Selection of Pipeline Flow and Internal Corrosion Models

The purpose of this report is to assist users in making informed technical decisions regarding flow models used to predict the possible locations of internal corrosion and corrosion models used to predict the severity of internal corrosion at those locations. Flow and corrosion rate prediction models can also be used in conjunction with inline inspection (ILI) data to establish the frequency of ILI runs by predicting the anticipated metal loss. This is applicable to piggable pipelines, for which periodic inspections using ILI tools are typically implemented.
