Summary:The results of a two-year study of corrosion and corrosion protection characteristics of ductile iron pipe are presented. Included are field and laboratory evaluations related to short term and long term polarization rates under varying conditions; corrosion rate reduction and corresponding cathodic current criterion; and the corrosion protection benefits of the traditional, standard asphaltic shop coating. This information was then analyzed in conjunction with an extensive database from 1379 physical inspections of buried iron water lines. The result of the study is a risk based corrosion protection design strategy for buried ductile iron pipelines.
