In supercritical CO2 pipeline transport, the operation of pumps and valves often causes to enter a transient state. Accurately describing dynamic response in this state is crucial for making safety control decisions. This paper proposes nonisothermal one-dimensional flow model pipelines based on equations equipment characteristic equations. By comparison with experimental data, GERG-2008 equation, known its high accuracy, chosen calculate physical property parameters CO2. comparing several sets literature results show that errors are all within acceptable range, which verifies accuracy model. The study investigates hydraulic thermal changes under operating conditions, including valve closure, slow startup, sudden shutdown centrifugal pump. showed water-strike intensity one-third water but 12 times methane pipeline, requires sufficient attention. effect impurity composition strike significant, particularly when N2 content reaches 5%, at point maximum pressure decreases by 15.1%. addition, timing method shutoff significantly impact strikes. It recommended prioritize calculation piping cycles, determine closing time conjunction industry standards, use linear reduce pressure. Studies have shown startup or inlet can cause sharp fluctuations rate, new equilibrium will be established quickly. doping reduces magnitude rate pipeline. provides an essential foundation safe stable pipelines.
