Reinforcing atmospherics pipes and materials via chemicals.

The only real problem is that you'd have to apply it to each pipe segment. While it would definitely increase the difficulty of doing it to prevent just everyone from making super hot hellburns, which should always have -some- barrier to entry (or else they're not special and something to strive for), a slight slant on that would instead have it be a kind of gas that could be in a tank found in space. There is another thread about space exploration not being worth it, and the ability to make your gas pipes stronger by pumping a quick spurt of some anomalous gas through them would fit both of these needs, I think. That said, it's entirely possible that gasses simply can't be made to behave that way and it'd be a coding nightmare, in which case I definitely think the chem should be made instead.

The biodome gas sort of fills that role already, however it's a pain to get in a normal round if you're an engineer.

Also it doesn't help deal with bursting pipes, but I doubt much will

That gas only makes it easier to get higher temps faster, it will still burst pipes real quick.
