Storage tanks aboveground

Large steel aboveground storage tanks (ASTs) are located on large tank farms of oil producers (Fig. 3.15). Maintenance teams take care of external painting and both internal and external corrosion inspections. Corrosion inspection and protection of ASTs is important for the preservation of large capital investments, the reduction of maintenance and inspection costs, and the assurance of system integrity for release

Vaulted. Vaulted tanks are installed inside a concrete vault. The vault, itself a Hquid-tight compartment, reduces the fire protection requirements as the NFPA and the International Fire Code Institute (IFCI) recognize these tanks as fire-resistant aboveground storage tanks. The vault provides a two-hour fire wall, thermal protection that minimizes tank breathing losses and pollution, secondary containment, and baUistic protection.

While leak detection is not emphasized for aboveground storage tanks (ASTs), daily inspections, monthly inspections, annual inspections, and five-year inspections are legally required by the State of New York for AST owners or operators [14]. 

Abovegroimd Storage Tanks Aboveground storage tanks are classified as either field-erected or shop-fabricated. The Tatter is typically 190-m (50,000-gal) capacity or less and is able to be shipped over the highway, while larger tanks are more economically erected in the field. Whereas field-erected tanks likely constitute the majority of total AST storage capacity, shop-fabricated ASTs constitute the clear majority of the total number of ASTs in existence today Most of these shop-fabricated ASTs store flammable or combustible liquids at atmospheric pressure and have 45-m (12,000-gal) capacity or smaller.

Separation distances are also important. Aboveground storage tanks must be separated from buildings, property lines, fuel dispensers and dehvery trucks in accordance with the level of safety the tank design provides, depending upon whether they are constructed of traditional steel or are vault/fire-resistant.
