral surface, wherein said outer peripheral surface has a radii of curvature, and said proximate curved surface has a radii of curvature greater than the radii of curvature of the outer peripheral surface;
- and
- inspecting for abnormalities in the tubular utilizing said transducers.
