What is the maximum allowable pressure for natural gas distribution in residential applications?

In residential applications, the maximum allowable pressure for natural gas distribution is 0.5 psig. This pressure level is established to ensure safety and practicality in delivering gas to homes. At this pressure, the gas can be effectively and safely transported through service lines to residential appliances without risking leaks or dangerous conditions.

Residential gas appliances are designed to operate efficiently at this pressure, which is considered low pressure compared to higher pressure systems used for commercial or industrial applications. Operating at 0.5 psig helps to mitigate the risk of over-pressurization, which could lead to leaks or potential explosions.

Moreover, maintaining this pressure standard aligns with the requirements set forth by the National Fuel Gas Code, which outlines the safe use and distribution of natural gas. This code is crucial for ensuring that residential gas systems are reliable and safe for homeowners.
