What happens if the test pressure exceeds the maximum working pressure?

When the test pressure exceeds the maximum working pressure, it may lead to damage within the system. Each gas piping system is designed to operate safely within specific pressure limits, known as the maximum working pressure, which should never be exceeded during testing or operation. Exceeding this limit can cause structural failures, leaks, or potential ruptures in the system, jeopardizing the safety of both the installation and its users.

Safety checks need to be performed under controlled conditions that comply with regulations, and while it might be necessary to test systems at higher pressures to ensure integrity, this practice must always stay within the specifications set by the relevant codes and standards. Thus, enforcing the maximum working pressure limit is crucial for the reliability and safety of gas piping systems.
