This library does not represent all tank styles, nor does it include all variations of tank conversion charts. All tank drawings are proprietary to Ace Tank & Equipment Co. (©2002-2004), and are linked here to provide customers and/or engineers with information specific to Ace Tank & Equipment’s tank design. These drawings do not reflect or imply the scope of tanks we can supply; rather, these are the most common tank styles and standard sizes offered with the individual style. Please note that these drawings do not reflect singlewall versions of the saddle-mounted or skid-mounted tanks. They are available; horizontal singlewall tanks typically are not used in larger than 1100 size and then are generally used only in home fuel oil and agricultural applications. This is not a hard and fast rule, however. You should always consult with the local authorities in your jurisdiction as to their requirements for both aboveground and belowground petroleum tank applications.

‘Inches-To-Gallons’ Tank Charts

By Underwriters Laboratory definition, most tanks are rated utilizing ‘nominal’ gallons. Essentially, the tank must have at least its listed capacity, but can exceed the listed capacity by 10%. In the case of doublewalled or insulated tanks, the dimensions listed below are for the primary or content holding tank. Outer dimensions on doublewalled or insulated vessels will be greater than the dimensions shown (for example, the Fireguard ® tank).

Horizontal tank charts are based on flat (non-dished) heads. These charts would be inaccurate for fiberglass tanks.

Vertical tank charts are based on flat bottoms and factor in the shell height only and not the conical tops.
