Brazing VS Soldering copper gas pipes
I have installed a Gas stove and had to run pipe to the kitchen.
I tapped into the existing copper pipe with a copper T. Ran copper to Black pipe which is what comes out of the floor in the Kitchen for the Gas Stove to hookup to. The copper fittings that I put in were soldered using standard plumbing solder. There have been no leaks and this has been in place a couple of months now, but I've read somewhere that soldering is only for water and not gas. What are the problems with soldering for gas pipes? Is this setup dangerous? |
I've soldered, brazed and done some light welding - but I've never worked on home gas lines other than working with threaded pipe. If I were in your situation, I'd begin by phoning my local zoning folks and asking them about code requirements and zoning rules. These folks can be extremely useful when seeking advise. Just recently I talked with them and got good advise before I purchased my framing nailer which uses clipped-head nails. (zoning varies with respect to accepting clipped-head nails). Obviously, brazing is stronger and not much more difficult. |

Is this setup dangerous? Copper *is* permitted in some parts of the country for gas lines. But soldered (or brazed) joints are not allowed. Only flare-fitting connections should be used and only soft copper tubing. The reasoning is that soldered joints can be difficult to make leak-free (and leaks don't show like they do with water) and the joint may break if the pipe is subjected to bending/vibration, etc. Jim |

Also, flames and gas arent a real good combination either. Bubba |

NEVER allowed to be soft soldiered. There is a provision to allow for
brazing but you must use a special rod, which I have never been able to find in over 20 years. ONLY flare nuts with copper are allowed, compression isn't allowed either. You are sitting on a bomb just waiting to go off. Fossil fuel gas attacks copper and causes flaking which can cause a gas valve to stick open. Also, since it flakes it attacks the copper itself which means that it attacks the copper that was soldiered, which means the joint constanly get weaker by the second until the joint fails. With a flare it is less likely to have such a major leak since it is a mechanical joint, not dependant on a joint like being 'glued' together. Change it out, use Stainless steel. Better yet, since you dont know the codes I would stick to painting and call a plumber to put it in correctly |

Your local may or may not allow copper pipes; it depends on what additives
they put in the gas. Mine allows thick walled copper. No place allows soldering. Some locals allow only flare, some allow flare or compression. I don't know why; if solder is good enough for high pressure water it ought to work for low pressure gas, but maybe solder just isn't stable with gas. Check with your town; they don't have code requirements for fun. |

I've seen copper used for propane. But on NG systems, the furnaces I've
worked on have had aluminum tubing from the gas valve to the pilot. Speaking for myself, I prefer black iron. If you have black iron and copper in the cellar, it is very easy to tell w hich is the water, and which is the NG. -- Christopher A.

Many locations here in Georgia use copper for NG, use double flare fittings.
Mostly black pipe to a point then depending on device, Flex to furnace/water heater, Copper to fireplaces, outside grills, etc. I will be moving my outside grill soon, I will check to see what the inside of the copper looks like as I am curious to the issues with flaking I am hearing about copper and NG. Nayone have any links to sites that can expain all these issues ? Thanks, wrote in message ... Whats the point? If you got black pipe coming out the floor, all you need is a $10 gas flex pipe made for gas. You probably spent half that amount just on the copper pipe and all the soldering, etc. Now you are living in danger, because you were too cheap to spend $5 more to do it right. --- On 7 Jan 2005 14:43:01 -0800, "sawtooth" wrote: I have installed a Gas stove and had to run pipe to the kitchen.

Seemed pretty crazy to me, but he assured me it passed code in that area! Greg |

As soon as you turn it, the stem moves and it starts leaking. I guess they didnt know any better back then. Bubba |

Nothing like good old black pipe for gas! Greg |

What are the problems with soldering for gas pipes? Is this setup dangerous? Last time i checked only black threaded pipe can be used for inside gas lines.it will last forever. |
Brazing VS Soldering copper gas pipes
I am in Brazil now and here they use cooper pipe for gas lines in buildings, if to repair a leak, how to do a repair, i hearded you need to run nitrogen gas before solder or brazing because the gas fumes.

You run nitrogen to prevent the copper from oxidizing from the heat and forming crud inside the pipes. It's a much bigger problem when brazing because of the higher temps. |
