A device to inspect a pipeline includes a device housing movable relative to the pipeline, a radiation device, and an imaging device. The radiation device is coupled to the device housing and disposed adjacent to the pipeline. The imaging device is coupled to the device housing and disposed adjacent to the pipeline. The imaging device is disposed opposite to the radiation device relative to the pipeline. The imaging device receives radiation from the radiation device to provide an imaging signal. Because the radiation device and the imaging device are disposed opposite to each other relative to the pipeline, the pipeline inspection device can provide an enhanced image in a single pass of the pipeline.

A method and apparatus for testing a fuse between two plastic pipes without destroying the fuse is performed in the field. The method and apparatus include a source of X-ray radiation and a scanning plate that has pixels that change state when exposed to this radiation. The source of the X-ray radiation is positioned on one side of the fuse and the scanning plate is positioned on another side so that the x-ray radiation passes through the fuse. The x-ray image from the scanning plate makes visible internal voids, weak fuses, and evidence of movement after the plastic of the fitting/pipes melted and flowed together. With such, the quality of the fitting is evident without cutting or otherwise destroying the fitting and, therefore, only weak or otherwise compromised fittings need be cut and redone.

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.

A frame assembly for inspection of pipeline girth weld, having a support frame releasably coupled to a mounting band that comprises of two clamshell halves. The clamshell halves are coupled via quick release coupling mechanisms. By removing one of the clamshells, or uncouple the two clamshells at one coupling point, the frame assembly permits a RTR scanner assembly to be laterally displaced along the length of the pipeline.

Some embodiments include a radiographic inspection system, comprising: a drive mechanism configured to move along a structure; a detector attached to the drive mechanism; a radiation source attached to the drive mechanism and positionable relative to the detector such that a width of the structure casts a radiation shadow on an active area of the detector; and control logic coupled to the detector and configured to: receive an image from the detector; generate side wall loss information based on the image; and generate bottom wall loss information based on the image.

A correction apparatus includes an acquisition unit that acquires first image data representing a radiographic image generated by the radiation detector which is irradiated with the radiation in a state of being provided on a portion of an object to be inspected different from a portion to be inspected so as to be bent along an outer shape of the object to be inspected, and a correction unit that generates correction data on the basis of the first image data and corrects second image data representing the radiographic image generated by the radiation detector which is irradiated with the radiation in a state of being provided on the portion to be inspected so as to be bent along the outer shape of the object to be inspected.

Systems and methods for robotic inspection of above-ground pipelines are disclosed. Embodiments may include a robotic crawler having a plurality of motors that are individually controllable for improved positioning on the pipeline to facilitate image acquisition. Embodiments may also include mounting systems to house and carry imaging equipment configured to capture image data simultaneously from a plurality of angles. Such mounting systems may be adjustable to account for different sizes of pipes (e.g., 2-40+ inches), and may be configured to account for traversing various pipe support structures. Still further, mounting systems may include quick-release members to allow for removal and re-mounting of imaging equipment when traversing support structures. In other aspects, embodiments may be directed toward control systems for the robotic crawler which assist in the navigation and image capture capabilities of the crawler.

Disclosed is a measurement probe for measurement of elements in a mineral slurry. The probe includes a housing having an X-ray window. The housing encloses: an X-ray source positioned to emit source X-rays at the X-ray window; an X-ray detector positioned to detect X-rays from the X-ray window; and a control module. The control module is configured to: control operation of the X-ray source and the X-ray detector; process X-rays detected by the X-ray detector to generate X-ray spectra data; and process the X-ray spectra data to determine the quantity of one or more elements of interest in the mineral slurry. The measurement probe includes a probe mount adapted to couple the measurement probe to a pipe mount on a pipe carrying the mineral slurry; when the probe mount is coupled to the pipe mount, the X-ray window provides a transmission window for X-rays into a lumen of the pipe.

The present invention relates to a method to determine geometrical parameters of an object under study by radiography, the object can be described geometrically, wherein intercepts that go through the material of the object under study can be determined from a projection of the object—e.g. a tube—imaged by an X- or gamma-radiation source if exposition data of the radiographic image are available. These intercepts that go through the material of the object—i.e. the intercept curves—allow that the object under study—e.g. the tube—have a dimension that is larger than the dimension of the device (film/detector) used to take the radiographic image. During the course of said method, the source of radiation, the object under study and the device (film/detector) used to take the radiographic image are in a fixed position.
