油、气站场和大型储备库地下钢制管道及金属构筑物的阴极保护较长输管道要复杂的多,本文结合工程案例并依据投运后的实测实量数据,对多种保护方案进行了对比分析,提出站场阴极保护与相关专业特别是接地装置的关联度很高,制定保护方案时,要结合以往项目,在充分调研、评估的基础上进行,方案应经相关方会审认可后方可实施,使其既达到阴极保护的目的,又要经济合理并节能。
The long-distance cathodic protection of underground steel pipes and metal structures in oil, gas station yard and large storage depot is much more complicated. Based on the engineering case and the real measured real data after put into operation, a variety of protection schemes were carried out The comparative analysis shows that there is a high correlation between cathodic protection in the station and related majors, especially the grounding device. When formulating the protection plan, it should be combined with the previous projects and conducted on the basis of full investigation and evaluation. The plan should be approved by the relevant parties Implementation, so that it both achieve the purpose of cathodic protection, but also economical and reasonable and energy saving.
