System and method for characterizing material condition. The system includes a sensor, impedance instrument and processing unit to collect measurements and assess material properties. A model of the system may be used to enable accurate measurements of multiple material properties. A cylindrical model for an electromagnetic field sensor is disclosed for modeling substantially cylindrically symmetric material systems. Sensor designs and data processing approaches are provided to focus the sensitivity of the sensor to localize material conditions. Improved calibration methods are shown. Sizing algorithms are provided to estimate the size of defects such as cracks and corrosion. Corrective measures are provided where the actual material configuration differs from the data processing assumptions. Methods are provided for use of the system to characterize material condition, and detailed illustration is given for corrosion, stress, weld, heat treat, and mechanical damage assessment.

A defect inspection system includes a storage. The defect inspection system also includes a corrosion enhancing defect manager that obtains a circuit card including a trace that is to be encapsulated by a protective layer adapted to reduce corrosion of the trace; applies a voltage potential to the trace while the circuit card is disposed in a visual indicator bath; obtains an image of the trace while the voltage potential is applied; makes a determination, based on the image, that a visual indicator generated by the visual indicator bath is included in the image; and based on the determination: identifies a portion of the trace corresponding to the visual indicator; and applies encapsulant to the portion of the trace.

A crack detection device includes: a sensor unit that has a three-layer structure of conductor-insulator-conductor and is attached to a structure; a frequency characteristics acquisition unit that sweeps a predetermined frequency range to acquire a plurality of frequencies at which the impedance of the sensor unit is maximum or minimum; a crack presence/absence determination unit that determines the presence or absence of a crack based on a nonuniformity of the plurality of frequencies; a crack position table in which a relationship between crack positions and frequency shift directions is recorded; and a crack position detection unit that, when the crack presence/absence determination unit determines that there is a crack, takes a difference between two frequencies acquired by the frequency characteristics acquisition unit to determine a sign, and then refers to the crack position table in accordance with the sign to detect a crack position.

A system for reduced noise during remote field testing (RFT). The system, while moving an RFT probe through a structure: generates, RFT probe, a magnetic field. The system detects, at a detector solenoid on the RFT probe, a measured magnetic field which is the magnetic field modified by the presence of nearby pipe, and wherein the detector solenoid has a non-uniform solenoid response (i.e. a non-uniform turn density and/or cross sectional winding area) along a longitudinal axis extending from a one end of the detector solenoid to the opposite end of the detector solenoid. The system then identifies and measures pipe properties from an analysis of the measured magnetic field, via signal processing in conjunction with modeling.

Systems and methods include a computer-implemented method for inspection. Removable sensors are installed on equipment used in hydrocarbon facilities at locations susceptible to high temperature hydrogen attack (HTHA). Attachment uses adaptable hybrid pads. Surface data captured using the sensors includes surface temperatures, per hydrogen (Ph) measurements, and methane measurements for methane escaping from external surfaces of the equipment. A presence of cracks in the equipment base metal is determined. An HTHA susceptibility analysis of the equipment is performed based on the presence of the cracks and by analyzing the surface data and mapping potential HTHA cracks and early signs of methane formation. The steps are repeated on other locations. An inspection result and assessment, generated using the captured surface data, includes a final analysis of assessment reports indicating a likelihood of cracks propagation and a presence of fissuring inside the equipment base metal.

A method of detecting defects or deterioration in the sidewalls of can bodies during production of the can bodies within a can bodymaker. Each can body is formed by pushing a cup, mounted on a punch of a reciprocating ram, through one or more dies contained within a tool pack of the bodymaker. The method comprises: obtaining output signals from one or more eddy current sensors arranged around the ram axis outside of the tool pack and adjacent to an exit end of the tool pack; processing the output signals to detect passage of open ends of can body sidewalls past the sensor(s) and thereby determine measures of the heights or thicknesses of can body sidewalls; and analysing the determined measures to identify can body sidewall defects or deterioration.

Systems, methods and apparatuses for inspecting a tank containing a flammable fluid are provided. The system includes a vehicle having a propeller, a latch mechanism, a pressure switch, and an inspection device. The system includes a control unit in communication with the propeller, the latch mechanism, and the inspection device, and electrically connected to the pressure switch. The control unit powers on responsive to the pressure switch detecting an ambient pressure greater than a minimum threshold. The control unit receives, from the latch mechanism, an indication of a state of the latch mechanism. The control unit determines that the cable used to lower the vehicle into the tank containing the flammable fluid is detached from the vehicle. The control unit commands the propeller to move the vehicle through the flammable fluid. The control unit determines a quality metric of a portion of the tank.

A method of inspecting a material includes examining a surface of a test material with an eddy current sensor and applying an X-ray fluorescence analysis to the surface of the test material at the same location at which the eddy current examination was performed.
