参考丽水36-1项目导管架设计建造,对导管架阴极保护设计的两种方法,即导管架飞溅区以下只采用牺牲阳极的阴极保护设计方法和导管架飞溅区以下采用涂装和牺牲阳极联合的保护方法。分别从设计方法、成本、施工时间、施工难点等方面进行对比分析,得出符合项目设计、施工要求的设计方法,以期优化导管架阴极保护设计,降低项目施工难度和施工成本。
Reference Lishui 36-1 project jacket design and construction of the cathodic protection of the jacket design of the two methods, namely jacket splash zone following the sacrificial anode only cathodic protection design and jacket spatter below the coating and sacrificial anode combination The protection method. From the aspects of design method, cost, construction time, construction difficulties and so on, the design methods that meet the project design and construction requirements are obtained, in order to optimize the cathodic protection design of jacket and reduce the construction difficulty and construction cost.
