Steel tank firms shelved policy they said would protect tanks against corrosion

摘要

Steel tank manufacturers said eight years ago that they knew how to protect tanks from internal corrosion but then never implemented the strategy that they said would make tanks safer.rnThe Steel Tank Institute (STI) announced in April 2003 that, "in light of emerging research on microbial activity within tanks," its members would start installing zinc anodes or an internal coating on their tanks, effective June 30, 2003.
