- 摘要:
- 为抑制大型油气站场地下金属构筑物的腐蚀,确保企业正常的生产经营活动,有必要了解站场阴极保护的技术特点,明确应用中影响保护效果的技术难点。基于施加在油气站场管网密集区的阴极保护存在着保护电流需求大、阳极床设计困难、对外部的干扰和屏蔽现象较为复杂等问题,通过分析站场阴极保护实施中的关键技术,明确了线性阳极作为辅助阳极有着其他传统阳极床所不具备的优势,可以有效控制干扰、减缓屏蔽。站场阴极保护是保证大型油气站场安全生产的重要防腐措施,线性阳极对提高站场阴极保护的防护效果意义重大。
To inhibit corrosion of underground metallic structures at large oil and gas station and ensure normal production and operation of enterprise, it is necessary to understand the technical characteristics of cathodic protection for plant and identify technical difficulties affecting protective effect in application. Based on the issues of cathodic protection such as high demand for protective current, difficult design for anode bed, interference and shielding to the external in highly concentrated pipeline net-work areas, it is defined that linear anode as auxiliary anode, compared with other traditional anode beds, enjoys more advantages that can control interference, slow down shielding effectively by analyzing the key technology of cathodic protection implementation for plant. Cathodic protection for plant is an important anticorrosion measure to guarantee safe production in large oil and gas stations and linear anode is of great significance for improving the protection of cathodic protection in plant.
