Abstract: To further increase the knowledge and understanding of the pipeline industry to its intelligent development, the status and trend of intelligent industry at home and abroad were investigated and analyzed, the relevant applicationcases of intelligent pipeline abroad were collected, and the results of work carried out in the construction of intelligentpipeline network in China and the practice of intelligent pipeline engineering in China-Russia Eastern Gas Pipeline weresummarized. The construction of intelligent industry (including the intelligent pipeline network) at home and abroad isgenerally in the primary stage of development, of which the development direction focused on the Internet of Things, digitaltwins, robots, intelligent equipment diagnosis, industrial internet platform application and so on. At the same time, the overallideas of data unification, system integration and standardization development were proposed. On this basis, the overallsolution of intelligent pipeline network with comprehensive systems and engineering operability was proposed. The overallstructure of intelligent pipeline network was established based on the aspects of business, intelligence and capability, andthe specific contents of each aspect were clarified. Besides, the result-oriented basic model for capability maturity evaluationof intelligent pipeline network was also proposed. On the principle of "from simple to difficult, from point to surface, andfrom part to whole", the developing route of "automatization, intellectualization and platformization" was put forward to theintelligent pipeline network. Finally, the problems existing in the construction of intelligent pipeline network were analyzedin depth, and the targeted development strategy was put forward.
