INDICATOR MINERALS FORMED DURING EXTERNAL CORROSION OF LINE PIPE

Pipelines suffer the threat of external corrosion where protective coa tings fail and create shielding disbondments. The sampling and analysi s of corrosion products to describe corrosion scenarios that occur und er shielding disbondments are reviewed. Understanding this environment is of interest both as input to risk assessment models and as part of current research into stress corrosion cracking on pipelines.
