Transit Tubes and Transit Crossings just randomly melting into 90*c Naptha?

[Alfons100]

My colony finally managed to get Plastic to make into luxury Transit tubes. I planned my base for that since the very beginning and I am mostly glad with the results.

Except due to the fact that, just randomly, my tubes for some unknown reason just melt into Naptha, and yes, I understand that plastic turn into naptha when it reaches 75*c, but my entire base is a solid 20*c. And yet for some reason, random parts of the tube network turns into naptha? That's 90*c as well. Usually it's the Crossings that turn suddenly melt down. Which is really weird.

Anyone know about this issue, is it a big, or a feature due to the tubes overheating, but my 150 hour experience has not seen anything about tubes randomly combusting.

probably some dupe carrying really hot stuff in tube(probably igneous rock which was magma)

or some refined metal from volcanoes

Could be the case. Because I just noticed that the transit tubes has a whole frigging 913 Thermal Conductivity, like, what? My colony recently got into managing things like schorching hot volcano materials. So yeah, when you say it that could be true.

Anyone else find it odd that plastic melts at such a low temp?  

Plastic is actually made from naptha, not the other way around (I'm no chemical engineer though).

Either way it seems strange that boiling a bowl of water in the microwave should result in a pool of naptha...

most common thermoplastics melt between 80C and 160C (with 120C being typical for HDPE)

Most engineering plastics like nylon or polycarb can go as high as 300C

I hope we get a chemistry update someday were we can construct most polymers from plastic that can endure hotter temps

Maybe a 'sci-fi' material that is called Plasteel that so many sci-fi scenarios have now. Where you can mix some sort of steel with plastic for a refined metal with antiseptic properties.

Why stop there? how about Mithril or Orichalum?

My understanding of those minerals is that they are naturally occurring, rather than fabricated/refined from other materials.  We'd need a new biome or 2 for that, would we not?

I feel like we are ready for a new biome to be added

[PhailRaptor]

Agreed, but that would be, at minimum, after Ranch Mk2.

yep, I'm not expecting any time soon, but then again sometimes Klei introduce new features before their time

*cough steam turbine cough*

Not me, this would validate all those nights my brother stayed home studying on his way to a ChemE degree, while I drank my way to a Psychology degree.

Another bit of weird Naptha - I had some randomly appear in a water tank for a steam geyser. There is nothing plastic there, however I did build a steam turbine there. The steam cave is enclosed and out of the way, and there is nothing else made of plastic in the base aside from some beds, miles away. How did the naptha get there?

The only thing that my incredible Sherlock Holmes skills can deduce, is that maybe during construction of the turbine, a dupe was carrying plastic to the construction site, and then the day ended - so it dropped the plastic into the water.

But then if that's true, the water shouldn't be hot enough to melt the plastic - it's only like 50 degrees or something (condensed steam). 

Get to it master sleuths!

Considering that we get plastic straight from crude oil then zap it into places, this might be styrene plastic we're working here.  They can warp in 50 C water or melt over a candle flame.

mind you thats inside the fire and thermal transfer probably drives it down by a factor of 10 every few centimeters

[PhailRaptor]

What's the primary element of the Steam Turbine?  I know it costs both Metal and Plastic to make, but which is the primary?

If it's the Plastic, then it could be melting.

 It's happen for me sometimes with no reason, liquid frozen in my pipe for no reason (water is at 20 °C before and after) but frozen, it's most of the time the same pipe that broken, so i think probably it's a bug or i use too cold material to build the pipe

I found a rather specific issue: If my water pipe passed directly under an algae deoxydizer, and the oxydizer was producing oxygen while the water flowed, then suddenly the temperature inside the pipe would drop to absolute zero for that tick.  Which, of course, would drop the water to below freezing and break the pipe.  If the water wasn't flowing at the time, OR the oxydizer wasn't pumping out oxygen at the time, then nothing out of the ordinary would happen.

I read this to study up on Transit Tubes and I find out they melt. "Lucky" Me
