I think there using the plastic as jacketing to stop signal bleeding like coaxial cable. |

Bedminster, NJ | I found out that plastic gas pipes are supposed to have a wire running alongside them, so the utility location folks can find the line. They must be using the wire to send the signal. |

Youngsville, PA | They have a wire for grounding out electricity that builds up from gas moving through the pipe. Gas moving through gas lines creates electricity and needs dissipated. |

| said by vpoko :Ehh? Why would they want people locating them with metal detectors? For the service people to find the exact location of the pipe without digging. This is done with water pipes also but I have seen them using a metallic tape similar to the one placed above buried power and telephone lines instead of a wire. |

It's actually not that easy to find with the average metal detector; which is why, most of the time, they put an RF signal on the wire.  |
