Abstract:

Most utility lines under piers and wharves are made of iron or galvanized steel which become badly corroded when exposed to severe marine environment. The problem is compounded because of the difficulty of preparing good surfaces of these lines before coating because of their location and shape. CEL is investigating new and improved coating systems that can tolerate mimimum surface preparation, extend the service life, and reduce the maintenance cost. Various coating systems were subjected to 3 yr of in-service and atmospheric exposure tests. Of these systems, the grease-impregnated tape, Denso tape, was found to provide the best protection against corrosion attack under piers. Author
