Method for inspecting pipes, and radiographic non-destructive inspection apparatus

摘要

This invention is intended to provide a pipe inspection method and apparatus that can be used to implement rapid, tomographic inspection of a pipe set up at a narrow location. The pipe inspection method of the present invention includes: a first step for scanning the pipe by translating a radiation source and radiation detector arranged opposedly to the pipe; a second step for the radiation detector to detect radiation that the radiation source has emitted, at given scanning distance intervals; a third step for creating a transmission image of the pipe, based on a radiation dose that the radiation detector has detected; and a fourth step for constructing a tomogram or stereoscopic image of the pipe, based on the transmission image. According to this invention, it is possible to provide the pipe inspection method and apparatus that can be used to implement rapid, tomographic inspection of the pipe set up at a narrow location.
