poly gas pipe
what is the difference between the yellow polythylene
pipe designed for gas, and garden variety black polythylene pipe? I am not planning on using the black stuff, but just curious, as the gas pipe seems more expensive. |

poly gas pipe
Just check the wall thickness, it is a different product entirely. If I am
correct, it is not just polyethylene but a different type or mix of plastic. Finally, it is color coded to identify it as gas pipe. Connections are made with special fittings and/or are plastic welded. wrote in message oups.com... what is the difference between the yellow polythylene pipe designed for gas, and garden variety black polythylene pipe?

Do you have any reason to not allow the plastic gas piping? Your friend
sounds like a nut, delaying a whole public works project out of fear of plastic gas pipe in his front yard |

"MC" wrote in message What surprised me is how no one with the gas company there was even concerned about all the gas leaking out before they got it clamped and while digging it up. Not much concern really. Once in open atmosphere, it is less harmless than most people think. Danger comes from the right concentration in an enclosed space. Ever watch them weld on a gas line that has gas in it? |

Cheers, Wayne With no ignition source, the concentration of gas from an open residential gas line is not a health problem. Yes, It stinks. The real risk is ignition, and the ignition source will need to be CLOSE to the open gas line to ignite it. |

poly gas pipe
Plastic gas line was brand new 25 years ago, most leaks are from
rusting in metal lines, that go unnoticed till something bad happens or the stink is noticed which is why the odorant is there. the big thing about gas leaks is they follow the lines so in the mddle of the street gains little. myself I would rather have plastic perhaps encased in a heavy outer cover like 4 inch PVC sewer line for mecanical protection |

The smell is added for that. In open space the amount of gas should be a lot for ignition. |
