大庆炼化公司储运厂由于整个系统长周期运行,内漏阀门过多,造成系统内部存在串量现象,影响产品质量。并且当系统内出现故障时,检修过程中无法处理管线拆加盲板,施工难度加大或无法施工,影响球罐的正常检定,给安全生产带来极大隐患影响长周期运行。利用装置全面停工的有利时机,对影响系统长周期运行的内漏阀门和界区阀门进行全面更换。
Daqing Refining & Chemical Storage and Transportation Company due to the long period of operation of the entire system, the internal leakage valve too much, resulting in the existence of the system within the string phenomenon, affecting product quality. And when the system fails, the maintenance process can not handle the blind pipe dismantling, construction more difficult or can not be construction, affecting the normal test of the tank, bringing great risks to the safety of production of long-cycle operation. Make full use of the equipment to stop the favorable opportunity, the impact of long-term operation of the system of internal leakage valve and the boundary valve to conduct a comprehensive replacement.
