PROTECTIVE COATINGS FOR STEEL PILING: CORRELATION OF RESULTS OF PARALLEL TET EXPOSURES AT PORT HUENEME AND GUAM.
Abstract
By means of a parallel study, seven coating systems, selected from a previous study at Port Hueneme, were evaluated by the U. S. Naval Civil Engineering Laboratory and by the Materials Testing and Evaluation Division, OICC, Marianas, as protective coating systems for steel piles. The systems were applied to both sheet and 'H' piles. The coated piles were driven and exposed in the surf at the Port Hueneme outer harbor and off Cabras Island in the harbor at Guam, and the condition of the coatings was inspected periodically. At the conclusion of a 30-month exposure at Port Hueneme and a 48-month exposure period at Guam, all seven systems showed some coating failure resulting either from the driving operation or the exposure conditions. Moderate to heavy damage to all systems was caused just above the mudline by the abrasive action of backwash in the surf at Port Hueneme. Coating failure, resulting in pitting, was observed in all coatings just below the mudline at Guam. On a combined performance basis a vinyl mastic, a phenolic mastic, and the Navy Saran coating are considered essentially equal. On a total applied cost basis the vinyl mastic and the Saran are preferred, with the Saran being slightly more economical. (Author)
