  • Patent number: 10324066
    Abstract: A system is disclosed that increases the efficiency of a weld inspector by reducing the amount of weld data that needs to be examined for any non-destructive (“NDT”) phased array and time-of-flight, diffraction ultrasonic testing of welds. The system reads ultrasonic testing data from an NDT scan of a series of metal welds and creates a table of target weld indications ranked by a series of filters representative of predetermined exclusion and significance criteria. The invention acts as a weld analysis concentrator by focusing the attention of an inspector on potential weld flaws that merit their attention, thereby increasing the efficiency of the inspector. The process typically reduces 95% to 98% of the ultrasonic weld testing data that must be reviewed by the inspector, while retaining flaw indications necessary for an inspector's competent review in conformity with various code requirements and regulations.

  • Patent number: 9335296
    Abstract: The systems and methods of the invention pertain to analyzing steam generator tube data for the detection of wear. Further, the invention is capable of performing a comparison of current tube signal data to baseline or historic tube signal data, e.g., from previous and/or the first, in-service inspection of the steam generator. The systems and methods are automated and can generate results to show potential tube-to-tube contact wear areas as well as the progression of tube-to-tube gap reduction within a steam generator tube bundle. In certain embodiments, the invention is capable of comparing current and historical eddy current data to determine the difference that may be related to degradation or other interested phenomena, and of processing and trending historical comparison results to establish normal variance and detect abnormal variances.

  • Patent number: 9279582
    Abstract: A delivery system for remotely driving an eddy current probe through the tubing of a heat exchanger. The system uses a flexible shaft and air pressure to move an inspection probe through the heat exchanger tubes. The flexible shaft initially drives the probe through a sealed conduit to deliver the probe to the tube end at which point a seal on the shaft near the probe head contacts the tube inner surface allowing a buildup of air pressure behind the seal, thus driving the probe through the tube.

  • Patent number: 9228919
    Abstract: Optical methods and systems for the detection of leakages in fluid transporting pipelines. An exemplary system comprises at least one pair of light transmitter and light sensor positioned at the pipe wall itself. The discontinuity of fluid flow by bubbles and entrained particles resulting from a crack on the pipe wall is reflected in the light rays received by the light sensor. The discontinuity is recorded and converted into an optical signal that is transmitted wirelessly to a processing unit at a receiving station.

  • Patent number: 9213018
    Abstract: A method and apparatus for the inspection of electrically conductive components is described. The described apparatus comprises a sensor module having a magnetizer unit suitable for generating a variable DC magnetic field within the test component and an eddy current probe. The variable DC magnetic field and eddy current probe are configured to perform a partial saturation eddy current test upon the test component. The eddy current probe further comprises a magnetic field sensor that provides a means for measuring the permeability within the test component. Employing the magnetic field sensor provides apparatus that is more accurate and flexible in its modes of operation since such sensors provide a means for the actual permeability of a material being tested to be measured. The described methods and apparatus find particular application in the inspection of tubular components used in the oil and gas exploration and production industries.

  • Patent number: 9207211
    Abstract: An object is to improve the precision of estimating a blockage ratio or a deposited-scale thickness. In a deposit measurement apparatus that estimates a blockage ratio of a gap between a wall surface of a through-hole and an outer surface of a heat-conducting pipe or the thickness of a deposit deposited at the gap, an eddy-current flaw detection probe (61) acquires an eddy-current flaw detection signal by scanning inside the heat-conducting pipe with a sensor; and a processing device (62) estimates the blockage ratio at the gap or the thickness of the deposit deposited at the gap by using the eddy-current flaw detection signal for the gap of the pipe-supporting-plate protrusion in the through-hole.
