Gas Fitter Practice Test

What does a gas fitter use to connect two pipes in a gas system?

1. Welds

2. Couplings

3. Tapes

4. Screws

The correct answer is: Couplings

A gas fitter typically uses couplings to connect two pipes in a gas system. Couplings are specialized fittings designed specifically for joining two sections of piping, allowing for a secure and effective connection that can handle the pressures and operating conditions found in gas systems. Welds, although they can be used in some scenarios for metal piping, are not the most common method in gas fitting due to the need for specialized skills and equipment to perform them safely. Tapes may be used for sealing joints, but they do not provide a structural connection between pipes. Screws may be utilized in some situations, but they are generally not a standard method for connecting gas pipes, as they can compromise the integrity of the piping system. Couplings ensure a reliable and safe connection, which is paramount in gas installations to prevent leaks and ensure efficient operation.
