摘要
结合站场埋地管道及设备的特点,通过管道防腐方案的比选,确定了本工程站场管道的外防腐方案为3层PE外防腐层,对于不规则管件及设备采用价格较高,防腐性能较好的粘弹体防腐材料。针对现场情况以及区域性阴极保护的实施前提,对新建站场是否实施区域性阴极保护进行了说明。
Based on characteristics of buried pipelines and equipments in a gas transmission station,through comparison of external anticorrosive schemes,three-layer PE external anticorrosive coating as the external anticorrosive scheme was determined.For irregular pipe fittings and equipments,visco-elastic material with good corrosion resistance was used as anti-corrosion material.According to the site condition,whether to implement local cathodic protection was discussed.
