Pipes (Below Zero)

Pipes and the Floating Air Pumps are crafted by using the Fabricator. They allow the player to pump Oxygen from the surface.

The Base-attached Air Pump can be constructed using the Habitat Builder, which allows the player to pump Oxygen from a Seabase instead of the surface. This may be a more preferable choice for areas too deep to use the Floating Air Pump.

Note that the function of pipes and air pumps is not to supply a base with oxygen, but to create a location underwater where breatheable air is accessible to the player. Pipes cannot supply a base with oxygen.

Usage
Pipes allow the player to create a network of interconnected Pipes with readily available Oxygen underwater.

The Base-attached Air Pump pumps Oxygen through Pipes from a Seabase without the need to place Pipes at the surface.

A Pipe must be connected to an Air Pump in order to carry oxygen. A player's Standard O₂ Tank will start filling once they swim near an active Pipe.

How to Use

 * 1) Place a Floating Air Pump above the water.
 * 2) Connect a Pipe to the Floating Air Pump. The Pipe will be shown at the end of the first Pipe.
 * 3) The Base-attached Air Pump can be placed on a Seabase to pump oxygen through Pipes without having to place Pipes at/from the water surface.
 * 4) If the player swims near the end of a Pipe, they will automatically receive Oxygen.

Recipe
The blueprint for the Pipe is unlocked by crafting a Standard O₂ Tank. It is crafted in the Fabricator.

The blueprint for the Floating Air Pump is unlocked by crafting a Standard O₂ Tank. It is crafted in the Fabricator.

The blueprint for the Base-attached Air Pump cannot yet be unlocked. It is crafted with the Habitat Builder.

Trivia

 * The Databank Entry image for the Floating Air Pump displays an incorrect representation of diatomic oxygen, showing it with five valence electrons on each oxygen atom and a single bond between the two, when there should only be four valence electrons on each and a double bond between the two oxygen atoms.
