In order to meet the development requirements of the data age, clustering, co-occurrence and emergence analysis was performed for the relevant literatures concerning pipeline integrity management at home and abroad in 2000–2020, and the knowledge graph of pipeline integrity management was constructed. Then, on the basis, the characteristics of research on pipeline integrity management were summarized with the research direction in this field predicted. The results show that the research scope of pipeline integrity management in China is gradually expanded and the research level is gradually deepened, which is internationally advanced. Generally, the keyword cluster is formed at the time close to that at abroad, but the research topics are quite different. The emerging words in recent years show that the research trend of pipeline integrity management in China will focus on the risk assessment, safety and high consequence areas, while the international pipeline integrity management in the next few years will be mainly developed in the direction of simulation, mechanics and failure possibility. Thus, the research results will provide some guidance to the research and development direction of pipeline integrity management in the future.(6 Figures, 5 Tables, 30 References) |
