The research progress of corrosion mechanism at the top of wet gas pipelines is introduced.Based on the pearl shaped condensation top corrosion mechanism model,a calculation program for predicting the top corrosion rate has been developed.In a wet gas pipeline in Bohai Sea,a bead condensation top corrosion mechanism model was applied to calculate the top corrosion rate of the pipeline,and a comparative analysis was conducted with the corrosion rate predicted by internal inspection and the CO2 corrosion rate prediction results based on NORSORK M506.After analysis,it was believed that the analysis results of several methods were relatively close,which could assist management personnel in predicting the corrosion situation at the top of wet gas pipelines.
