What is an ASME tank?
An ASME tank is a stationary propane storage vessel of 120 gallons or larger that meets American Society of Mechanical Engineers pressure vessel codes and is designed for permanent outdoor installation at a property.
An ASME tank holds propane for stationary use at a fixed location, typically a residence, farm, business, or industrial facility in Florida. These tanks are manufactured to the pressure vessel standards set by the American Society of Mechanical Engineers and bear an ASME stamp certifying compliance. Most ASME tanks start at 120 gallons and go much larger, making them suited for extended storage and regular delivery refills rather than portable transport.
The core difference between an ASME tank and a DOT cylinder lies in purpose and regulation. DOT cylinders, stamped by the U.S. Department of Transportation, are portable tanks designed for movement and temporary use, such as grill bottles or small heaters. ASME tanks are stationary vessels permanently installed above or below ground, secured in place, and inspected under different safety and operational rules. ASME tanks typically feature thicker steel walls, larger capacity, and lower pressure ratings than DOT cylinders because they do not need to withstand the vibration and handling of transport.
Propane suppliers across Florida install and maintain ASME tanks for customers needing reliable bulk storage. These tanks require proper siting, ventilation, and distance from structures per Florida Fire Code. When selecting an ASME tank installation, property owners should verify that the supplier holds proper licensing and can handle delivery logistics, leak detection, and safety compliance. Find propane tank installation providers in your area to assess options and ensure code-compliant setup.
