What is the maximum allowable operating pressure for undiluted LP gas systems as per NFPA regulations?

The maximum allowable operating pressure for undiluted LP gas systems as per NFPA regulations is 20 PSI. This specification ensures that the systems operate within safe and effective limits to minimize the risks associated with handling and using liquefied petroleum gas. The 20 PSI threshold is established to ensure that all components within the gas delivery system, including piping, fittings, and appliances, are designed to safely handle the pressure without compromising safety or efficiency.

Understanding this pressure limit is crucial for professionals working with LP gas systems, as exceeding it could lead to dangerous situations such as leaks, equipment failure, or even explosions. The NFPA establishes these standards based on extensive research and safety considerations, aimed at protecting both workers and consumers from potential hazards associated with high-pressure gas systems. Adhering to these regulations is essential for maintaining compliance and ensuring safe operations in any setting where LP gas is used.
