Abstract: Construction design framework and specific contents of Sichuan Gas-to-East digitalization Transmission Pipeline based on integrity management are introduced. Combined with the integrity management concept, running of Sichuan Gas-to-East Transmission Pipeline, risk assessment, maintenance and repair etc. are integrated into 6 aspects: GIS pipeline management, pipeline environmental and geological disaster risk management, the third-party damage risk management, pipeline body defect risk management, gas stations and facilities risk management and pipeline integrity evaluation. Design contents and research issues about Sichuan Gas-to-East Transmission Digitalization Pipeline System based on integrity management are introduced. According to the practical application of the system, the advantages of the integrity management combined with digitalization pipeline platform are described, and the future development suggestions about the pipeline are put forward.
