A CORROSION PREDICTIVE MODEL FOR USE IN FLOWLINE AND PIPELINE INTEGRITY MANAGEMENT

摘要

A model has been developed which can predict the corrosion rate in gas and oil flowlines and pipelines. The Windows based program describes the physical and chemical conditions inside of a pipe. This model is capable of predicting the corrosion rate in systems containing CO_2, H_2S, organic acids and bacteria. The model also predicts the occurrence of "top of the line" corrosion, wettability conditions and can describe flow dynamics in large diameter pipelines. A new addition to the model is a risk assessment component, which allows for integrity management of the system.A number of field cases have been presented to show the utility of the model. The physical model has been compared to PipePhase and the results have been very satisfactory.
