The hydrostatic test pressure on a hydrogen piping system shall be not less than which of the following?

• A. 75 psig
• B. 100 psig
• C. 150 psig
• D. 50 psig

Answer: (B)

The hydrostatic test pressure for a hydrogen piping system is determined to ensure that the system can withstand pressures beyond its normal operating conditions without failing. A requirement of 100 psig is established to safeguard against potential leaks or failures that could arise from operational pressures exceeding normal levels. Hydrostatic testing involves filling the piping system with liquid, generally water, and pressurizing it to specified levels to check for integrity and leaks. Testing at this specified pressure helps confirm that the materials and joints of the piping system are capable of safely handling the operational stresses they will encounter. Establishing a minimum hydrostatic test pressure of 100 psig reflects industry standards aimed at ensuring the safety and reliability of hydrogen systems, which require stringent testing due to the unique properties and risks associated with hydrogen gas. This specified pressure level ensures that small defects that may compromise the system won't go undetected, contributing to the overall safety when hydrogen is used.
