What is the appropriate pressure for conducting an air pressure test on a newly installed product piping system?

The recommended pressure for conducting an air pressure test on a newly installed product piping system is 50 PSIG for 1 hour while inspecting the joints for bubbles. This method is widely recognized as a standard practice because it allows sufficient time and pressure to identify any potential leaks in the system.

Conducting the test at 50 PSIG ensures that the system is evaluated under conditions that are representative of potential operational pressures, providing confidence in its integrity. During this testing period, inspecting the joints for bubbles is critical because any escaping air will create bubbles, indicating a leak. This proactive approach to leak detection is important for ensuring that the piping system is safe and compliant with regulations.

Setting the test at this specific pressure and duration helps ensure thoroughness and efficiency in identifying possible failure points, which is essential for the long-term safety and reliability of fuel storage operations.
