中开线在运行过程中穿越黄河段下游站场气量突然下降,且压力也快速下降,根据掌握情况初步判断中开线首站至东明增压站间管线发生泄露,通过巡查最终确定了中开线在黄河主河道内发生破裂,为了避免类似事故的发生,主要是做好管线运行前期的各项工作。穿越河道的管线施工不论是在施工过程中,还是在管道的后期维护中,都存在很大的难度,因此控制和提高工程施工质量是确保管道后期运行安全的关键。 In the process of running through the open line in the downstream section of the Yellow River station sudden drop in gas, and the pressure is also rapidly declining, according to grasp the situation initially determine the start line to Dongming supercharger station pipeline leaks, through inspection finally identified in the open Line in the main channel of the Yellow River rupture, in order to avoid the occurrence of similar incidents, mainly to do a good job in the pipeline pre-operation. Pipeline construction across the river course is very difficult both in the construction process and in the post-maintenance of the pipeline. Therefore, controlling and improving the construction quality are the keys to ensure the safety of the pipelines in the later stage of operation.
