Whenever stress corrosion cracking (SCC) is found on buried pipelines it is usually found in areas with disbonded polyethylene (P.E.) coatings. Interpretation of metal loss in-line inspection (ILI) logs can indicate areas that appear to be low-level metal loss similar to corrosion found under disbonded coatings. This identifies locations with a potential to form SCC, and as such, this analysis can be used as a useful method of SCC detection.
