glass forge pipe breaking

[Craigjw]

I thought I knew how to make a glass forge work, but it seems that I'm unable to.  There is nothing on the floor below it, only insulated igneous tiles.  The room is in hydrogen at 50c.  I've tried varying levels of Hydrogen to no avail.

Do I need to use a different gas?  I've tried a vacuum, but there's no way to cool it down.  Perhaps metal tiles below it and cool them, while maintaining a vacuum?

Strange i never ever have problems with it i just make the pipes of insulated obsidian and never ever have water in the "feet" of the glass forge itself " when i had water or any other liquid it breaked non stop too".

[Craigjw]

I'm using ceramic pipes.

[KittenIsAGeek]

The pipes aren't breaking because of the heat.  They're breaking because the glass is cooling down to a solid before it reaches the end of the pipe.  

[Craigjw]

The pipe is breaking at the exit of the machine, on the first pipe, the glass hasn't travelled.  The rest of the pipes are fine and aren't breaking.

[Neotuck]

Where's the glass going?  I don't see a pipe vent in the picture

[Craigjw]

down and then left when it reaches the floor tile.  I thought I'd try cooling the floor, please ignore the extra pipes.  The glass pipes haven't changed.

Turns out, cooling the floor isn't working either, the floor doesn't cool the machine, that breaks now instead of the pipe.

[Neotuck]

I always drop a little liquid on the floor of the machine.  Also I let the glass drop on the floor next to the forge so the pipes never break.

This might seem like it would generate a lot of heat but it doesn't in the long run.  The need for glass is limited and wheezies can cool the machine during the down time

For me is the total oposite i can build it anywhere no infra needed just never ever let water be in its feet and use obsidian insulated pipes only " ceramic also breaks from time to time for some reason".

A couple of weezes should be enough, the machine only produces 16 KDTU's, doesn't a weeze remove 12 KDTU's, or am I confusing it by a factor of 1000, ie 12 DTU's, not KDTU's.

I'm wondering if Hydrogen is too thermally conductive.  I'll try O2 and report back.

An atmosphere of O2 at 650g's seems to be working ok. 

Can someone please confirm that a Weeze removes 12 KDTU's please, and not just 12 DTU's.

I confirm that in hydrogen of enough pressure to guarantee full 1kg packets through the wheezewort, it deletes 12kDTU of heat. (5 degrees per packet * 1,000g per packet * Hydrogen's 2.4 specific heat attribute) 

In oxygen or lower pressure hydrogen, it's less. 

[Craigjw]

Thanks.  I'll see how 2 fair's out and add a 3rd if necessary.

Wheezworts do 12 KDTUs in Hydrogen of 2.2kg/tile.  I believe the pipes even though ceramic were transferring heat with the hydrogen and cooling the glass down in the pipe.  O2 works because it's half of the thermal conductivity.

I just tried placing the glassmaker in vacuum. It heats around 7 C (this will likely depend highly on building material). It seems that it's viable to use a vacuum to prevent cooling the pipes and then "drown" the building a night to reset the temperature. I'm far from certain that I would recommend that people do that, but it would certainly solve the issue of cooling the pipes too aggressively.

Also if you fear overheating the building, you can use the Building Temperature Sensor. If you set it to below say 70 C, then then the building will disable itself before overheating.

[Craigjw]

I've upped the O2 to about 1100gs using 2 Weezes and have been making as much glass as I can and it seems to be holding up so far.  The issue seems to be the Hydrogen being to thermally conductive.

In my tests, pipes will break eventually all the time, when it is too long. And by "too long" i mean, even if its just below the foundation of the glass forge, into a vent. My working solution for now is, pipe from output to the right, next to the forge a vent, so the pipe is just 2 tiles long, and then a vent. beneath a mesh tile to let the liquid glass fall down. Never broke since i do it that way.

[Nitroturtle]

It was likely hydrogen cooling down the machine too much causing the internal glass to cool and immediately break the first pipe it reached.  When it's the first pipe that's breaking, typically it's the internal storage that's the issue. 

[Lancar]

I've never had the problem of the pipes to my glass forges ever breaking, but then i realized I always placed it near the bottom of my base so it was frequently immersed in waste chlorine. That stuff has really bad thermal conductivity, so must've been the reason.

[Denisetwin]

I have this problem all the time.  The exit pipe breaks at the exit point.  Pain in the behind. 

[JohnFrancis]

The most common cause of pipe breaks with glass is not the pipes it's the glass forge itself. While the glass is making it exchanges heat with the refinery and the surrounding environment. So by the time the animation is complete and the glass goes to exit it has already lost to much heat and instantly cracks pipes.

Most common issues

1. You have liquid touching the glass forge, massively increases conductivity, instant pipe breakage.
2. You place the glass forge on very conductive tiles like metal or diamond.
3. You have the glass forge in a heavily pressurized, conductive gas environment. Bonus breakage if the gas is cooled.

To be safe, Ceramic forge on top of insulated tiles, you can get away with most gasses at that point but I find oxygen is fine.
