  The radiation piping diagnostic system according to the present embodiment will be described below with reference to the accompanying drawings. In the following description, a case where the radiation piping diagnosis system is applied to piping diagnosis in a piping system of a plant facility and an underground piping system will be described. However, the radiation piping diagnosis system according to the present embodiment is not limited to this, but can be applied to any one of the plant facilities and underground piping systems, or can be applied to factories, power plants such as nuclear power and thermal power, airports, or stations. It can be similarly applied to the radiation diagnosis of piping systems in such facilities.

  FIG. 1 is a system configuration diagram of a radiation piping diagnostic system according to the present embodiment. As shown in FIG. 1, the radiation piping diagnostic system according to the present embodiment includes an internal inspection device 11, a thickness measuring device 12, and a piping sorting device 13 as piping inspection devices. The internal inspection device 11 and the thickness measurement device 12 are used in the plant piping system 15 of the plant facility, and the internal inspection device 11, the thickness measurement device 12 and the pipe selection device 13 are embedded in the underground piping system 16 embedded in the ground. Used in In the radiation piping diagnosis system, diagnosis is performed by performing management, analysis, analysis, etc. of piping based on the radiation inspection results of the devices 11 to 13 for a plurality of piping constituting the plant piping system 15 and the embedded piping system 16. .

  The internal inspection apparatus 11 includes an X-ray source and a radiation detector that are opposed to each other with a pipe interposed therebetween. As the X-ray source, a high-efficiency carbon structure type X generator tube that does not require preheating and is easy to reduce in size and weight can be used. The radiation detector detects X-rays emitted from an X-ray source, and for example, a CsI detector or a NaI detector can be used. The radiation detector receives X-rays emitted from an X-ray source and transmitted through a pipe, and measures a count value obtained by counting the incident X-rays. This measurement is performed for each predetermined range (for example, for each pixel) on the detection surface of the radiation detector, and the measurement result is processed to output an X-ray projection image of the pipe as inspection result data. Therefore, it is possible to generate an X-ray projection image in which a dent or a bump on the inner surface of the pipe appears based on the detection result of the internal inspection device 11, and it is possible to inspect the inner surface of the pipe using the X-ray projection image.

  As another example of the radiation detector, a plate coated with a stimulable phosphor capable of accumulating and recording X-ray images on one side of an organic film may be used. In this configuration, when X-rays are irradiated, energy is accumulated in the phosphor, and the phosphor emits light according to the amount of radiation absorbed. Then, after X-ray irradiation, the plate is scanned with laser light to read an X-ray projection image.

  The internal inspection device 11 may be attached to and detached from the pipe at a desired inspection time, or may be continuously installed at a specific position of the pipe and inspected periodically or at the timing of user operation. .

The thickness measuring device 12 calculates the pipe thickness based on the irradiation condition of the radiation from the radiation source, the measured count value, and the like, and outputs it as inspection result data. In this calculation, it is possible to measure the thickness from above the heat insulating material or the like by obtaining a value corrected by the conditions for the heat insulating material or exterior material outside the pipe and the contents in the pipe. Thereby, the work of removing and attaching the heat insulating material can be omitted, and the thickness can be measured without stopping the plant or the like while the fluid is flowing in the pipe.

  Also in the pipe sorting apparatus 13, a radiation source that emits radiation such as γ-rays and a radiation detector for detecting the radiation dose from the radiation source are arranged opposite to each other across the pipe, and the radiation dose transmitted through the pipe. (Count value) is detected by a radiation detector. In the pipe sorting apparatus 13, the predicted value of the count value is calculated in advance for each use of the pipe, that is, in the case of a gas pipe (content is gas) and in the case of a water pipe (content is water). Then, based on a comparison between the predicted value and a count value that is an actual measurement value in the radiation detector, the usage of the pipe is selected, and the selection result is output as detection data.

A process of displaying M3 may be performed. It is preferable that the marks M1 to M3 have different display modes according to the difference in the inspection result data associated with the inspection position information.

  That is, in the present embodiment, the display processing unit 36 adds inspection position information (for example, the three-dimensional and two-dimensional piping system diagrams (FIG. 3A and FIG. 3B) of the plant piping system 15 stored in the piping information storage unit 33. , Latitude / longitude, address information, and worker input information), conversion of information for specifying inspection position information on the piping system diagram is performed. This process may be performed as appropriate, but it is preferable to update and store the data specifying the inspection position information in the piping system data.

Moreover, there is no restriction | limiting in particular about the numerical value, dimension, material, and direction which were demonstrated by the said embodiment. Other modifications may be made as appropriate without departing from the scope of the object of the present invention.

  For example, the piping information storage unit 33 and the design data storage unit 35 are not limited to the configuration included as a part of the analysis server 22 and can be connected as an external hard disk or communicated with the communication network 24 by wire or wirelessly. You may install as a state.

  Further, in FIG. 5, it is not necessary to inspect and accumulate all the inspection result data and diagnosis result data for one inspection position information, and some of the inspection position data may not be accumulated depending on the inspection state or the like. . Moreover, it is good also as what is not displayed partially about each display of FIG. 3 about one test | inspection position information.

  The management of the piping state by the piping management unit 32 may be based on at least the inspection result data, and may be performed without using other data and information.

  The display screens 20a of FIGS. 3 to 5 are not limited to those displayed on the terminal device 20, and may be displayed on other external devices. For example, in a plant such as a power plant, a display similar to the above-described display screen 20a is performed on the display of the central supervisory control device in the central control room designed to collect a large amount of information and perform all operation operations. The pipe state may be managed.
