CP Shielding and Pipeline Coatings

Shielding of cathodic protection (CP) by pipeline coatings poses a serious threat to pipeline integrity.  The difficulty in pipeline coating selection to avoid shielding is that the same properties that make a pipeline coating a good corrosion mitigation material can also lead to CP shielding. The key to proper coating selection is to select a coating that has the necessary properties to provide good corrosion protection but also one that, when disbondment and failure occurs, fails in such a way to allow effective cathodic protection.
