混输海管二氧化碳腐蚀与缓蚀剂性能环路试验研究

Research on Carbon Dioxide Corrosion and Corrosion Inhibitor Properties in Mixture Transportation Pipeline by Loop Test

使用环路试验,研究了某一混输海管工况下流形、温度对二氧化碳腐蚀的影响,同时测量了现场应用的缓蚀剂的缓蚀效率。试验结果可解释混输海管的内检测数据,对于理解管道腐蚀现象,解决腐蚀问题具有指导意义。

The effect of manifold and temperature on the corrosion of carbon dioxide in a real mixed-transport pipeline is studied by using loop test.At the same time,the corrosion inhibition efficiency of the corrosion inhibitor used in the field is measured.The test results can explain the internal detection data of the mixed-transport sea pipeline,and have guiding significance for understanding the corrosion phenomenon of the pipeline and solving the corrosion problem.
