What type of test is recommended after the installation of gas piping?

After the installation of gas piping, a pressure test is recommended to ensure the integrity of the piping system. This test involves applying a specified pressure to the gas piping and maintaining it for a defined period. The primary purpose of a pressure test is to verify that there are no leaks in the system, which could lead to hazardous conditions, including gas accumulation and potential explosions.

A pressure test is crucial because it confirms that the system can withstand the operating pressures it will encounter during normal use. It also helps to identify any weaknesses in the piping, fittings, or connections that could fail under pressure.

While leak tests are valid for checking for losses of gas in the system after installation or maintenance, they typically follow a successful pressure test. The pressure test serves as a preliminary step to ensure that the entire system can safely hold gas at the required operating pressure before it is put into service. This order of procedures helps uphold safety standards and regulatory compliance within gas piping installations.
