成品油库主要储存汽柴油等轻质油品,在管线未设保温层时,管线内液体容易因温差产生压力,严重的会导致管线设备的损坏,合理选择有效的泄压方式,泄压位置以及适当的整定压力,能有效的减少管线热膨胀的后果。本文对成品油库不同区域的泄压方式进行解析,结合久长油库泄压系统设计说明泄压整定压力的设置原则。 The finished oil depot mainly stores light oil products such as gasoline and diesel. When there is no insulation layer in the pipeline, the liquid in the pipeline will easily be pressured by temperature difference, which will seriously damage the pipeline equipment and reasonably choose effective pressure relief mode, pressure relief position and Appropriate setting pressure, can effectively reduce the pipeline thermal expansion consequences. In this paper, the pressure relief methods of different regions of finished oil depot are analyzed, and the principle of pressure relief setting pressure is explained with the design of long depress depressurization system.
