Question: 1 / 400

What does a pressure test evaluate in a gas piping system?

The efficiency of the gas flow

The integrity and safety against leaks

A pressure test is specifically designed to evaluate the integrity and safety of a gas piping system, particularly in terms of identifying any potential leaks. This procedure involves filling the system with a specific pressure medium, often air or an inert gas, and monitoring for any drops in pressure that would indicate leakage. Ensuring that there are no leaks is critical not only for the efficiency of the gas system but also for the safety of the environment and personnel around it.

While compliance with installation codes or operational pressure levels may be indirectly observed during such tests, the primary objective remains to ascertain the system's seal against leaks, demonstrating its robustness and reliability in safely containing gas. Thus, the evaluation of integrity and safety against leaks is the key focus of a pressure test in a gas piping system.
