Brazing VS Soldering copper gas pipes

sawtooth · 2005-01-07T22:43:01+00:00

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 toBlack pipe which is what comes out of the floor in the Kitchen for theGas Stove to hookup to.The copper fittings that I put in were soldered using standard plumbingsolder.There have been no leaks and this has been in place a couple of monthsnow, but I've read somewhere that soldering is only for water and notgas.What are the problems with soldering for gas pipes? Is this setupdangerous?

Pretty freaky! Even using SST makes me a bit nervous! Nothing like good old black pipe for gas! Greg

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.

Don't know about Brazil but soldering gas line in Canada is forbidden. Must be brazed. Same with refrigreration lines. You DEFINITELY want the lines purged - well purged - before applying a flame!!
