What is the minimum design service pressure for ASME LP-gas mobile fuel containers?

The minimum design service pressure for ASME LP-gas mobile fuel containers is governed by the requirements set forth in the NFPA 58 code, which ensures safety in the design and usage of these containers. For mobile fuel containers used for liquefied petroleum gas (LPG), a design service pressure of 250 or 312 psi is specified. This ensures that the containers can safely handle the pressures associated with liquefied gas and account for potential pressure increases due to temperature changes or other operational factors.

Choosing this design pressure is essential for maintaining safety standards during the storage and transport of LP-gas. It enables the tanks to operate effectively under varying conditions, thereby minimizing the risk of failure or accidents.

The other options provide pressure values that do not meet the established safety standards for mobile fuel containers as outlined in NFPA 58. Thus, selecting the correct range aligns with industry regulations and practices for ensuring safe operation and integrity of LP-gas systems.
