    Abstract: A nondestructive inspection apparatus includes a pair of guided wave sensors disposed on an outer surface of a piping and a guided wave inspection device connected to the pair of guided wave sensors which, outputs a transmitting signal for propagating a guided wave to the guided wave sensors, and obtains a receiving signal by receiving a propagated signal by the guided wave sensors. An inspection-result storage device stores the guided wave as a digitized signal of the received wave and an inspection-result diagnostic device performs arithmetic processing of judging whether or not a signal associated with a defect exists.

  • Patent number: 8783111
    Abstract: Provided are an ultrasonic testing probe and an ultrasonic testing apparatus capable of reducing the time required for flaw detection while maintaining the flaw-detection capability, irrespective of the shape of the inner surface of a tested object. A first probe (21) and a second probe (22) are provided, in each of which a plurality of oscillators that transmit ultrasonic waves to a tested object (T) and detect the ultrasonic waves reflected from the tested object (T) are arrayed. The first probe (21) is disposed closer to a flaw in the tested object (T) than the second probe (22) is. The first probe (21) generates longitudinal ultrasonic waves that propagate on an inner surface (T5) of the tested object (T) opposite to an outer surface (T2) thereof where the first probe (21) and the second probe (22) are disposed and transverse ultrasonic waves that propagate from the outer surface (T2) toward an inside of the tested object (T).

  • Patent number: 8776604
    Abstract: An ultrasonic probe for detecting a flaw by ultrasonic waves in a tubular test object includes a plurality of transducers arranged along an annular curved surface, wherein the annular curved surface is obtained by cutting a predetermined spheroid with two parallel planes facing to each other that do not pass through a center of the spheroid and do not sandwich the center of the spheroid, said two parallel planes being orthogonal to a rotational axis of the spheroid. A shape of said annular curved surface is determined so that when transducers appropriately selected from said plurality of transducers are caused to transmit and receive ultrasonic waves, respective internal refraction angles ?? of the ultrasonic waves are approximately equivalent regardless of propagation directions of the ultrasonic waves.

  • Patent number: 8746070
    Abstract: A method and apparatus for phased array ultrasound testing of piping that complies with present-day codes but allows more thorough flaw detection capability. A tapered wedge with a concave face is calibrated by submerging the wedge under sonic coupling fluid, thereby allowing sonic coupling of the concave wedge face to a flat reference plate with minimal error. The flaw detector is configured to display A-scan and S-scan data concurrently and to sweep between 30-70 degrees. A-scan data corresponding with conventional preferred inspection incidence angle is selected, and reject levels are set to 0% to meet current inspection standards. S-scan data allows for detection of flaws that might otherwise be undetectable using only A-scan data. A palette adjustment feature remaps the colors assigned to lower intensity return values so that they are not displayed on the S-scan, thereby de-cluttering sectorial data without filtering A-scan data.

    Abstract: An ultrasonic sensor assembly for a test pipe includes a sensor array. The sensor array includes a plurality of sensor elements for detecting a characteristic of the test pipe and included a flexible backing material on which the plurality of sensor elements are supported. The sensor array is adjustable in length to form an adjusted length. An excess portion is removed from the sensor array to form the adjusted length. This adjusted length of the sensor array substantially matches a perimeter distance around an outer surface of the test pipe. An associated method of positioning the ultrasonic sensor assembly on the test pipe is also provided.

  • Patent number: 8627724
    Abstract: A non-intrusive sensor for in-situ measurement of recession rate of heat shield ablatives. An ultrasonic wave source is carried in the housing. A microphone is also carried in the housing, for collecting the reflected ultrasonic waves from an interface surface of the ablative material. A time phasing control circuit is also included for time-phasing the ultrasonic wave source so that the waves reflected from the interface surface of the ablative material focus on the microphone, to maximize the acoustic pressure detected by the microphone and to mitigate acoustic velocity variation effects through the material through a de-coupling process that involves a software algorithm. A software circuit for computing the location off of which the ultrasonic waves scattered to focus back at the microphone is also included, so that the recession rate of the heat shield ablative may be monitored in real-time through the scan-focus approach.
