- Or: What the fuck does a "passive gate" do?
+ Or: What the fuck does a "pressure regulator" do?
Alright. It has come to my attention that a variety of people are unsure of what a "pipe" is and what it does.
Apparently, there is an unnatural fear of these arcane devices and their "gases." Spooky, spooky. So,

Manual T-valve: Like a manual valve, but at the center of a manifold instead of a straight pipe.
+ An important note here is that pipes are now done in three distinct lines - general, supply, and scrubber. You can move gases between these with a universal adapter. Use the correct position for the correct location.
+ Connecting scrubbers to a supply position pipe makes you an idiot who gives everyone a difficult job. Insulated and HE pipes don't go through these positions.
Bent pipes: Pipes with a 90 degree bend at the half-meter mark. My goodness.
Pipe manifolds: Pipes that are essentially a "T" shape, allowing you to connect three things at one point.

They actually do something.
This is usually where people get frightened, afraid, and start calling on their gods and/or cowering in fear. Yes, I can see you doing that right now.
Stop it. It's unbecoming. Most of these are fairly straightforward.

- Gas pump: Take a wild guess. It moves gas in the direction it's pointing (marked by the red line on one end). It moves it based on pressure, the maximum output being 15000 kPa (kilopascals).
Ordinary atmospheric pressure, for comparison, is 101.3 kPa, and the minimum pressure of room-temperature pure oxygen needed to not suffocate in a matter of minutes is 16 kPa
- (though 18 kPa is preferred using internals, for various reasons).
- - Volume pump: This pump goes based on volume, instead of pressure, and the possible maximum pressure it can create in the pipe on the receiving end is double the gas pump because of this,
- clocking in at an incredible 9000 kPa. If a pipe with this is destroyed or damaged, and this pressure of gas escapes, it can be incredibly dangerous depending on the size of the pipe filled.
- Don't hook this to the distribution loop, or you will make babies cry and the Chief Engineer brutally beat you.
- - Passive gate: This is essentially a cap on the pressure of gas allowed to flow in a specific direction.
- When turned on, instead of actively pumping gas, it measures the pressure flowing through it, and whatever pressure you set is the maximum: it'll cap after that.
- In addition, it only lets gas flow one way. The direction the gas flows is opposite the red handle on it, which is confusing to people used to the red stripe on pumps pointing the way.
+ (though 18 kPa is preferred when using internals with pure oxygen, for various reasons). A high-powered variant will move gas more quickly at the expense of consuming more power. Do not turn the distribution loop up to 15000 kPa.
+ You will make engiborgs cry and the Chief Engineer will beat you.
+ - Pressure regulator: These replaced the old passive gates. You can choose to regulate pressure by input or output, and regulate flow rate. Regulating by input means that when input pressure is above the limit, gas will flow.
+ Regulating by output means that when pressure is below the limit, gas will flow. Flow rate can be controlled.
- Unary vent: The basic vent used in rooms. It pumps gas into the room, but can't suck it back out. Controlled by the room's air alarm system.
- Scrubber: The other half of room equipment. Filters air, and can suck it in entirely in what's called a "panic siphon." Activating a panic siphon without very good reason will kill someone. Don't do it.
- Meter: A little box with some gauges and numbers. Fasten it to any pipe or manifold and it'll read you the pressure in it. Very useful.
- - Gas mixer: Two sides are input, one side is output. Mixes the gases pumped into it at the ratio defined. The side perpendicular to the other two is "node 2," for reference.
- Can output this gas at pressures from 0-4500 kPa.

Will not set you on fire.
These systems are used to only transfer heat between two pipes. They will not move gases or any other element, but will equalize the temperature (eventually). Note that because of how gases work (remember: pv=nRt),
a higher temperature will raise pressure, and a lower one will lower temperature.

Pipe: This is a pipe that will exchange heat with the surrounding atmosphere. Place in fire for superheating. Place in space for supercooling.
Bent pipe: Take a wild guess.
Junction: The point where you connect your normal pipes to heat exchange pipes. Not necessary for heat exchangers, but necessary for H/E pipes/bent pipes.
Heat exchanger: These funky-looking bits attach to an open pipe end. Put another heat exchanger directly across from it, and you can transfer heat across two pipes without having to have the gases touch.
- This normally shouldn't exchange with the ambient air, despite being totally exposed. Just don't ask questions...

That's about it for pipes. Go forth, armed with this knowledge, and try not to break, burn down, or kill anything. Please.
