Cleveland, OH Shop Fabricated Aboveground Tank Construction Standards

One key to clean freshwater is to prevent hazardous liquid spills from taking place in the first place. An important element to spill prevention is the safe storage of hazardous liquids in tanks that comply with national standards. Tanks come in many shapes and forms. Large tanks are erected in the field. Smaller tanks are produced in a factory and shipped to the site for installation. Shop-built tanks are made for underground installations and for aboveground installations. Aboveground tanks are either oriented for horizontal or vertical installation, and are produced in either cylindrical form or rectangular form. The tanks are capable of being designed and fabricated as pressure vessels, but are more typically vented to atmosphere. The tank can have compartments internal to the tank. Tanks are often secondarily contained. The tank can be insulated for fire safety or temperature control. Corrosion protection can be given to exterior tank bottoms in contact with soil or to the tank interior with special coatings and linings. Some aboveground tanks are even installed in an underground vault or room, without backfill. This paper presents tank standards covering shop-fabricated aboveground tan
