  • a device for automated, digital, radiographic inspection of pipelines is known (Patent US7656997, published September 15, 2008, IPC: G01N 23/02).

  • the positioning and moving device After completing a complete revolution of the positioning device and moving around the pipeline, the positioning and moving device performs a longitudinal movement, designed for non-contact, non-destructive testing of pipelines. The above steps are repeated many times until the completion of the pipeline study.
  • the system with wired data transmission provides reliable control and data transmission.
  • the disadvantages of the wired system are: additional time spent on preparing the system for operation (unwinding, connecting and reverse disconnecting and rewinding wires); additional weight and dimensions of the complete system; restriction on the distance between the place of work of the x-ray source and the location of the operator.
  • the length of the wires does not exceed 50 meters.
  • sources with high radiation energies and high power such a distance may not be sufficient for the required protection of the operator from radiation; inconvenience of working with wires in some cases (for example, winding wires around a pipe when scanning with an annular weld detector).
  • Each of the above devices contains a positioning device, a digital X-ray detector, an X-ray source, a standalone power supply, a data acquisition, processing, storage and visualization system that includes a detector, a battery, a transmitter, a receiver (e.g., an operator computer) connected by wireless communication (http://vidisco.com/ndt solutions / ndt systems).
  • the specified system is usually manually installed in the shooting location, the system operator waits for the radiation signal to appear, after it appears or is removed image by applying a signal to the detector via a wired remote control, or a single image is taken on the command of an operator transmitted wirelessly.
  • the disadvantage of systems with wireless communication is:
  • a communication failure leads to the need to stop the entire shooting process, and to continue the process only after the connection is restored.
  • the radiation duration is set at the source in advance and after a certain time the radiation automatically turns off.
  • Wireless communication to control the radiation source is usually not.
  • a possible shooting delay caused by the failure of the wireless connection makes it necessary to set the operating time of the radiation source with a margin or to repeat the shooting, including the radiation source again. This leads to an increase in the time taken to control the product, shortens the life of the radiation source and detector and increases the likelihood of harmful effects of radiation on the device operator.

  • Detectors 2 are programmed by the operator to start work and receive an image at the moment the radiation from the source reaches the desired power level.
  • X-ray source 5 is also programmed to work for a certain time, the minimum necessary for shooting. The operator, after starting the radiation source 5, until the radiation is turned on, is removed to a safe distance from the control point of the pipeline, i.e. the place of work of the radiation source 5.
  • the proposed system allows the use of a mechanical device that moves the detector along the object by the size of the frame.
  • the position of the x-ray source 5 can either change or remain unchanged for shooting several frames along a rectilinear object.
  • the position of the radiation source 5 may remain unchanged for all frames.
  • detector 2 At each stop, detector 2 generates one image. These images are stored in the processor 3. In this case, if the wireless connection between the processor 3 and the operator receiver 4 is interrupted or interrupted, the frame-by-frame process does not stop, and the images are not lost.

  • the system for obtaining images of welds is carried out as in the first embodiment. However, the images are stored in the memory of each processor 3 of detector 2. Next, data from each processor 3 is transmitted by the transmitter wirelessly to the receiver 4 of the operator.
  • the claimed system of radiographic control of welded joints of the pipeline can be implemented in practice and ensures uninterrupted operation regardless of the quality of wireless communications in the field or at an industrial facility with significant distances between the connection points.
  • the number of auxiliary operations necessary for monitoring and the time spent by the operator on the survey is reduced.
