At what pressure do propane tanks typically operate?

Propane tanks typically operate at a pressure of 10 PSI when checked at ambient temperatures. This pressure is a standard operating point for many propane applications, as it allows for efficient transfer and utilization of propane without risking the integrity of the tank or the connecting systems.

At 10 PSI, the liquid propane is able to vaporize and supply the necessary vapor pressure to ensure proper combustion in various appliances and systems, such as furnaces, stoves, and engines. Understanding this operating pressure is crucial for technicians, as it aids in the assessment of system functionality and safety.

Other options, like 20 PSI and 30 PSI, are higher than what is generally utilized in standard propane systems and could be associated with specific applications or tanks designed to operate at those pressures, but they are not typical for general use. Additionally, the pressure of 14 inches water column (WC) reflects a different measurement, commonly used in gas delivery systems, but does not represent the pressure at which propane tanks typically operate.
