Gas pipelines can be routed using a variety of techniques, each of which has benefits and drawbacks. Problems with doing this process include the error brought on by the branches, the length of time required to travel the test route, and the requirement to turn off the gas in the test region. The acoustic approach is one of the ways to route polyethylene pipes for city gas. The city gas polyethylene pipe locating device has been conceived, constructed, and tested based on this methodology. A sound signal is supplied into the pipe of the apparatus created by joining the acoustic transmitter to the gas cylinder, and a geophone is then used to scan the target area.
