I have no idea what to do if I see this
Go to the breaker box and pull the big one labeled "main". Then call the fire department.
Get the fuck out and call the fire department.
Leave immediately and call 911 for an impending gas explosion. Tell them exactly what you saw, it will need to be disconnected somewhere very far away from the house. Aside from this being an obvious fake if you see a glowing pipe it’s the result of a deadly serious electrical fault that has bypassed at least 2 safety mechanisms that would otherwise prevent this catastrophic failure and at that point you really don’t even want to be touching the walls of the structure involved.
Someone linked a story that didn't have an image (didn't watch the video) so this may not actually be fake
Run. That's what I would do. Then probably call the fire department, the gas company, or an exorcist. Possibly all 3.
Either turn off the gas if you can safely do it, or call your gas company so they can shut off the supply to your house.
So there's an air leak upstream allowing a fire inside the gas line. And the house didn't go up in flames I assume. Probably this situation would not end in a big explosion but rather just a house fire. Still pretty scary.
Showed my partner, they said, "Is this some kind of raaave??"
"I've got a buddy who can do the gas and the 'leccy. Super cheap."
Time for a shower!
Pumpkin-spice gas for the holidays
When this was posted on Reddit recently, someone claimed this was caused by a fallen power line that made contact with a gas line. So, power flowing into the house through gas pipe and back out through equipment grounds, heating up lower resistance gas pipes in the process.
Photo reportedly taken by fire fighters or gas company employees.
Edit: I meant to type higher resistance...
ELI5 anyone?
This makes no sense at all.
Why would only these two specific pipes get hot, so hot to glow, but not the other lines connected to it? And not the fittings around it? It's all copper, so even if the power itself doesn't heat them up, why would being connected to an extremely hot pipe heat it up. Since it's you know copper and being good at transferring heat is what it's known for.
And why would the lower resistance part be the part that get hottest? Low resistance means less loss, so those parts would in fact be the coldest of all.
Plus thin walled copper pipes can't get so hot they glow without melting or at the very least lose all structural integrity and break.
And a downed power line with a short to ground would almost immediately turn off. It's when there isn't a direct line to ground those things are dangerous. As soon as it shorts, it gets turned off at the source to prevent further damage, fire and not cause issues upstream.
Either it's Photoshop or someone has wrapped led lighting around some pipes.
Holy shit that must be some freak combination of factors. Thanks for sharing!
Both of the lines that are lit up are flexible aluminum couplings. They're required in some areas as the final connections to the appliances. They're in line with cast iron gas pipe and fittings. They are much more thin and way better at conducting heat.

Thanks for the clarification, pipes look like copper but might be cast iron.
Still doesn't fit with the explanation, aluminum has more resistance than copper, but not that much more. The resistance of cast iron is an order of magnitude higher than aluminum. So it would still be the lowest resistance in the circuit and thus the coolest part.
And cast iron is pretty good at conducting heat. Not as good as copper or aluminum, but still pretty good. We've been using the material to make pans and pots for cooking because of it's thermal properties. So the heat wouldn't just stop at the fitting, but continue on at least some ways.
Moreover it's physically impossible to get aluminum hot enough to glow like this and still keep its shape. It melts at 600 degrees C, well below the point where something gets red hot, let alone yellow like this. If the aluminum were to be this hot, it would be in a puddle and at risk of burning.
The flexible pipes are normally stainless steel. The main gas line is steel with thick walls so this seems plausible to me. Stainless steel has higher resistance than steel and is so much thinner.
Sorry, I meant to type higher resistance. On my water heater, the equivalent part that is glowing in the picture is a really thin flexible corrugated gas pipe that surely can carry much much less current than the iron gas pipe feeding it before it went really high resistance. I could totally see it glowing like this with enough current. But if it is aluminum (not sure if it is), what you said makes sense.
My gas pipe to the house comes out of the ground inside a plastic protective pipe sleeve, so I can imagine it possibly not having enough of a low resistance path to earth to trip one of the cutout fuses on the primary distribution line. Granted, mine also has a big ground wire bonding it to the house ground, which I would think would help here...
/shrug I was just sharing what I read. It was supposedly the explanation as to why local breakers on the house didn't trip.
Well that's truly fucking terrifying
While it looks scary as fuck, wouldn't it not actually explode unless the gas pipe melted through? There's no oxygen in the fuel, so it can't combust. I guess as the gas heats up, it's also possible the for the tank or lines to spring a leak.
Either way, I'd be nopeing out and calling emergency services.
Correct. Natural gas can't be over 15% to burn.
unless the gas pipe melted through
That looks pretty damn likely imminent to me...
I think you're right. I was curious, so I looked it up.
The melting point of copper is 1,085°C, and judging from this chart, its definitely getting close:
You ever see gas hookups in the US?
We use black pipe for most of the run. Cast Iron. The actual hookup itself is a flexible pipe...SS or Aluminum I think. Been a long time since I had gas. Sometimes they have like a rubbery-epoxy-ish coating but I assume that's now quite gone and stinky.
Def not cast iron, cast iron is used for waste pipes and it's brittle you could never get threads on cast iron. It's actually steel even if we call it black iron. A lot of newer houses will run solid pipe from the main to a central location and build a manifold with corrugated steal (flexible pipes) run to the terminal points.
Oh, huh. That's interesting. I'm from the great white north, and our gas hookups are copper from what I've seen. If this is indeed iron, then the melting point would be higher: ~ 1,540°C.
Interestingly that colour temperature chart is supposedly fairly consistent across different metals.
Tbh I don't know why we don't use copper. I imagine because it's more difficult to fuck up threaded and doped connections as opposed to soldered ones.
