Abstract: In a nondestructive inspection of a defect of a welded portion of a pipe or a pipe member, work efficiency of a radiation transmission test is improved by reducing a burden on a worker, and an inspection accuracy is improved. Imaging data is acquired by transmitting radiation through a welded portion of the pipe to be inspected. Processing of associating determination data indicating a result of determining a defect of the welded portion of the pipe to be inspected based on a distribution of a transmission intensity of the radiation obtained from the imaging data with image data showing the distribution of the transmission intensity of the radiation is performed. As a result, through use of the imaging data, image data and determination data associated with the image data can be obtained, and the burden on the worker can be reduced.

Abstract: The apparatus is useful for monitoring integrity of casings, tubings, and other tubular strings in oil and gas wells. An apparatus for defectoscopy of downhole casings includes several units in a housing. An electromagnetic field generation unit generates excitation pulse of a specified amplitude and duration. It includes an exciter coil containing a core made a high magnetic permeability material. A pick-up sensor unit includes an integral pick-up coil and radial pick-up coils mounted around the exciter coil winding. Each pick-up coil has a U-shaped core with poles directed perpendicularly to the surveyed pipe surface and having a center line parallel to the center line of the exciter coil winding. A data control, acquisition, and processing unit includes operational amplifiers with variable amplification factors and analog-to-digital converters (ADCs) that transmit signals from the pick-up coils to software for casing defect analysis.

Abstract: An accelerated corrosion test apparatus includes: a moisture sensor disposed near the reinforcing steel exposed from a cracked portion of concrete; a weight measuring instrument that measures a weight of the reinforced concrete specimen; and a control terminal that is connected both to the moisture sensor and to the weight measuring instrument and controls a temperature and humidity control device, thereby alternately and repeatedly performing a wetting step of supplying moisture to the inside of a crack in the cracked concrete, and a drying step of removing moisture in the inside of the crack and moisture on the exposed surface of the reinforcing steel, wherein the control terminal terminates the wetting step and starts the drying step when moisture is detected in the moisture sensor, or when change in slope of weight change of the reinforced concrete specimen is detected, after the start of the wetting step.

Abstract: The present invention provides a highspeed advanced system to identify and classify the area of anomalies in a railroad rail. This is achieved by using a novel linear array solution that employs parallel transmission of an ultrasonic beam and the use of a virtual synthetic aperture to receive reflected echoes. This integrated system has the capability to locate and classify near surface horizontal defects at speeds more than 40 km/h and at the same time maintaining a constant pulse density of at least 4 mm or less per incremental longitudinal movement.

Abstract: The present invention provides a way to increase the density of Hall effect sensors on a MFL inline inspection tool mounting the sensors on a first circuit board which overlies a second circuit board. Op amps for the sensors which condition and filter the analog signal from the sensors are mounted on the first circuit board. Microprocessors mounted on the second circuit board receive the analog signal from the op amp and translate it into a digital signal. Use of the stacked circuit boards doubles the amount of area to mount the sensors and their op amps and microprocessors while maintaining the same footprint. This results in being able to increase the number of Hall effect sensors in that footprint area. In other embodiments the number of layers of circuit boards may be increased beyond two.

Abstract: The present technology relates to a method of inspecting a welding defect. The method includes: manufacturing an electrode assembly sample by welding an electrode lead on an electrode tab formed on an electrode assembly; measuring a tensile strength, a torsional strength and a peeling strength of a welded portion between the electrode tab and the electrode lead for the electrode assembly sample; deriving correlation between whether there is a welding defect and each of the tensile strength, the torsional strength, and the peeling strength; and deriving a reference value for determining whether there is a welding defect for the tensile strength, the torsional strength, and the peeling strength, respectively.
