  • Patent number: 11085899
    Abstract: The invention provides a method and apparatus for assessing a condition of a fluid conduit from its interior. The method comprises providing a measurement apparatus comprising at least one wideband acoustic transducer within the fluid conduit and transmitting a wideband acoustic signal from the measurement apparatus to excite a broadside resonance in at least a portion of the fluid conduit. A wideband acoustic signal is received in the measurement apparatus due to a broadside resonant response of the fluid conduit to obtain a wideband acoustic data set; and the data set is analysed to assess the condition of the fluid conduit.

  • Patent number: 10704901
    Abstract: Systems, methods and computer storage mediums accurately measure wall thickness in a region of interest included in complex curved structures. Embodiments of the present disclosure relate to generating a wall thickness loss distribution map of a region of interest that provides an accurate representation of wall thickness for the region of interest included in a complex curved structure. The wall thickness loss distribution map is generated from a two-dimensional model of the wall thickness loss distribution of the region of interest. The two-dimensional model is converted from a three-dimensional representation of the wall thickness loss distribution of the region of interest. The three-dimensional representation of the wall thickness is generated by ultrasonic waves generated by a transducer system that propagated through the region of interest.

  • Patent number: 8601875
    Abstract: The invention locates impaired sections of a pipeline, such as sections where the wall of the pipeline has been weakened or thinned. It provides a moveable device which passes through the pipeline and which has a first station. The moveable device has means to locate its position accurately. There is a second station, which is mounted either on the moveable device or in association with a fixed location on the pipeline wall. Either the first station or the second station has an acoustic or seismic pulse generator, and the other has a pulse receiver. The time taken for a pulse to travel from the pulse generator to the receiver is found to vary with the condition of the pipeline wall at the location where the moveable device is located at the time it receives (or sends) the pulse. The rate of change of velocity of the pulse as the device passes different locations in the pipeline is also found to vary with the condition of the pipeline wall at such location.

  • Patent number: 8479577
    Abstract: Apparatus and methods are provided for non-destructive in-line pipeline inspection utilizing electromagnetic acoustic transducer (EMAT) technology wherein the EMATs are arrayed circumferentially in a belt around the body of the tool and wherein the EMAT belt includes a plurality of EMAT clusters, each cluster including a transmitting EMAT essentially sandwiched between a pair of receiving EMATs. The EMAT arrangement enables a single receiving EMAT to monitor both the test signal and the returning reflection from the pipewall defect thus providing each signal with its own internal reference. The number of transducers and their positional relationship limits the generation of interference signals, is conservative in power consumption, and provides a tool having enhanced negotiability through the pipeline.

  • Patent number: 8408062
    Abstract: A scanning device (36) is useful for scanning a body, especially a stud (10), from a bore (13) which extends through the body or stud (10) and is accessible from the outside. The scanning device (36) includes a probe (15) which is fastened on a cylindrical rod (14) and can be inserted into the bore (13) for scanning the body or stud (10), which probe, by displacing the rod (14) in its longitudinal direction is longitudinally displaceable in the bore (13), and by rotating the rod (14) around its cylinder axis (34) is rotatable around the bore axis. A compact and light construction, and flexible applicability, are achieved by a compact, controllable drive unit (20), through which the rod (14) extends and which longitudinally displaces and/or rotates the rod (14) depending upon selection, for displacing and rotating the rod (14).

  • Patent number: 8397575
    Abstract: Ultrasonic transducers and methods for detecting oblique flaws in cylindrically-shaped objects using pulse-echo testing are provided. By mounting one or more transducers on a rotary tester for testing manufactured objects such as tubes and bars, offsetting each transducer horizontally from its position if it were to emit a beam that is perpendicular to the object's outer surface, and actuating the transducer so as to emit an angled beam, oblique surface flaws and internal flaws may be reliably detected without reducing inspection speed, significantly adding to transducer cross-talk, or requiring significant additional hardware or processing.

  • Patent number: 8373411
    Abstract: In an in-line pipe inspection tool, sensors for inspecting the pipe are mounted on sensor blocks moveable relative to the body of the tool. However, when the sensor blocks move radially to conform to different pipe diameters, the circumferential distances between the sensors changes. To ameliorate the effect of this, the sensor blocks have a shape such that one axial edge of each sensor block circumferentially overlaps the opposite edge of an adjacent sensor block. With such an arrangement, when the sensor block are operating at minimum diameter, part of one sensor block will overlap an adjacent block, in the circumferential direction. As the diameter of the pipeline in which the pig is used increases, the degree of overlap will reduce, and may even reduce to zero, but there will still be no overall axial gaps between the sensor blocks. Thus, by suitable shaping of the sensor blocks the tool can be used with a wide range of pipe diameters.

  • Patent number: 8356518
    Abstract: An apparatus for inspecting a pipe comprising a body adapted for passage through the bore of a pipe to be inspected, a main transducer array comprising a plurality of circumferentially spaced transducers for transmitting ultrasound energy, the transducers being mounted on the body for movement between a retracted position, wherein the body can freely move through the bore of the pipe, and an extended position wherein the plurality of transducers are pressed into operative contact with the inner wall of the pipe. An actuator selectively urges the plurality of transducers to their extended positions. A control transmits ultrasound energy into the pipe to propagate a guided wave within the pipe walls in at least one longitudinal direction along the pipe when the transducers are in their operative position and receives the propagated wave and analyzes the wave to determine the presence or absence of defects in the pipe wall.
