摘要
为掌握热油管道停输再启动过程中温度和压力等参数的变化规律,在大庆试验基地进行了架空管道停输再启动模拟试验。试验结果表明,热油管道停输初期的温降速率比停输后期的温降速率快;管道停输再启动一定时间后出现压力的最大值,此后压力随着启动时间的延长逐渐降低,最后达到稳定状态;管道停输再启动后,出口温度先随启动时间的延长迅速增加,当管道运行一段时间后,管道末端的进站温度趋于稳定;管道停输再启动后,流量虽有一定的波动,但很快达到稳定状态。
To know well the variation law of such parameters as temperature and pressure,etc. during shut-down and restart-up of hot oil pipelines,simulation testing on shut-down and restart-up in an overhead pipeline is carried out in Daqing Testing Base. Testing results show that temperature drop rate for the hot oil pipeline in initial stage of shut-down is faster than that of the shut-down in later stage; after pipeline shuts down and restarts up for a certain time,maximum pressure will produce. After that,the pressure will be gradually decreased with the extension of restart-up period and tend to a steady state at last. After pipeline shut-down and restart-up,outlet temperature raises rapidly with the extension of restart-up time,after the pipeline is operated for some period of time,inlet temperature at pipe end goes to a steady state; although a certain fluctuation will be produced in flowrate,it will soon attain to a steady state.
