The pipe at dig sites 2 and 3 were free from internal corrosion, w hich may ser ve as vali d ation of th e assessment. Conclusions Based on the results presented and dis- cussed in the present work, it can be con- cluded that flow modeling is a powerful tool to assess pipeline integrity due to internal corrosion. If the locations predicted by flow modeling have not corroded, than other locations of the pipeline that are less likely to accumulate water can be considered cor- rosion free and do not require further exam- ination. The ICDA process helps reduce the likelihood of integrity threats and helps to ensure compliance with U.S. regulations.
