摘要:
Aiming at the operation safety of city gas polyethylene pipeline, this paper proposes a semi-quantitative risk evaluation technique to determine the possibility of risk failure and severity of consequence of PE gas pipeline. According to the basic procedure of semi-quantitative risk assessment, the failure probability and failure consequence of buried pipeline are analysed, and the safety risk level of each location of pipeline is evaluated comprehensively. The application of semi-quantitative risk assessment technology to gas polyethylene pipeline in a city in China shows that this technology can realize scientific management of pipeline according to risk level and further reduce the possibility of failure, so as to ensure safe, economical and reasonable operation of pipeline. © 2020 IEEE.
