摘　　要：为了进一步了解海上平台常用管道钢的腐蚀特性,尤其是在实际工作环境下存在的高温、高Cl-腐蚀情况,本文基于大型仿真软件COMSOL Multiphysics,在3.5%NaCl(质量分数)溶液中对Q235碳钢、304L不锈钢两种管道钢材进行了仿真模拟分析,从而为海上复杂环境中钢材的使用提供参考。In order to further understand the corrosion characteristics of pipeline steel commonly used in offshore platforms,especially the high temperature and high Cl-corrosion in the actual working environment.Based on COMSOL Multiphysics,two kinds of pipeline steels,Q235 carbon steel and 304L stainless steel,were simulated and analyzed in 3.5%NaCl solution,so as to provide reference for the use of steel in complex offshore environment.
