阴极保护在石化行业中的应用

Application of Cathodic Protection in Petrochemical Industry

随着原油品质的下降,油田开采设备、炼油装置、输送管道等石油装置设备面临越来越严峻的腐蚀问题。阴极保护在埋地输送管道、海洋平台防腐中发挥了重要作用,其可以有效避免或减缓管道腐蚀。根据不同的应用环境,外加电流的阴极保护和牺牲阳极的阴极保护两种方法单独或结合使用。

As the quality of crude oil declines,oil-field mining equipment,refinery equipment,and transportation pipelines were facing increasingly severe corrosion problems.Cathodic protection played an important role in the corrosion of buried pipelines and offshore platforms,and it could effectively avoid or slow down pipeline corrosion.According to different application environments,the cathodic protection of applied current and the cathodic protection of sacrificial anode were used alone or in combination.
