What is the maximum design operating pressure for piping systems located inside buildings?

The maximum design operating pressure for piping systems located inside buildings is 5 psi. This standard is based on safety and operational guidelines to ensure that gas systems within enclosed spaces maintain the integrity necessary to minimize risks such as leaks or failures.

Piping systems that operate at pressures above this threshold can pose significant hazards, including the potential for gas leaks leading to explosions or asphyxiation due to gas accumulation. Setting the maximum at 5 psi allows for safe operation while still accommodating the needs of various appliances that may require propane gas for operation.

Understanding these pressure limits is crucial for compliance with building codes and safety regulations in the propane industry. This knowledge enables technicians and installers to design and implement systems that are both effective and safe for public use within buildings.
