  • Patent number: 10746538
    Abstract: A compact inspection assembly comprising digital sensors and/or laser measurement systems to validate attributes of pipe and associated threaded connections. An elongate body member is partially inserted into a central bore of a pipe section. A stabilizing centralizer assembly is selectively expanded to engage against the inner surface of the pipe section and prevent axial and rotational movement of the body section relative to the pipe section. An automated sensor assembly, attached to the body member and positioned in proximity to a threaded connection, measures data regarding the pipe and associated threaded connections. The measured and recorded data can be compared to predetermined standards (such as, for example, original equipment manufacturer and/or end user specifications or requirements) to verify pipe/connection compliance with desired standards.

  • Patent number: 10746697
    Abstract: A method of employing an eddy current sensor to perform an inspection of a tube of a steam generator involves accelerating and decelerating the eddy current sensor in a predetermined fashion that substantially reduces the likelihood of damage to the eddy current sensor. The reduction of probe stresses reduces radiological waste and reduces radiation exposure to workers involved in changing damaged probes The recording of an eddy current signal at each of a plurality of equally spaced apart locations along the tube permits the velocity of the eddy current sensor to be varied without compromising the validity of the data that has been recorded. The inspection system employs an encoder that outputs a series of signals as the probe is advanced incremental distances within the tube of the steam generator, and eddy current sensor signals are recorded responsive to at least some of the signals from the encoder.

  • 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: 9890947
    Abstract: Disclosed herein is a method including: performing eddy current testing on a steam generator tube material by using a motorized rotating pancake coil (MRPC) probe, evaluating a test signal measured using the eddy current testing, and predicting the corrosion rate of the steam generator tube material from a noise value in the MRPC inspection signal of the steam generator tube obtained from the evaluating. When the prediction method of a corrosion rate of a steam generator tube according to the present invention is used, the steam generator tube material which has low corrosion rate can be selected at the material selecting step because the corrosion rate can be predicted and the criterions on the corrosion rate of the steam generator tube can be established as the requirements through an eddy current MRPC noise inspection of the steam generator tube material.

  • Patent number: 9512712
    Abstract: Methods including conveying a pipe inspection tool into a wellbore having at least a first pipe positioned within a second pipe, the pipe inspection tool including an electromagnetic sensor. A first excitation signal is transmitted from a first x-coil of the electromagnetic sensor, and a first response signal derived from the first excitation signal is received at the first x-coil or a second x-coil of the electromagnetic sensor. A second excitation signal is then transmitted from a first y-coil of the electromagnetic sensor, and a second response signal derived from the second excitation signal is received at the first y-coil or a second y-coil of the electromagnetic sensor. The first and second response signals are then compared to determine an azimuthal characteristic of the second pipe.

  • Patent number: 9488700
    Abstract: Embodiments relate to Hall effect sensor circuits and devices that provide improved performance, such as reduced residual offset errors and/or improved S/N ratios. In an embodiment, a Hall effect sensor circuit comprises two circuit portions, a first with a higher bandwidth for higher frequencies and having an improved S/N ratio, and a second with a lower bandwidth for lower frequencies and having low residual offset. First and second Hall plates or devices are incorporated in the first and second circuit portions. The first Hall plate can be operated with a larger bias voltage and a larger, high-pass-filtered signal bandwidth, while the second Hall plate can be operated with a smaller bias voltage and a smaller, low-pass-filtered signal bandwidth. Individual output signals from each of the first and second Hall plates can be scaled and combined to provide an overall output signal with the benefits of each circuit portion, including reduced residual offset error and negligible increased noise.
