A survey of manufacturing and installation methods, standards, and specifications of factory-made steel storage tanks and appurtenances for petroleum, chemicals, hydrocarbons, and other flammable or combustible liquids. It chronicles the trends towards aboveground storage tanks, secondary containment, and corrosion-resistant underground steel storage systems.Shop-fabricated tanks: introduction - a history of storage tank systems; historical perspective on standards and codes; history of the uniform fire code; quality control on USTs and ASTs; UST and AST fabrication; storage tank specification considerations; to bury or not to bury - steel tank technology decisions. Underground storage tanks: UST design - the wall thickness question; development of UL standards for underground steel tank safety; development of ULC standards for underground storage and handling of flammable and combustible liquids; federal UST regulatory programme; steel UST technologies; underground storage tank installation; UST performance; corrosion and cathodic protection on underground storage tanks; how to specify UST system equipment. Aboveground storage tanks: AST design; development of UL standards for aboveground steel tank safety; development of ULC standards for aboveground storage and handling of flammable and combustible liquids; secondary containment for noninsulated steel aboveground storage tank systems; AST environmental regulations; plan review and inspection of aboveground storage tanks; aboveground storage tank installation; how to specify AST system equipment.
