External corrosion protection systems for flammable and combustible liquids underground storage tanks

This paper gives an overview on the evolution and standards development of the external corrosion protection systems used for flammable and combustible liquids underground storage tanks (USTs) in North America. The paper first describes the different types of corrosion protected USTs for flammable and combustible liquids in North America. It then reviews the advantages and disadvantages of each of the corrosion protection systems used. Finally, it looks forward to some of the technical trends in the North American UST industry and the standard certification process for underground tank external corrosion protection, with updates on the technology and standards in the international UST industry.
