In this article,it introduced the application status of X-ray digital radiography (DR) technology in other fields and its working principle. Through many tests,continuously adjusted and improved the relevant technology project,it realized applying DR technology to steel pipe quality inspection. Compared with the conventional X-ray detection,the result showed that the sensitivity and the spatial resolution are better than image intensifier,which is close to conventional film. And imaging time and image post-processing time are short,it increases detection efficiency,reduces security risk,and can fully meet technical requirements of relevant standards.
