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


The worry with gavanized pipe is the opportunity of the coating flaking and also then plugging valves and orifices.

You are watching: Can you use galvanized pipe for gas

If drip/dirt foot are existing the risk is low but I would keep in mind the non traditional use the the galvanized fitting in the gas piping system.


Well for once we agree Micheal. I would keep in mind it, it need to be changed . That does depend on to be you are the carry out not even ask for drip legs below .


I was told not enabled here yet if to run underground come say a garage would certainly you rather use black or Galv ?

And the IRC. The a misconception the galvanized is prohibited for organic gas.

It varies at where you live.

From Ameren Illinois, my local utility provider:

Fuel Line:Customer Requirements:

…… The customer’s fuel line is the pipe that connectsto the outlet that the gas meter set and extendsthrough the wall surface into the house. The fuel lineshould go into the house or framework within three(3) feet the the gas meter set.

…… **The client fuel line from the meter throughthe house wall surface **must be a minimum of one (1) inchIPS schedule 40 black iron pipe. because that CorrugatedStainless stole Tubing (CSST) installations, atermination fitting placed on the external housewall is acceptable for the transition from blackiron pipe.

I said IRC. Neighborhood codes vary.


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

ASME B 36.10, 10M;ASTM A 53/A 53M; orASTM A 106.Commentary: steel pipe should be Schedule 40 or heavier, need to complywith one of the detailed standards and can be blackiron or galvanized. Contrary to popular belief, naturalgas does no adversely react through the zinc coating ongalvanized pipe."

You additionally said this

“It’s a misconception the galvanized is prohibited for natural gas.”

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


Is galvanized prohibited almost everywhere else by her utility? Or just the fuel line?

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

Not sure if the still is with all of the fuel line. It offered to be, at least by neighborhood AHJ.

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

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


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

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

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

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

There is a plastic coated pipe for underground (not CCST, a black pipe through a yellow coating) or recently they use all plastic line, however it has to be plastic welded by a certified welder, not a house handyman job.

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