At an inspection the other day, i noticed a galvanized elbow installed between 2 directly runs of black iron gas pipe. Is galvanized enabled as a general rule? walk it rely on local codes?


The problem with gavanized pipeline is the possibility of the coating flaking and then plugging valves and also orifices.

You are watching: Can you use galvanized pipe for gas line

If drip/dirt legs are existing the danger is low yet I would note the non conventional use the the galvanized fitting in the gas piping system.


Well for once we agree Micheal. Ns would keep in mind it, it need to be changed . It does count on to be you are the perform not even ask because that drip legs here .


I was told not permitted here yet if to run underground to say a garage would you fairly use black color or Galv ?

I said IRC. Neighborhood codes vary.


2009 IRC G2414.4.2 (403.4.2) Steel. Steel and wrought-iron pipeline shallbe at least of traditional weight (Schedule 40) and also shall complywith one of the following:

You likewise said this

“It’s a misconception that galvanized is prohibition for organic gas.”

Is galvanized prohibited all over else by her utility? Or just the fuel line?


Is galvanized prohibited anywhere else by your utility? Or simply the fuel line?

It’s not prohibited with water lines, if that’s what girlfriend mean.

Not certain if that still is with all of the fuel line. It supplied to be, at least by regional AHJ.

But I think the fuel mixture has actually changed, therefore maybe have the restrictions.

I hardly ever see galvanized ~ above fuel lines, unless it’s a nipple, elbow, etc.


As Joe Funderburk stated (which is the same need as 2013 California pipes Code, Fuel Gas Piping 1208.5.2.2), galvanized pipe might be used for organic gas piping.

2009 IRC G2414.4.2 (403.4.2) Steel. Steel and wrought-iron pipe shallbe at least of conventional weight (Schedule 40) and shall complywith among the following: 1. ASME B 36.10, 10M;2. ASTM A 53/A 53M; or3. ASTM A 106.ASTM A53 specification. “Standard Specification forPipe, Steel, Black and also Hot-Dipped, Zinc-Coated, Welded andSeamless”, section 17, discusses Galvanized pipeline requirements:

Galvanized Pipe17.1 Galvanized pipe ordered under this specification shallbe coated through zinc inside and also outside through the hot-dip process.The zinc supplied for the coating shall be any type of grade that zincconforming to Specification B6. …

I to be told not enabled here but if to run underground to say a garage would you quite use black color or Galv ?

There is a plastic coated pipe for underground (not CCST, a black color pipe v a yellow coating) or recently they usage all plastic line, yet it needs to be plastic welded through a certified welder, no a residence handyman job.

I thought that the whole attend to black stole was the they were seamless whereas galvanized have actually seams.
