停输再启动是热油管道运行中比较普遍的工况,停输后管内油品会随着停输时间的增加而逐渐下降,进而导致油品流动性质受损。因此,为保证管道内油品能够安全可靠的运行,需要对管道停输时间、温度变化情况等参数进行详细了解。通过对热油管道停输再启动模拟试验进行研究分析,希望能够管道油品的安全运行提供一定的借鉴作用。 Stop-and-go restarting is a more common condition of hot oil pipeline operation. After stop-and-drop, the oil in the pipe will gradually decrease with the increase of stop-down time, resulting in impaired oil flow properties. Therefore, in order to ensure the safe and reliable operation of the oil in the pipeline, it is necessary to know more about the parameters such as the stopping time and the temperature change of the pipeline. Through the hot oil pipeline stop-restart simulation test research and analysis, I hope to be able to pipeline oil safe operation to provide some reference.
