| 摘 要： | 采用管流实验法研究了321和316L两种典型奥氏体不锈钢在高温环烷酸中的腐蚀行为，并将实验结果与经验数据以及模拟结果对比分析。结果表明，不锈钢腐蚀速率随温度的上升而增加；同一温度下冲刷角90°时的腐蚀速率大于0°；试验数据与相近条件下API581数据以及在线监测数据对比结果相近；模拟结果与试验结果对比，验证了近壁处湍流强度越大的区域环烷酸腐蚀越严重。

| Abstract: | The corrosion behaviors of 321 and 316L austenitic stainless steel in high-temperature naphthenic acid medium were investigated by pipe flow.The influence of the erosion angle on naphthenic acid corrosion resistance of stainless steel was mainly analyzed.The results revealed that naphthenic acid corrosion rate increased with increasing temperature.The corrosion rates of erosion angle 90°is greater than 0°at the same temperature.The present experimental data and API 581,on-line monitoring data are close.Similar results were obtained after the test data compared with the empirical data of API 581 and on-line monitoring data.It was shown that naphthenic acid corrosion is most severe in areas of highest turbulence. |
