Propane is the most common form of liquefied petroleum gas (LPG) that can be used as a fuel in areas where no gas mains are installed. A byproduct of the oil refining process, it is compressed into a liquid for ease of storage and delivery. In a domestic storage tank, fuel vaporizes in the upper part of the vessel which can be tapped for use as a cooking and heating gas. Its pressure is regulated down to a level compatible with the appliances it runs. In cold climates, the ambient temperature is sometimes too low for the propane to vaporize fast enough, in which case a heat source, known as a vaporizer must be used. In its natural form, Propane has no smell and an odorant is added before distribution, for safety reasons.

The propane industry uses many different types and sizes of tanks, from 30,000 or more gallons at the distributor, to a barbecue cylinder. Hanson`s ASME propane tanks are built to 250# working pressure. Under normal circumstances, the vapor pressure at 100ºF is 172 psi.

Hanson Tank manufactures the following types of LPG tanks:
