| 摘 要： | 针对原油长输管线在不停输时,由于挖开段的传热系数增大影响到站阃的压强,采用分段法在稳定的热力条件下计算不停输原油管道大修时压降,用C语言编制了计算程序;并举例加以说明,对开挖与不开挖时出站压力相同时的压降进行对比分析;确定不出现凝油事故时的最低出站压力.

| Abstract: | A model to calculate the variation of inter-station pressure drop is established when the on-line buried hot crude oil pipeline is repaired with the sectioning method in the condition of thermo-dynamic stability,by making the computer program in C language,and comparing the difference between excavation and no excavation under the same outgoing station pressure by using examples.Thus,a minimum outgoing station pressure is determind. |

| Keywords: | hot oil pipeline major repair pressure drop heat transfer coefficient outgoing station pressure |
