The maximum gas piping system design pressure for systems used inside of a building is established to ensure safety and compliance with various codes. In this context, a design pressure of 5 psig is permissible for most interior gas piping applications. This pressure range is appropriate for typical residential and commercial installations that require natural gas or propane systems, allowing enough capacity for appliances while minimizing the risk of overpressure situations that could lead to hazards.

Maintaining the maximum allowable pressure at 5 psig helps ensure that the installation adheres to safety regulations while still providing sufficient performance for gas-powered appliances. It's critical in maintaining an efficient and safe system, facilitating proper combustion, and ensuring that gas flows adequately to all necessary outlets within the building. Systems exceeding this pressure inside buildings can pose significant risks, including leaks or equipment damage, which is why careful adherence to these maximum pressures is paramount.
