钢质储罐罐底外壁阴极保护设计

Difficulty Analysis of External Surface Cathodic Protection Design for the Bottom of Steel Storage Tanks

阴极保护技术在国内外已得到广泛的应用，区域性阴极保护是目前研究和应用的重点，其特点是保护对象不是单一的，而是一定区域内结构的复合体，一般是指运行生产中的储罐或储罐群。

Cathodic protection technology is used widely internal and external.Regional cathodic protection is the emphasis of study and application at present.Its characteristic is that the protected object isn't single one, but the complex of metal structure in the specified area. And usually it designates the tank(or tanks)to be used in production. Several difficulties which are met often in making cathodic protection for the bottom of tank or tanks are mainly analysed in this paper.
