Types of Propane Tanks

Propane storage containers are made in many sizes and shapes for both stationary and mobile use. Both types are designed to hold propane in its liquid form, which means that the container is pressurized. It’s important to know which type you own because there are specific requirements for each. Rules governing the installation of propane containers are enforced at the national, state, and local levels ensuring all applicable codes and regulations are adhered to for the safety of consumers and the general public. Steel stationary tanks are commonly installed both above- and underground at homes or businesses to supply fuel to all propane-powered appliances in the structure.

Common Types of Propane Tanks

  • American Society of Mechanical Engineers (ASME) tanks are a common type used to supply fuel to the home. These tanks are typically installed horizontally and range in size from 120 to more than 1,000 gallons.
  • Department of Transportation (DOT) cylinders that provide fuel for homes are called stationary or exchange service cylinders. These are installed vertically and tend to be smaller in size than an ASME type.

Smaller DOT cylinders commonly used for all types of work and recreational equipment, outdoor living amenities, and forklifts are called portable cylinders. These can be various sizes and made of different materials like steel, aluminum, or composite materials.

Disposable Cylinders

Disposable cylinders are small cylinders, typically containing one pound of propane that can be used for camping or soldering. These types of cylinders generally are disposable, but some approved cylinders can be refilled.

There are many requirements for proper installation of propane containers as well as laws and procedures governing the repair of containers and systems they service. Unlicensed or unqualified individuals should never attempt to make repairs or modifications to their propane containers, and installation and maintenance should only be performed by those who are familiar with the codes and regulations regarding propane containers.
