At an inspection the other day, ns noticed a galvanized elbow installed in between 2 straight runs of black color iron gas pipe. Is galvanized permitted as a general rule? go it count on neighborhood codes?


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

You are watching: Can galvanized pipe be used for natural gas

If drip/dirt foot are present the hazard is low however I would keep in mind the non conventional use that the galvanized installation in the gas piping system.


Well for when we agree Micheal. Ns would keep in mind it, it must be adjusted . The does depend on to be you are the execute not also ask because that drip legs below .


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

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

It varies at whereby you live.

From Ameren Illinois, my local utility provider:

Fuel Line:Customer Requirements:

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

…… **The customer fuel line from the meter throughthe house wall **must it is in a minimum the one (1) inchIPS schedule 40 black color iron pipe. because that CorrugatedStainless steel Tubing (CSST) installations, atermination fitting an installed on the external housewall is acceptable for the change from blackiron pipe.

I stated IRC. Regional codes vary.


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

ASME B 36.10, 10M;ASTM A 53/A 53M; orASTM A 106.Commentary: stole pipe have to be Schedule 40 or heavier, need to complywith one of the noted standards and can it is in blackiron or galvanized. Contradictory to popular belief, naturalgas does not adversely react through the zinc coating ongalvanized pipe."

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


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

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

Not certain if that still is with every one of the fuel line. It used to be, at the very least by neighborhood AHJ.

But I believe the fuel mixture has actually changed, for this reason maybe have actually the restrictions.

I seldom see galvanized top top fuel lines, uneven it’s a nipple, elbow, etc.


As Joe Funderburk discussed (which is the same necessity as 2013 California plumbing Code, Fuel Gas Piping 1208.5.2.2), galvanized pipe might be supplied for herbal gas piping.

2009 IRC G2414.4.2 (403.4.2) Steel. Steel and wrought-iron pipe shallbe at least of standard 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 Hot-Dipped, Zinc-Coated, Welded andSeamless”, ar 17, discusses Galvanized pipeline requirements:

Galvanized Pipe17.1 Galvanized pipeline ordered under this specification shallbe coated v zinc inside and outside through the hot-dip process.The zinc used for the coating candlestick be any kind of grade the zincconforming to Specification B6. …

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

There is a plastic coated pipe because that underground (not CCST, a black pipe v a yellow coating) or nowadays they usage all plastic line, however it has to be plastic welded by a certified welder, not a residence handyman job.
