Do we need to build insulated pipes from insulationr?

[SharraShimada]

So, insulation (material) is virtual not capable to transfer heat. 

Does it makes sense to build insulated pipes from insulation, or does a normal pipe made from it work too?

The reason is, insulated pipes use 4 times the amount of material compared to normal pipes. And insulation is rare.

[KittenIsAGeek]

Insulated pipes made from Insulation are basically the perfect insulator.  You can certainly build insulated pipes out of other materials.  Ceramic is relatively cheap and does a wonderful job.   Other materials don't do quite so well, but insulated sandstone is very cheap and works 'well enough' until you can get ceramic.

I need insulation for a specific reason. LOX and liquid hydrogen. And for that i need perfect insulation. The question is, is non-insulated pipe made from insulation as good as insulated pipe made from insulation?

[Neotuck]

can you use a vacuum? 

Might be easier to transport LOX and LH2 in a radiant pipe though a vacuum

No, it isn't as good.  Making regular pipes with insulation does work, but not nearly as well as insulated pipes made from insulation.

That's a good alternative.

[Neotuck]

Ok I did a quick test with both pipes pumping LH2 though magma, one normal and one insulated.  Both made with insulation material.

The LH2 in the normal pipe was 0.4 degrees warmer than the insulated one

Unfortunately there is vacuum but not in the entire area. So i need perfect insulation ^^. Thanks for the replys.

(asking to learn) why radiant inside a vacuum over regular pipe or insulated (inside a vacuum)?

you'll need the pipe to be the same temp as the contents, radiant pipes will equalize faster than normal pipes and the vacuum will keep it perfectly insulated

I first did this to transport steam to my first rocket

You just give me an idea, why not precool the radiant pipe so temp is already good.

you could probably precool the metal before building it

What happens over time if you run something hot/cold with insulated pipes through a vacuum?  Or even using, say, normal sandstone pipes, because vacuum. (I did this with hot water from a geyser spawn against my base, insulated piping with with two wide insulated tiles on base side. I'm curious what impact it may be having).

don't forget that there a caps for precooling stuff because the building resets to a certain range...

as long as it's a vacuum the pipe will only exchange heat with it's contents

I have never heard of this

I see, but something as important as lox or LH is to keep cool, this actually chills the pipe? Playing this game for 2 years and I still always feel like I know nothing lol.

if it's an insulated pipe it will take a long time but yes it will cool

unless you use a perfect insulator like insulation

just tested it, spawned in 100kg sandstone at -270°C and another 100kg sandstone at 750°C

let a dupe build ladders from it: the cold one is 15°C, the hot one is 45°C

in a vacuum?

yes

[SharraShimada]

Yes, this is a know exploit to get rid of really high heat. Just build something from it, and the heat is gone...

Ok you learn something new each day :=)

I believe that sandstone insulation tile has the same thermal conductivity as oxygen (has). So..... I will want better than sandstone.

i usually use igneous, cuz it’s cheap and good enough. But ceremic definitely is the best and relatively available

Insulated sandstone has a thermal conductivity of 0.029.  Oxygen has a thermal conductivity of 0.024.  So.. oxygen is a slightly better insulator than insulated sandstone.  EXCEPT that because it's tagged as an insulator because of the tile, heat will always transfer to insulated sandstone using the lowest thermal conductivity.  Oxygen, on the other hand, will use the log average.

[fishoutofwater]

I believe I read someone's post in this forum said that 'insulated' use the material conductivity while 'normal' use the average, so if you want perfect insulation you need insulation insulated. CMIIW

[goatt]

@KittenIsAGeek yeah I know sandstone insulation tile is actually better than oxygen in most cases, but good to know about the underlying code. But i would still recommend using tiles at least ceramic level for system under extreme heat. Normal use igneous is fine.
