When do pipes break from external temperature?

[Nurgus]

So ive got igneous rock insulated pipes going from the AT to the steam turbine cooling basin. The water never flowed. The temperature in the AT-Basin is around 138°. the Pipes are broken but there is no polluted water in my clean water steam... take a look :

Edit: i just noticed the outtake of the steam turbine was connected to the aquatuner cycle... still the water never moved inside ( the steam turbine goes active at 200°C)

Liquid in the pipes froze.

if it was an external temperature that exceeded the pipe material melting point then the pipes would probably deconstruct completely.

[Nurgus]

well if water freezes in a cycle it usually drips, right ? the temperature of the water is around 50°C and the AT never went active yet

i have to open the chamber anyway because i forgot to build a second outtake for the Turbine...

Edit: Maybe the water inside started to boil? but how did it get back to 50°C then. confuzzling

No idea, need to see pipe layout. Use pipe thermo sensor+shutoff valve and manage your liquid temperature, "before" it enters the Aquatuner hot area.

E.g if using water(not a good idea since it has a small range), freeze point is -0.65 , so 14-0.65+2(extra temp buffer due to environment heat exchange, for my case ceramic insulated pipe) = 15.5 C. Any water that's colder will not be piped to the aquatuner. Beyond this automated shutoff, you can use the sensor numbers to see if the water is somehow too hot that 1 or 2 degrees of environment heat exchange boils the water or you allow that water to hang around in the hotzone for too long and it boils eventually...

Also polluted water becomes pure water when vaporized. Losing the polluted part forever...

My guess would be that the water boiled and turned to steam because the AT wasn't running.

If it's sitting in a very hot pipe for a while that pipe will need to be made of a better insulating material than igneous rock.

actually that makes more sense, the pipes inside the aquatuner chamber should be made of insulated ceramic or insulated insulation.

pipes getting damage if designated for these pipes fluid changing its state.
i.e. :
if water in water pipe
freezes: pipe receiving cold damage
evaporizes: pipe receiving hot damage

also, you need to use insulated ceramic pipes atleast

yes i usually use petroleum for the ATs but at the point i build these it was not available. with petroleum i dont have to change the setup at all right ?. i guess it were boiling. i still wonder why it then cooled down to 50 again :) so yeah not allowing water in the chamber before it is needed is another idea but i expected the insulated pipes to be more insulating :) another lesson learned. thank you for time guys!

Edit : i dont have any clay yet :P

That's a mistake. Petroleum has way lower heat capacity, meaning you'll pay about 2.3 times as much power for the same cooling.

If you have polluted water in insulated pipes all you need is for the aquatuners to either be on at the same time or be off. If the steam temperature is 125 or lower when the pipe is still it will take an eternity for the pwater to boil if it ever will.

If you mixed in regular water from the steam turbine that could be what damaged the pipes. Small packets of 95° regular water can quite easily vaporize in the pipes.

i changed the system like this now :

theres no more water left in the chamber. i thougt petroleum was a good thing to cool stuff. guess i have to understand heat capacity and the like

opening the chamber will be a pain... maybe tempshift plates will help cool the steam down fast enough

The goal is not to have water in the aquatuner chamber, you want it all to be steam, and the faster the steam heats the more power the steam turbine generates.

Also, a little factoid: building tempshift plate adjacent to a solid tile will cause heat to be pushed into the solid tile at a faster rate, so the last thing you want to do is build tempshift plates adjacent to insulation tiles because it will render them ineffective.. heat will be transferred into them much faster and then that heat will bleed out the other side.

Just build a liquid lock with oil right next to it and chamber will be accessible without anything leaking in/out.
Also petroleum, oil and ethanol have their uses in cooling, especially before you have supercoolant, you have to use it wisely though, as you loose a lot of efficiency compared to water because of how aquatuner works, if you use it with aquatuner.

thank you for your hints but not spoiling it :) since i didnt got the idea before with the already known but not used waterlock ill keep going the road a chose now... :) didnt drip too much. prolly shouldve used exosuits aswell but hey, what else did a build a hospital for eh :D
i like to learn from my own mistakes
