Development of Tools to Estimate Actual Corrosion Growth Rates (Internal and External) of Gas Pipelines

项目名称：	Development of Tools to Estimate Actual Corrosion Growth Rates (Internal and External) of Gas Pipelines
摘要：	Southwest Research Institute (SwRI) recently completed a Pipeline and Hazardous Materials Safety Administration (PHMSA) project on Modeling Reassessment Intervals and is conducting a PRCI project on Internal Corrosion and has identified the needs, consistent with the current PHMSA BAA, for developing guidelines for more reliably predicting field corrosion growth rates. The main objectives of the proposed work are: (1) Improving the current existing internal corrosion rate model for wet gas pipelines and further verifying the model using field corrosion growth rate data, (2) Developing a thin-film internal corrosion model to predict corrosion rates in dry gas pipelines with gas quality upsets, and verifying the model using field corrosion growth rate data, and (3) Using the existing external corrosion model to predict external corrosion rates with including the effect of CO2 permeation from soil into a disbonded region through a holiday and through the coating itself.
