"I've got a buddy who can do the gas and the 'leccy. Super cheap."

[–] ghterve 42 points 2 hours ago* (last edited 2 hours ago)

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.

Time for a shower!

This happens when the neutral goes out in a house. Usually the waterlines will handle it, but if the house has pex the ground will go through the gas lines.

Especially if a high voltage line comes down on a gas meter for whatever reason.

Definitely run away and call professional… everyone i guess.

[–] David_Eight 1 points 15 minutes ago

I've never seen pex running into a house from the street/ground. It's always been copper up to the water meter at the very least and it's code (in NJ at least) to put grounding wire there.

[–] [email protected] 1 points 1 hour ago

This would have also been prevented if the electrical install included an RCD. It would have tripped instantly when the neutral gets disconnected

[–] AngryCommieKender 8 points 2 hours ago (2 children)

Would killing the main breaker at least prevent the heating of the pipes so that the expert isn't walking into a potentially dangerous situation?

[–] ghterve 9 points 2 hours ago

I think in this case the power heating the pipes is not coming from this house's electrical service, so killing the main breaker probably won't help.

[–] [email protected] 9 points 2 hours ago

I'm a little concerned killing the main breaker might result in a sudden temperature change that might fracture the gas line. Of course if you turn the gas off you might get fried.

"Home is equipped with a 50 Gallon gas water heater upgraded with RGB lines for an extra 10 FPS."

[–] [email protected] 13 points 3 hours ago

Looks like it can run doom

[–] [email protected] 12 points 2 hours ago (2 children)

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.

[–] [email protected] 1 points 17 minutes ago

Correct. Natural gas can't be over 15% to burn.

[–] ghterve 15 points 2 hours ago (1 children)

unless the gas pipe melted through

That looks pretty damn likely imminent to me...

[–] [email protected] 9 points 2 hours ago

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:

Normal person reading that: particle accelerator from TEMU

Me: oh god, there are TEMU particles??

[–] gedaliyah 16 points 3 hours ago

Hey, there's particles, they are accelerating. You got what you paid for.

This man exploded 3 seconds later, those are gas lines

I'm sure the water put it out.

Nice water-cooled setup!
Specs?

Nah.. everything is fine there, it's even glow to spice up your mood a little bit

What are those equipments?

[–] fouloleron 11 points 4 hours ago (4 children)

They look like a gas furnace and a hot water tank. My first thought was "Why are they connected? ", because I thought the tank had its own heating element. My second thought was "Aren't those water lines? How does a water line become incandescent?"

[–] [email protected] 11 points 3 hours ago (1 children)

The only way that immediately springs to mind is so unlikely to happen. It requires multiple faults/mistakes.

1: The chassis of one of the two units became live (connected to "hot" for you Americans) but was also not grounded in any way.
2: The chassis of the other WAS grounded and created a circuit for the current to flow.
3: There was no RCD (GFCD or whatever you guys call it) on the circuit.

In this way, that pipe would be the only thing connecting the two devices, and the resistance is causing a huge amount of heat (just like an incandescent bulb, or a heating element does by design).

Probably other possibilities, but it's just the first thing I could think of that could potentially produce this result. But, that's a lot of safety features to have either failed or just simply not been in place for this to be possible. So, frankly I hope I'm totally wrong.

[–] [email protected] 2 points 2 hours ago (1 children)

Even if that happened, wouldn't the pipe handle a lot more current than normal house wires, or even the main ones connecting the building to the grid. I assume the pipe would be thick enough that the wires in your walls would be glowing long before the pipe itself was.

[–] [email protected] 2 points 2 hours ago

I would have thought so, but I think it depends on how thin the skin of the pipe is. I would also have expected a breaker to trip under that much load. But, based on that happening, I'd not be surprised if there are bypasses and/or broken breakers.

When we moved into the house we're in now, the RCD (GFCI) didn't work at all. I pressed test, nothing. Had the electrician over to change it. He tested the actual actuation using earth leakage. Nothing. So, faults can happen too.

I want to be wrong, though. Because that's a pretty bad state to get into, I think.

[–] [email protected] 6 points 3 hours ago

Pretty sure its a natural gas powered water heater, so that would be the gas supply line. As to the incandesance, no clue.

[–] [email protected] 2 points 4 hours ago (1 children)

Maybe when it contains superheated steam?

[–] [email protected] 1 points 3 hours ago (1 children)

Some part of me believes that water cannot get so hot that it would cause metal to Glow.

I would be happy to be proven wrong.

I mean, unless you're saying that the pipe is heating the water inside of it? Which at that temperature that water would be expanding to over a thousand times its size and would probably blow that line to smithereens.

[–] [email protected] 6 points 3 hours ago* (last edited 3 hours ago) (1 children)

Steam has no limit to how hot it can get. Until it eventually transitions into plasma of course. By then the oxygen and hydrogen would have separated, I imagine. Then it's no longer water.

Superheated steam was a problem in some steam locomotives, as running the water level too low would allow the boiler to reach temperatures that would compromise the integrity of the metal.

Only liquid water has the boiling point as a "limit".

Apparently 3,000 C might be the limit, but idk.

I don't trust it entirely because it is a stack exchange website, there's not any hard evidence to back up the claim.

[–] [email protected] 1 points 2 hours ago

Yeah, don't know the specifics, but at some point the thermal energy will start knocking the molecules down into atoms.

[–] [email protected] 0 points 3 hours ago (1 children)

Both glowing portions are natural gas pipes. Perhaps it's somehow ignited inside the pipes and is super heating them but also somehow NOT travelling outside the two glowing sections and burning the house down???

[–] fouloleron 3 points 3 hours ago

I don't know, but I'd like to think I would shut everything off and run away until it demonstrably hadn't exploded rather than take a picture!
