I think the concern here is when repairing damage or adding a runout, a torch would be necessary on a line that has gas in it. Recipe for disaster to the untrained person
Gas lines in residential neighborhoods around me are like 10psi or less.

seismic zone, building may move and then eventually put tension onto pipes... just my though. Usually we do not soft solder gas pipes because if there is a fire... much longer time to go until brazed lines leak

That would be my thought.
For instance, the reason you can use a street 90 in gas, has to do with it not having a high enough tensil strength.
I’ve heard in California, all appliances shall have a piece of flex on it for this reason.

Do I have this right? You can't use a street el on gas? Are you talking about black pipe els? On the copper I always thought solder had more to do with a house fire. I have never understood running copper for gas lines. Every time I have dismantled a copper gas line I can shake out loads of this loose stuff in the lines that look like graphite flake.

5.14 international fuel gas code.
No shoulderless nipples, street fittings in black iron.
Hanging out with the mice behind the fridge talking bad about the roaches in the oven.

In gas.
Hydronic piping is fine.
What is a shoulderless nipple or a shouldered nipple for that matter?

I'm tired of these mediocre "semi flammable" refrigerants. If we're going to do it let's do it right.
Unless we change direction we are likely to end up where we are going.

Joe munde, Steve Osage, Gary berling in Cincy would hit you on them every time.
Reggie, use to pass out stickers for guys to put on furnaces.
The two dayton inspectors are let’s say……
Ted who does the commercial inspections is a bit better at actually spotting violations.
I went through a whole back and forth with dayton over spray foam insulation for ductwork in attic. Inspector came out and didn’t even mention it….
County is hit or miss, depends on the day of the week…..
Wow! In 45 years I must have a few thousand violations when you factor in close nipples. Thinking about it I can see that the pipe wall thickness is pretty thin.

Between close nipples and street 90s I am toast.

I’m not absolutely sure about this, but:
I believe that left/right nipples in gas are also banned.
A left right is a nipple that with you spin clockwise, it tightens in both directions.
One side of the threads is actually in reverse.
A special left right coupler is needed with it.
It’s purpose is so that you can cut out a section of pipe, and not have to use a union.
As far as street 90, there are applications in gas that supersede IFGC.
Goodman GMH is a specific example. The installation manual said for right entry, to use a street 90, a 3in long nipple, and a 90.

Also any reducing bushing less than a 2 size difference shall be steel, not black iron.
Ie. 1/2" to 1/4" is ok as black iron. 1"2" to 3/8" cannot be black iron...must be steel.

my uncle was remolding his kitchen , he needed to move the water heater temporarily, he used sch 40 PVC for the natural gas line. the inspector didn't like that, and sent the local gas company over to red tag the house, until he replaced it with black pipe.
