在化工行业生产经营建设中，化工管道运行水平与全寿命周期可直接影响到实际生产期间的综合效益。为进一步增强化工管道防腐性能，需要配合使用适宜的电化学防护技术。基于此，本文以化工管道腐蚀影响与种类为切入点，阐述电化学腐蚀机理，提出电化学防护技术在化工管道防护中的具体应用要点，以供参考“,”in the production, operation and construction of chemical industry, the operation level and life cycle of chemical pipeline can directly affect the comprehensive benefits during the actual production period. In order to further enhance the antiu0002corrosion performance of chemical pipeline, it is necessary to use appropriate electrochemical protection technology. Based on this, this paper takes the chemical pipeline corrosion impact and types as the breakthrough point, expounds the electrochemical corrosion mechanism, and puts forward the specific application points of electrochemical protection technology in chemical pipeline protection, for reference.
