Corrosion accounts for more than one third of the integrity problems on pipelines operating in Alberta. Gas pipelines in particular suffer the threat of external corrosion where protective coatings have failed and created shielding disbondments. This paper will review the sampling and analysis of corrosion products with a view to describing corrosion scenario`s which occur under shielding disbondments in the field. Understanding this environment is of timely interest both as input to risk assessment models and as part of the current research effort into stress corrosion cracking on pipelines.
