In order to quickly have a liquid pipe with very low heat exchange at the output of my oxygen liquefaction room, waiting for enough material for insulated version, I made a standard pipe with insulation (100 kg instead of 400).
But even if the thermal conductivity is 0.000, this pipe is worse then an insulated pipe made out of igneous rock that have thermal conductivity of 0.063. O_o
Just look :
With standard pipe made out of insulation, the liquid oxygen only reach the third section out of the room.
And now, the same pipe but insulated with ingeous rock :
As you can with the damages and the full tank, even with higher thermal conductivity, the insulated pipe of ingeous rock bring the liquid oxygen to the tank, where the standard pipe just throw it in the vaccum ...
I understand that a standard pipe could have some heat exchange, even made out of insulation, but here ... it's just a massive heat exchange for a pipe in vaccum with 0.000 thermal conductivity. :-/
build a standard pipe with 'insulation'
