| Abstract: | In view of the low-throughput problem concerning the hot oil pipeline,this paper emphatically carried on an analysis of two aspects:hydraulic characteristic and thermal energy characteristic,described the situation that the temperature and the pipeline frictional resistance were lost along with the change of the distance and the throughput,and,according to this,summarized such problems as that the pipeline low-throughput movement can bring pipeline solidification,the increase of the surmounts spots,the phenomenon pipeline overpressure and the rise of expense.Then,in view of the above issues,it proposed concrete moethods and measure for reducing low-throughput pipeline unstable characteristic,thus providing reference for guaranteeing the safe operation of pipeline. |
