What is the maximum permitted filling density of a cylinder with Liquid Propane?

The maximum permitted filling density of a cylinder with Liquid Propane is 80%. This safety standard is established to allow for the expansion of the liquid propane as temperatures rise, preventing excessive pressure buildup within the cylinder. Propane expands significantly when heated, so leaving adequate space inside the cylinder allows for this thermal expansion without risking the integrity of the cylinder or triggering a safety relief mechanism.

In addition, the 80% filling density also considers safety margins and ensures that cylinders remain within the guidelines set by regulatory authorities for safe handling and transport. This is crucial, as exceeding this limit may lead to dangerous situations, including the risk of leaks or cylinder rupture under high-pressure conditions. Understanding this filling density is an essential component of safely managing propane systems in various applications.
