Abstract: The special type of fuel pressure pipeline was always operated in harsh condition. Corrosion perforation occurs frequently and the leakage hazardous medium is easy to cause serious disaster and environment pollution. In this paper, digital radiographic corrosion imaging technique on the pipeline was researched. Practical application showed that the method for the special type of fuel of pressure pipeline of large area scanning was a fast way, and it was an effective means for the pipeline corrosion detection.
