If you need to install a propane tank, you may wonder which variety you should choose: an American Society of Mechanical Engineers — ASME — or Department of Transportation — DOT — tank? Since both options are effective methods to store propane, your choice will ultimately depend on your unique needs. To help make the right decision, consider this convenient guide.

DOT Propane Tanks

Engineers craft DOT propane tanks to meet the Department of Transportation’s strict specifications. Their capacity is measured in pounds of water and is often utilized to power portable devices like barbecues. Generally, DOT propane tanks range anywhere from five- to 420-pound cylinders.

These tanks are unique because they can be safely and legally transported from one area to another when abiding by the guidelines stipulated by the Department of Transportation. For that reason, they tend to be more lightweight than ASME models. Due to the higher potential safety risks associated with DOT tanks, they must be re-certified 12 years after manufacturing and then again every five years. If you will need to move your propane tank for any reason, always choose a DOT cylinder.

ASME Propane Tanks

By contrast, ASME propane tanks must remain stationary. Professionals from the American Society of Mechanical Engineers stipulate these mechanisms’ boiler and pressure vessel safety standards, and their capacity amount is expressed in U.S. gallons rather than pounds. ASME tanks are often used to power devices like backup generators or pool heaters, which do not need to be moved.

They are constructed of thicker steel than DOT models and have the advantage of being able to store more propane. These propane tanks also have the added benefit of not requiring recertification after installation. If you will not need to move your propane tank or store mass quantities of the substance, then you should always select an ASME model.
