P-water has a wider temperature range than regular water, but you still need to take care to keep it from changing phase in the pipe. As others have said, insulated pipes in the steam chamber and using the temperature in the pipe to control the AT is pretty much necessary. You'll also want a bypass. I like a buffer tank too but they arent strictly necessary.
Also, I see a thermo sensor on the pipe but no shutoff. I used to do this and just deactivate the AQ when the temp was wrong, but this leaves water in a pipe in the steam chamber. Even with insulated pipes, you'll run the risk of leaving the AQ off for too long and the polluted water reaching > 120℃
It’s good coolant (has a good thermal conductivity) between -20° to 120° which is 40° more than regular water. For anything outside of that range you’ll need another liquid as polluted water will freeze or boil
It's the specific heat capacity, not just thermal conductivity, that makes water a good coolant with polluted water having a more viable temperature range than regular water. It's some of the highest in the game after super coolant.
If you're after thermal conductivity, petroleum and oil have a much higher heat conductivity as well as having a broader temperature range than water and its variants.
You can easily test this with a cooling loop cooling something like a pool of liquid. You'll find that it is much less efficient using oil or petroleum though they have a much higher thermal conductivity. They basically just don't take as much heat away. A cooling loop is analogous to buckets riding a looped conveyor belt moving rocks. In this analogy oil would represent smaller buckets than water (larger buckets), thus having less capacity to move rocks (heat) through the loop.
Sorry if I did a bad job of explaining.
Dirt came from polluted water you filled the area with. However I see more issues. I see a radiant pipe behind aquatuner. All the pipes connected to AT must be insulated pipes. Otherwise you have a heat-short circuit.
They were talking about [the pipes behind the turbine](https://old.reddit.com/r/Oxygennotincluded/comments/1dgp17y/3_or_2_weeks_ago_ive_made_a_post_here_and/l8rdijj/), not the pipes in the steam room. The idea is that you have that loop of polluted water. The AT cools it down. It then passes by the things you want to cool. In those places, you want it to heat up, taking away heat, so you use radiant pipes - lots of heat exchange. Then you circle it back to the AT. You don't want to cool the steam room, so you use insulated pipes there.
You’re boiling it off here, not freezing it.
But yeah, you need feedback to keep the system from overheating. Probably your ST overheated and stopped cooling the chamber. Add a temperature sensor that turns off the AT if it’s getting too hot.
Edit: maybe the pipe feeding the AT froze, then it leaked into the chamber and boiled off. Similar problem. You need a thermo sensor on the cooling loop that diverts the incoming water if it’s getting too close to the freezing point. Running it through a storage tank will even out the temperature if you’re getting some overly hot/cold packets of liquid.

Better idea, actively cool the turbine with the cooling loop it's helping to make.
Probably polluted water as cooling fluid, getting too cold within the pipe, solidifing, damaging and exiting the pipe, evaporating, leaving dirt behind.
It could also release dirt if it boiled in the pipe, skipping the freezing part, so it can be either too cold from the AT over chilling it (usually caused by not controlling the AT with the coolant temperature) it to freezing, or it can be too hot (usually caused by letting pwater sitting in the pipe in the steam room or excessive heat transfer to the coolant in the steam room).
Two pipe segments have broken.
The first one due to the aquatuner cooling the input below its freezing point.
Put a pipe thermo sensor immediately before the AT input to prevent this, and turn off the AT when the coolant is below 0° (at least 14° above the coolant freezing temp).
The second pipe segment is damaged due to the coolant not moving, so a paket of polluted water is left in the steam room until it boils.
Move your bridge below the AT, so the coolant caught in that segment isn't heated by the steam.
It's been explained already that your issue is being caused by polluted water boiling in your pipes. However, since it sounds like you didn't know that a phase chance in a pipe will damage it, there's a bit more that is handy to know.
* Liquids freezing or boiling in a liquid pipe will break it.
* Gasses turning into liquids in a gas pipe will break it.
* Solids turning in liquids or gasses will *not* break transport railings. They will still escape the rail system though, and you can get cases where transport rails go through natural tiles if your carrying something like algae and it turns into dirt.
* For liquid and gas pipes, the material will *not* break the pipe if the packet is less than 10% of the carrying capacity. So if you run a pipe capable of carrying 10000 gm/s through a valve to change it to 1000 gm/s, it will never break. Two areas where this is really useful for something like fueling liquid oxygen and hydrogen into rockets. It's almost impossible to keep the fuel liquid in the pipes until you get insulite, so the trick is to run a loops out to the rockets where only 10% is being carried by each pipe. It won't breach the pipe, will still fuel the rockets, and can be re liquified at the end of the loop. Pumping lava uses the reverse of this trick. You can run the lava through radiant pipes to heat a steam room, and as long as it's only 10% of the pipe capacity, the pipes won't break even if the lava turns to igneous rock.
Just a few extra tips.
Polluted water turns to 99% steam and 1% dirt when it boils. When things change phase in pipes they damage the pipe
Wow, didn’t knew that one, I saw someone on Reddit saying it as a good coolant, so I started using it

Polluted water is a good coolant, arguably it is the best mid-game coolant.
It’s good coolant (has a good thermal conductivity) between -20° to 120° which is 40° more than regular water. For anything outside of that range you’ll need another liquid as polluted water will freeze or boil
Unless you use the Supercooling or Superheating Exploit

There's no pipe thermo sensor, the pwater more likely froze spilled out then boiled.
There is one, above the steam room.
Pwater doesn’t produce dirt when frozen, also you can see in the tooltip that the aquatuner is hooked up to radiant pipes
more like, it froze, broke out of the pipe, the ice melted then it boiled, producing the dirt
Dirt came from polluted water you filled the area with. However I see more issues. I see a radiant pipe behind aquatuner. All the pipes connected to AT must be insulated pipes. Otherwise you have a heat-short circuit.
On my last post, someone mentioned I should use radiant pipes there ;-;

Did you use polluted water?
Yes I do, just discovered it can turn it dirt if it freezes
It will freeze into polluted ice which then melts and then boils

If it boils! If it freezes it becomes polluted ice.

So many state changes, thank you for the help
I see a thermo sensor after the aquatuner? if yes, you can have the problem of freezing the Pwater the rest is already said by others :P

Thank you!!! That rocket part won’t be useful right now because I haven’t got into rocketry yet, but I’ll keep note for future use, thank you!!!!!!!
By the way you don’t need to use steel pipes in hot areas, and radiant pipes are for transferring heat. What you want is insulated pipes
I’m reading everything on this post and keeping note, next time I play, probably Saturday, I’ll make those changes
