Most propane dispensers include what type of tank for dispensing equipment?

The correct choice is the ASME storage tank, which is designed specifically for the safe storage and dispensing of propane. These tanks meet the safety standards set by the American Society of Mechanical Engineers (ASME), ensuring they can withstand high pressures and prevent leaks. ASME tanks are built with durable materials and are engineered to handle the physical stresses associated with propane use.

In addition, these tanks often include safety features such as pressure relief valves and are constructed to facilitate proper maintenance and inspections, crucial for the safe handling of LP-gas. Their size and design make them suitable for both commercial and residential applications where significant amounts of propane are stored and dispensed.

While steel tanks may be used in some contexts, they typically do not meet the specific pressure and safety requirements established for propane storage and dispensing. Polyethylene tanks are more commonly used for non-pressurized applications and are not suitable for LP-gas. Aluminum tanks, while lightweight and resistant to corrosion, do not have the robust design specifications of ASME tanks and are also generally used in specific applications like portable cylinders rather than stationary dispensing equipment.
