EMAT, Pipe Coatings, Corrosion Control And CP Shielding

A major issue in the pipeline industry is coating disbondment. A large percentage of external corrosion and stress corrosion cracking (SCC) has been and continues to be observed under disbonded coatings that shield cathodic protection (CP). This has been an ongoing issue with coated and cathodically protected pipelines since the beginning of using these two technologies.
