SamLogan Posted August 9, 2018 Share Posted August 9, 2018 Hello, I did some tests and found a weird thing, bridge in abyssalite seems to heat more the environnement than sandstone : Why the hydrogen is 0,3°C higher with the abyssalite? The water source is the same and come from an abyssalite pipe. Link to comment Share on other sites More sharing options...
BlueLance Posted August 9, 2018 Share Posted August 9, 2018 Abyssalite is no longer a perfect insulator, and bridges are not insulated. So they act as a normal abyssalite pipe as far as i am aware Link to comment Share on other sites More sharing options...
Alex_D Posted August 9, 2018 Share Posted August 9, 2018 Since almost all materials for bridges (liquid, gas, belts) have a very low overheat temperature, now, when possible, pretty much bridges of all kinds are done with abyssalite for me.

I use ceramic. Same +200C bonus and save on abyss mats. Link to comment Share on other sites More sharing options...

Ceramic let the heat leave it 100 times quicker than the abyssalite : 0,620 vs 0,00001. Link to comment Share on other sites More sharing options...

So while it may be worse at insulating, the reduced thermal capacity could very well make up for it. Link to comment Share on other sites More sharing options...

It just teleport it from input to output. The only thing that interacts is the mass of bridge itself. I see zero point wasting abyssalite on a bridge.

SamLogan Posted August 9, 2018 Author Share Posted August 9, 2018 The problem is abyssalite bridge produce heat ! o_O Link to comment Share on other sites More sharing options...
Sevio Posted August 9, 2018 Share Posted August 9, 2018 While the screenshot in the OP does look strange to me, please don't go on a wild Goose chase everyone Liquids going through bridges actually "jump" from pipe to pipe, they don't interact with the bridge at all. Here I am pumping 1726.9 C magma through a bridge made of plain old Igneous rock. The bridge is in vacuum to exclude temperature transfer with the environment and the pipes are insulated abyssalite. It's been going for a full cycle and the bridge has not changed temperature at all from its starting 20 C. Yes, I tried it with an abyssalite bridge too and there was no effect. @SamLogan My guess as to what happened in your picture: You built a bridge using debug mode in warm hydrogen. Debug-built objects always start at 20 C. So the abyssalite has barely changed and the hydrogen is still at the same temperature that it started with, where the ceramic bridge has warmed up to the temperature of the hydrogen and the hydrogen has cooled down a bit to heat up the ceramic bridge.

Scorpio King Posted August 9, 2018 Share Posted August 9, 2018 I did the same thing, every number remained. Link to comment Share on other sites More sharing options...

Sevio Posted August 10, 2018 Share Posted August 10, 2018 @habuky It's because the mini pump doesn't actually touch the magma that it works, as long as you can get it to "see" liquid. The liquid detect range is a square while the pump range is a diamond shape, have a look at this to understand how it works: Note that while the mini pump version works, it cannot be cooled while pumping so it is doomed to heat itself up and break after pumping about 2-3 tiles of magma. If you want to pump a lot of magma, fast, you're better off trying the big pump version that uses naphtha. Link to comment Share on other sites More sharing options...
