On the subject of atmospheric pipes

[Musketman12]

I think that the pressure limit in atmospheric pipes should be increased, as the limit right now (somewhere around 15,000 kPa from what I can tell) makes it hard to get a lot of gas really hot in toxins, and especially on Destiny it makes running engineering with a combustion chamber burn quite difficult. It's also quite low for real world pressures. 15,000 kPa is somewhere around what a scuba tank holds. You'd think that on a soaceship they'd have better pipes.

Just open the vent valves that lead into space, releases most of the pressure and keeps the heat. Destiny I have no clue about however since I have never used toxins on Destiny.
