针对大型储罐阴极保护的特点 ,在深入分析各种阴极保护方法在大型储罐防腐使用情况的基础上 ,比较出网状混合金属氧化物阳极具有技术先进、保护电流分布均匀、杂散电流小、接地电阻小、可靠性高、寿命长、便于施工等优点 ,选择在燕化公司炼油事业部新建 10万米3 原油储罐底板阴极保护中采用网状混合金属氧化物阳极
Aiming at the characteristics of cathodic protection of large storage tanks, based on the in-depth analysis of anticorrosive use of various kinds of cathodic protection methods in large tanks, it is found that the meshed mixed metal oxide anodes are technologically advanced, the distribution of protection current is uniform and the stray current is small , Grounding resistance is small, high reliability, long life, ease of construction, etc., choose Yanhua Refinery Division to build a new 100,000 cubic meters of crude oil tank bottom cathodic protection using mesh mixed metal oxide anode
