Hell yeah well again im sorry bout that =)!
This is so damn awesome!!! What is a laminating pouch?
A long time ago copper was used for gas but thats not the case anymore. Just like galvanized pipe isnt used for water lines anymore copper is no longer used for gas. =)
It does actually, i guess i should have asked what type of gas you were running through it first. LPG is ok as long as you used ACR type L copper. =)
There are small amounts of sulfur in natural gas, when natural gas runs through copper it creates copper sulfide crystalline in the pipe. this leads to build up of the copper sulfide, clogs, weakened pipe, and eventually ruptured lines. I dont think i need to explain what can happen when you have a ruptured gas line. Im not trying to convince the author to pull out their line, im just pitting the info out there.
As a plumber who works daily with running gas lines i gotta say copper should absolutely never be used for gas, your pipes will corrode and eventually leak especially because theyre underground. Awesome instructable though, i suggest buying polypipe in place of the copper you used.
