Most ASTs are constructed out of steel.Older tanks have riveted or bolted seams and newer tanks are welded. Fuel storage tanks must be vented so fumes can escape,reducing the potential for ruptures and collapses. ASTs should have cathodic protection,such as sacrificial anodes,to reduce corrosion.Above Ground Tank Construction Heartland Tank ServicesLarge Above Ground Liquid Tanks.Heartland Tank Companies specializes in construction of large above ground welded carbon and stainless steel liquid storage tanks.These large above ground storage tanks (ASTs) range in size from 100,000 up to 4 million gallons or 2,380 to 95,238 tons of liquid product.API Standards for Tanks - EnggCyclopediaWelded Steel Tanks for Oil Storage This document governs the construction of tanks storing hydrocarbon products at low operating pressure (up to 2.5 psig).{adinserter 1} API-651 Cathodic Protection for Above Ground Petroleum Storage Tanks Discussion on corrosion problems in above ground petroleum storage tanks and associated piping.
