What is the minimum test pressure for newly installed gas piping?

The minimum test pressure for newly installed gas piping is established to ensure the integrity and safety of the system. A test pressure of 3 psig is required for newly installed gas piping. This pressure is sufficient to identify any potential leaks in the piping system before it goes into service, ensuring that all connections, joints, and fittings are secure and capable of safely handling the operational pressures.

Testing at this specified pressure helps in compliance with safety codes and standards that prohibit the use of installations that could potentially leak gas into the environment, which could pose a serious safety risk. This test pressure is part of the guidelines set forth by regulatory bodies, ensuring that the system can be safely pressurized during normal operations without failure.
