Résumé : |
Cathodic protection (CP) is widely used internationally as a major corrosion mitigation technique in pipeline integrity. The use of protective coatings in conjunction with cathodic has been an extensive record of proven performance in the protection structure including underground pipelines, ships, underground storage tanks, pipings, and tank bottoms. The use of both a protective coating and a cathodic protection system presents unique design, installation and maintenance consideration. However, if the coating is not properly chosen there will be premature failure of adhesion between a coating and the material substrate which directly attributed to cathodic protection conditions. This paper will discuss about the correlation of vapour permeability with the extent of cathodic disbondment of different coating materials under accelerated conditions. |
