在石油化工管路设计中,当温度变化较大时,为了安全生产常设补偿器。对山洞油库(包括较大的半地下掩体式油库)内输油管路是否需要设补偿器则看法不一。 通过对14个山洞油库的调查发现,设补偿器的只有4个,占总数的28％;而不设补偿器的洞库多是70年代后修建的。这一调查虽不是大范围的,但就此问题确有商榷的必 In the petrochemical pipeline design, when the temperature changes is large, in order to safely produce permanent compensator. The different opinions on whether there is a need for a compensator in the oil pipelines in a cave oil depot (including a large semi-underground bunker depot). Through the investigation of 14 cave oil depots, it is found that there are only 4 compensators, accounting for 28% of the total; and those without compensators are mostly constructed after the 1970s. Although this survey is not a comprehensive one, it is indeed a matter of debate on this issue
