Storage Tanks

A.P.I. (American Petroleum Institute) vertical liquid storage tanks have cone or domed tops and flat bottoms. Most of our A.P.I. storage tanks are built per A.P.I. 650 appendex "S" for "shop fabricated" stainless storage tanks. These are low pressure tanks.

A.S.M.E. (American Society of Mechinical Engineers) storage tanks are usually set off the ground on legs or skirts. Vertical storage tanks are mounted on side lugs, and horizontal storage tanks on saddles. They will usually have domed "ends" and some have cone bottoms. These storage tanks can be designed to handle internal and external pressure for the storage of air or gases like CO2.
