| Abstract: | In order to investigate the research & development and application status of X80 pipeline steel and their existing problems, we reviewed the main factors affecting the performance of X80 pipeline steel, as well as the research progress and technical challenges in the development of X80 steel pipeline. The metallurgical characteristics and microstructure of X80 pipeline steel were analyzed in detail, its welding technologies, welding metallurgical characteristics and properties were reviewed, and its mechanical performance and mechanical characteristics were summarized. In particular, the failure mechanisms of X80 pipeline steel in the service environments were discussed, including corrosion, hydrogen induced cracking, failure of weld zone and strain aging. Finally, the technical challenges affecting the development of X80 pipeline steel were analyzed to ensure the safety and efficiency of the oil/gas transportation and the sustainability of oil/gas pipeline development.(1 Figure, 8 Tables, 86 References) |
