What is the minimum pneumatic test pressure required for a hydrogen piping system?

• A. 3 psig
• B. 5 psig
• C. 10 psig
• D. 15 psig

Answer: (B)

The minimum pneumatic test pressure required for a hydrogen piping system is indeed 5 psig. This standard is dictated by safety and operational requirements specific to systems that transport or contain hydrogen gas. A pneumatic test at this pressure level helps ensure the integrity of the piping system and can reveal any leaks before it is put into operation, therefore enhancing safety. Testing at a lower pressure might not sufficiently verify the system's integrity, while higher pressures could pose unnecessary risks. Therefore, 5 psig is established as the minimum effective pressure for identifying potential problems within hydrogen piping systems, aligning with industry safety regulations and engineering practices designed to minimize leakage and ensure reliable operation.
