| Abstract: | Pitting is an important factor to influence residual lifetime of Oil & gas pipelines, Predicting the pitting depth growth behavior in Oil & gas pipelines is one of the critical procedures to assess residual lifetime of pipelines, Based on the characteristics of time series analysis in handling with dynamic data, A time series analysis model is established on pitting corrosion observation data series, And the validity of the method is analyzed with an instance. The results show that it is feasible to use time series analysis to predict the pitting depth growth in Oil & Gas pipelines. |
