Radiographic detection technology is a nondestructive detection technology widely used in industrial field and it
has unique advantages in qualitative defect detection and other aspects. According to the characteristics of defect imaging
technology, the development status of the major industrial radiographic detection technologies was compared, the technical
characteristics and advantages of Digital Radiography (DR) detection were clarified, and the requirements of the relevant
Chinese standards for radiographic detection of long-distance pipeline were summarized from the aspect of weld inspection
and qualification certification. In these standards, slight difference existed in the requirements of detection proportion, but
the requirements of DR and RT-F were consistent in defect assessment. Herein, the application of DR technology in long
distance pipeline at home and abroad were introduced, the technical problems of DR detection technology for application
in China were analyzed in the aspects of detection efficiency and economic benefits, selection of flat panel detector and
defect assessment, the future development trend of DR detection technology was prospected, and in combination with
the development trend of digital pipelines such as the China–Russia Eastern Gas Pipeline, the analysis indicates that
DR detection technology will play an increasingly important role in remote efficient assessment and detection big data
management and analysis, with broad application prospects.
