I know greg ignores this alot, but outer people dont
how about give invar cover a feature? like making the simple plate when placed in a fluid pipe block the damage from steam, and a dense plate block the damage from lava. the reason is simply because invar blocks are heat proof, so i believe the same could be said about the plate. Or we could get a crafting of a pipe with invar plates around to make a invar convered pipe, or simply invar pipes with less fluid than steel but heat proof.
Also, lately i am having trouble to figures out how gt e-net work with diferent machines request/batterys/ic2 machines, so i cant find how to set to always go to one first them later outer, so how about a especial cable to have a higher priority than the outers? we have a pipe to make pipeline better, and we do have a way ti make fluid pipes more effective, only remaining the gt e-net without a way to optimize without just dumping more losses.
Invar isn't heatproof. It merely does not expand upon heating. In fact, it conducts heat better than something like styrofoam.
