Fluids and Pipes
How liquids and gases move: pipelines and pumps, headlift, packaging fluids onto belts, and the 1.2 Fluid Trucks that move liquids without pipes.
Fluids are Satisfactory’s second logistics system, separate from belts and with their own rules. Water, crude oil, fuel, acids, alumina solution, and nitrogen gas all move through pipelines rather than on conveyors, and pipes behave differently enough that they trip up players who treat them like belts. The key differences are that fluid needs pumps to climb, that a line can stall if it is not headlifted or buffered correctly, and that you have alternatives to piping entirely. Get the fluid system working and the oil, aluminum, and nuclear chains open up. Misjudge it and a refinery complex sits starved while its pipes sit half full.
Pipelines and pumps
Pipelines unlock alongside Coal Power in Tier 3, which is also where fluids first matter, since coal generators need water. Fluid flows downhill and across level ground on its own, but to send it uphill you need Pipeline Pumps, which add headlift to push fluid above the pump’s position. Pipeline Mk.2, in Tier 6, carries more than the Mk.1 line. The exact throughput figures for Mk.1 versus Mk.2 were not pinned down in research, so check the wiki before quoting precise rates. The recurring beginner mistake is forgetting that fluids need pumps to climb, then wondering why a line that crosses a hill never fills.
A fluid line that is not headlifted or buffered correctly can stall even when there is plenty of fluid at the source. When a pipe will not fill, suspect the headlift first: check that pumps cover every climb and that buffers smooth the flow before blaming the supply.
Packaging fluids onto belts
Fluids do not have to stay in pipes. The Packager, unlocked in Tier 5, bottles a fluid into canisters or tanks so it can ride a belt or sit in a truck or freight car like any other solid item. That makes packaging the bridge between the fluid system and the belt and vehicle systems. It is the answer when you need to move a liquid somewhere a pipe cannot easily reach, or carry it on a train alongside solid cargo.
Fluid Trucks, the 1.2 pipe alternative
The 1.2 update added Fluid Stations and Fluid Trucks as an alternative to pipelines for moving liquids over distance. Both have 3200 m3 of internal storage, and they unlock in the Logistics Mk.4 milestone area of the tree. They let you move fluid across the map without laying and headlifting a long pipeline, which is especially useful over awkward terrain. Note a source conflict worth flagging: the 1.2 patch notes describe Fluid Stations and Trucks as unlocking at Tier 5 as part of Logistics Mk.4, while the wiki lists Logistics Mk.4 under Tier 6. Treat the exact tier as unconfirmed until you check the live wiki.
Where fluids feed the factory
| Fluid | Used for |
|---|---|
| Water | Coal and nuclear generators, alumina and many recipes |
| Crude Oil | Plastic, rubber, and fuel in the Refinery |
| Alumina Solution | The bauxite-to-aluminum chain |
| Nitrogen Gas | Late-game blender and nuclear recipes |
| Fuel and Turbofuel | Fuel Generators |
The Refinery handles crude oil recipes and the bauxite chain and has both pipe and belt connectors. The Blender, a late-game building, mixes fluids and solids with two pipe and two belt inputs. Because so many power and late-game chains depend on fluid, the fluid network is not a side system: it is load-bearing for everything from your first coal plant to the exotic-matter endgame.
