What pipes to use for liquid glass? [solved]


Recommended Posts

Seems like an easy question, but since Abyssalite is not available anymore, I always get "Cold Damage", and while the pipe heats up, it is down to a low temperature after repair again. Do I just have to repair and repair again until I get the new super-insulators?

This is happening because the Glass is transforming from a liquid to a solid inside the pipe.  You need to use a stronger insulator for the pipes, which should also be Insulated Pipes.  So you will probably want to build the Insulated Pipes out of Ceramic, at least until you have reached Space Age materials through the Molecular Forge, where you can make the new industrial insulator material (what's it called, exactly?) from Abyssalite and materials collected from other planetoids.

You can also build the Insulated Pipes inside Insulated Tiles.  This will further slow down the rate of heat transfer.

Sorry, in particular isolated ceramic pipes do _not_ work. That was the first thing I tried before asking here. Putting an insulated tile over the place were the breakage does happen is also impossible as that is still in the glass-forge building area

Can you post a screenshot of your setup? Insulated ceramic has been working fine for glass on the test branch for me.

If you can't build insulated pipes behind an insulated tile because of space constraints, you should re-think your design.

Also, set up your system so that the hot liquid doesn't stand idle in those pipes, ever. You don't want to allow time for heat to transfer out. Molten glass in the pipe should move continuously towards its destination with no delays.

Also, try and make said pipe fairly short to limit the time the glass will lose heat.

That too.

Well, here is the design. Does not get any simpler. I am beginning to suspect I trigger some bug here, maybe because it is in space.

The glass forge is ceramic, the pipe is isolated ceramic and the pipe that breaks is the one directly behind the glass forge.

Welp.
I'm stumped :p

Looks like a bug to me.

The problem is likely a combination of the tile directly below the red "No Fabrications Queued" symbol not being insulated ceramic and the puddle of liquid above that tile. Mostly the liquid though. Molten glass stored in the forge acts as if it's in the tile with the power input. So it transfers heat very well with any liquid in that tile and somewhat well with the solid tile below. This has probably caused the molten glass in the forge to become supercooled below it's freezing point. As soon as it enters a pipe, that section of pipe breaks regardless of what it's made out of.

Try cooling the forge with gas instead of liquid, gas should suck heat out of the molten glass less quickly while still cooling the forge. Alternately you can replace that middle tile with a mesh tile with one empty tile below the mesh, this should prevent any liquid sitting there sucking heat out of the glass. Liquid to either side of the mesh will cool the forge.

Ok i know exactly what is happening here. It`s not the pipe. it could be insulated abyssalite and it would still break. Why? Beacause the water on the ground interacts with the glass forge interior (for some reason) and cools down the glass before it even reaches the pipe. You`ll get dupes scalding, a lot of steam and breaking pipes unless you get rid of the water from the ground. There can`t be any liquid under the forge or it breaks. You might have to deconstruct the forge and rebuild it as well possibly.

Thanks, that the glass gets cooled in the forge was the problem. I did not suspect that at all.

As this is in space, I placed the forge into 100kg/tile of pwater for cooling and that also cools the glass in the forge as well. Remove the water and it works, except that then the forge overheats after a while. 

I will just have to find some other way to cool it, probably will have to move it out of space for that.

Yes, figured that out as well now. I will actually have to remove the forge from space as it cannot really be cooled there, it seems.

It's not the forge cooling (read what people said).  As far as I understand - the problem is that things inside machines interact with the environment as if they were sitting on the ground.  If the ground tile they interact with is not insulated, the contents will transfer heat - in his case, the tile further transferred to the poluted water, so the glass inside the forge was cooling down too quickly.

EDIT: Oh and BTW, building contents don't t transfer heat (or transfer it very slowly) with the building itself so the temperature of the Glass forge itself is irrelevant.

Mop the floor, dump the glass into a dedicated cooling pond a few segments away instead of on the floor, keep the glass forge cool with gas around it instead of making cooling difficult in a vacuum?  This build doesn't need to be complex.

depends have you looked at the stats on obsidian as a building material lately ? silly high melting point decent thermal rates. wana use liquid glass as a heat source for steam? obsidian. wana build a a furnace that can handle molten lava obsidian .
