What is the role of a gas line pressure test?

The role of a gas line pressure test is primarily focused on ensuring there are no leaks in the gas line system. This test involves pressurizing the gas line with a specific medium, often air or nitrogen, to verify the integrity of the system. During this process, if any leaks are present, the pressure will drop, indicating a breach in the system where gas could escape. This is critical for safety since gas leaks can lead to hazardous situations, including fire or explosions.

The test is not designed to evaluate the functionality of the gas meter, measure consumption rates, or regulate the flow of gas in appliances. Each of those functions serves a different aspect of gas supply and usage; however, they do not address the fundamental safety concerns related to leak detection, which is the primary purpose of conducting a pressure test in the gas line system.
