71 LP Gas Containers and Systems Pressure Regulators There are 13 different types of regulators referenced in NFPA 58. Reduce pressure from high tank pressures (80 to 250 PSIG) down to the low operating pressures of equipment (1 PSIG).

72 LP Gas Containers and Systems Pressure Regulators First Stage Second Stage

73 LP Gas Containers and Systems Pressure Relief Device All DOT Cylinders and ASME Containers used for LP Gas are equipped with pressure relief devices that are intended to prevent failure of the container due to overpressurization. Occurs most often when the container is liquid full. When a container is liquid full, a small increase in temperature can cause a large increase in pressure. Although opening the pressure relief valve will prevent the container from failure due to overpressure, the release of LP Gas may also present a hazard. Pressure relief valves are also found in segments of hose or piping where liquid can be trapped between valves.
