For things that are "hmmm".
Rule 1: All post titles except for meta posts should be just plain "hmmm" and nothing else, no emotes, no capitalisation, no extending it to "hmmmm" etc.

This makes total sense but how does this not go boom? No oxygen in the gas line?
Exactly that.
So you're saying you should poke a hole in the line?
That would just make a jet fire. Which may eventually result in the catastrophic failure of the pipe but if you really want to see a house jump cut a slot. Much more area for gases to mix. It's only 1psi probably so a hole may not be enough.
Autoignition temperature of natural gas is above 500c. Need a spark, or enough heat, there could even be a leak and this not be enough heat to ignite.
I’m pretty sure if it’s red hot it’s close to if not over 500°C but I guess it depends on the metal.
At least according to this Wikipedia article. https://en.wikipedia.org/wiki/Red_heat
So when you say "Autoignition", then ignition of what? For natural gas to "ignite", as in burn or in other words oxidize, there need to be an oxidizer present.
