For pipeline corrosion protection, anticorrosive coating of composite structure with3 coats of PE and sacrificialanodeprotection should be adopted.
管道防腐宜采用三层PE复合结构防腐涂层牺牲阳极保护。

At present, the sacrificialanode materials used for the protection of iron and steel, which are based of aluminum, zinc and magnesium alloy.
目前常用的保护钢铁设备的牺牲阳极材料有铝基合金、锌基合金和镁基合金三大类。

The sacrificialanode cathodic protection features no power source, simple management and even current distribution. It is well received especially on special shaped structure.
