What does a pressure test verify concerning gas piping?

• A. The gas flow rate
• B. The gas-tight integrity
• C. The installation date
• D. The size of the piping

Answer: (B)

A pressure test is an essential procedure carried out on gas piping to ensure the system is safe and leak-free. It specifically verifies the gas-tight integrity of the piping system. By subjecting the piping to a controlled pressure, any leaks or weaknesses in the structure can be detected. If the pressure remains stable during the test, it indicates that the piping system is securely sealed and capable of safely containing gas without any risk of leakage. The verification of gas-tight integrity is crucial for maintaining safety standards and preventing potential hazards, such as gas leaks that can lead to fires or explosions. This process does not measure the gas flow rate, confirm installation dates, or assess the size of the piping. Each of those aspects serves different purposes and requires different testing or documentation methods outside of a pressure test.
