  • Method for the ultrasonic inspection of pipe and tubing and a transducer assembly for use therewith
    Patent number: 5585565
    Abstract: A transducer assembly and method for the ultrasonic inspection of tubing. An elastic membrane is used to form a reservoir of ultrasonic fluid coupled to ultrasonic transducers with the membrane conforming to the surface of the tubing being inspected. Guide wheels maintain the membrane out-of-contact with the tubing during relative rotational movement of the assembly and tubing during inspection. Water is introduced between the membrane and the tubing to provide ultrasonic coupling of the tubing to the transducers through the fluid of the reservoir.

  • Method and apparatus for characterizing defects in tubular members
    Patent number: 4718277
    Abstract: An ultrasonic inspection device having an array of opposing transducers that longitudinally, transversely, and obliquely transmit sonic beams through tubular members having a range of diameters such that refracted beams meet on the inner surface of the members. Alternate halves of the array of transducers transmit and receive sonic beams reflected from defects in the tubular members using both the pulse-echo and pitch-catch methods.
