Field Tests of Corrosion Rates

Extrin undertook in-situ corrosion rate testing at a WA Port. The project was to determine the efficacy of a new series sleeve wrapping system, with weight loss coupons placed below the sleeving systems of some steel support piles, and others had weight loss coupons fitted externally, to compare real time corrosion rates (control exposed coupons) versus the wrapped (protected) coupons. Results indicated the application of the tape wrap and sleeve approach reduced the extent of corrosion noted on the steel piles, where correctly applied.
