PROTECTION OF STEEL PILES IN A NATURAL SEAWATER ENVIRONMENT. PART 1

The corrosion behavior of protected carbon and low alloy steel piling in seawater is being investigated. Nine-three 'H' and pipe pile specimens, 35 feet long, were jetted into the Atlantic Ocean floor off the coast of Dam Neck, Va. The results of this study, which will take about 15 years to complete, will demonstrate which of the systems tested are best for protecting steel piles in seawater. Many types of protective methods are included in the investigation consisting of coating systems, cathodic protection by zinc and aluminum sacrificial anodes, and combinations of coatings and cathodic protection. At one-year intervals, polarization measurements and visual observations are made on the piles to determine the effectiveness of the coating systems and to measure the rates of corrosion. Potentials of cathodically protected piles are also measured. The first removal of one set of piles is scheduled for October, 1972, after exposure for approximately five years.
