Abstract: China-Russia Eastern Gas Pipeline, as a landmark project of China's third generation of long-distance and largecapacity gas pipeline, is the largest single gas pipeline in the world and holds many new records in the history of pipeline construction, both in China and abroad. As a pilot project, the pipeline was built to be China's first intelligent pipeline model project. The basic connotation and key technologies of intelligent pipeline and intelligent pipeline network were systematically explained, and the key technologies and phased achievements supporting the "full digital handover, full intelligent operation and full life cycle management" of the pipeline were combed, so as to provide important guidance for continuously promoting the pipeline intelligent construction in China and assisting to build the large intelligent interconnected pipeline network. Furthermore, from the aspects of knowledge and technology, further thinking and suggestions were given on the technical essence of pipeline intelligence, digital infrastructure of pipeline, breakthrough of pipeline bottleneck technologies, intelligent brain of pipeline network, etc.
