三相分离器外加电流阴极保护技术的改进与应用

Improvement and Application of External Current Cathodic Protection Technology for Three-Phase Separator

摘要: 本文通过三相分离器腐蚀类型及原因分析，提出了现阶段的内防腐技术的不足点，改进和完善了三相分离器外加电流阴极保护技术。应用于三相分离器本体保护是安全可靠的，并取得了较好的保护效果，尤其是防止点蚀，沟槽腐蚀效果明显。其保护度在95%以上，保护面100%。该技术投资少，效果显著，操作简单，管理方便，具有一定的推广价值。

Abstract: Through the analysis of three-phase separator corrosion types and causes, this paper proposes the deficiency of the anticorrosive technology at this stage, and improves and perfects the three-phase separator impressed current cathodic protection technology. Applying it in three-phase separator body protection is safe and reliable, and has got better protective effect, especially for the obvious effect to prevent the pitting corrosion and grooving corrosion. The protection degree is above 95%; protect area is 100%. The technique has the advantages of less investment, obvious effect, simple operation and convenient management, and has certain popularization value.
