Troubled by pipes having low flow rates?
Flow rates still low even though using a lot of pumps?
Lots of pipes for nuclear power hurting the UPS?
This mod will help you a lot! Scaled up versions (called "overtiers") of various pipes and pumps are introduced. These wide pipes and pumps have much higher max flow rates, scaled like the machine overtiers in Schall Machine Scaling mod. Thosee high overtier nuclear reactors (and its heat exchangers and steam turbines) will also required these overtier offshore pumps, heat pipes to feed enough water and heat through those machines, in order to work to their full capabilities.

Each higher tier is exactly 4 pipes/pumps of its lower tier, in terms of flow rate, power consumption, or any other properties. The only difference is they are combined into a single pipe/pump, thus effectively reduce the number of entities on map. This ratio is exponential, meaning you will cut the total number of entities even further with very high tier machines. (For example, overtier +4 is exactly 256× of vanilla machine.)
The overtier pumps work even a bit better than that (e.g., 6.4× of vanilla pump instead of just 4× for "pump +1"), so they should have more than enough capabilities to move fluids within your factory.


For example, a "offshore pump +4" is effectively 256× vanilla offshore pump in terms of flow rate. If your megabase is currently having about 2000 vanilla offshore pump (along with pipes supplying water to the heat exchangers), with this mod you can replace these offshore pumps with just 8 "offshore pump +4"! It would be the best if you replace all the pipes with "pipe +4" as well, the UPS hit caused by fluid flow calculations should be minimized by a big margin!
The related entities should use the same overtier to take the best effect. In the above example, it would be the best to use "heat pipe +4", "heat exchanger +4", "steam turbine +4" (or "pump +4") as well.
The only exception is nuclear reactor, which should have 1 or 2 tier lower than the rest, to reduce the total number of entities to improve UPS.

For example, you can easily obtain 1.9 TW (yes, TERAWATT!) power from 4× nuclear reactor +6 (in 2×2 configuration), 2× offshore pump +7, 12× heat exchanger +7, 21× steam turbines +7, with various pipe +7 and heat pipe +7 to connect the entities.
More examples (with pictures and blueprints) are available in FAQ section.

Overtiers of heat pipes are only available if you have enabled Schall Machine Scaling mod, since they are meaningful only if you are using the overtiers of nuclear reactor and heat exchanger there.


Players may find the pipes (and the whole fluid system) do not work as what they expected. Unexpected low flow often comes from incorrect concepts.
Please see some in-depth documentations online to understand the Factorio fluid mechanics better.

Even if you are familar with vanilla fluid mechanics, this mod provides more than that. Following the below guidelines will help you master the use of overtier pipes and pumps.

  • Avoid using larger pipes than you needed. A relatively "empty" (few fluid) pipe have low pressure, so barely any flow. Use a narrower/smaller pipe if you do not have that much fluid to fill. For example, when taking water input from a vanilla offshore pump, using pipe +3 will actually be slower than vanilla pipe. (Concept of fluid pressure is explained in the above-mentioned documentation.)
  • Max pressure are scaled with the tier. For example, vanilla pipe has max pressure of 1. Pipe +1 has max pressure of 4. Pipe +n has max pressure of 4^n.
  • Storage tanks (from Schall Machine Scaling) is the only exception. They always have max pressure of 1. Their base area are scaled instead, to provide the increased total capacity. (Concept of base area is explained in the above-mentioned documentation.)
  • Use pumps to take fluid out of storage tanks, to ensure high flow. This is because storage tanks have large "base area", thus inherently low pressure by itself. Use pumps will force one-way flow, mitigating the pressure problem.
  • Use matching tiers of entities (offshore pumps, pipes, pumps, etc.) very often gives the best result. Too large difference (e.g., excessive large pipes from a small pump) almost ensures less flow than you could ever imagine.
  • It is recommended to connect with a high tier pump, when having to transfer fluid from low tier pipe (and all storage tanks) to high tier pipe. This is caused by the difference is maximum pressure. Fluid in low tier pipe does not have enough pressure to fill high tier pipe, so cannot use to its full capability.
  • Pressure drops along a line (sequential) of pipes. Use pipe to ground (counts as two fluidboxes, disregarding actual distance) to reduce the length, or use pump to keep pressure high.
  • Avoid mixing low base level entities (e.g., steam turbine) with high base level entities (e.g., pipes). A classic negative example is "steam turbine - pipe - steam turbine". It requires extra pressure in the first steam turbine to reach the second steam turbine. The pipe essentially acts as a barrier here, lower the flow rate. In this case, try to place them right next to each other, or use a pump in place of the pipe. (Concept of base level is explained in the above-mentioned documentation.)

Known Issues

  • Fluid wagon connector of overtier pumps do not work. It seems the fluid wagon detection and connection is somehow hard-coded in vanilla pump, I cannot get it working on overtier pumps. But since fluid wagon has quite small capacity, while vanilla pump is already very fast to load empty wagon / unload full wagon (just merely a few seconds), so I do not feel much need to fix it. Simply use vanilla pump to handle fluid wagons.

Mods Dependencies

  • Schall Machine Scaling is optional but highly recommended, since the high flow rates pipes and pumps are only useful if you have machines really need that capability. Use together to improve UPS of your megabase even further!
  • Schall Machine Modification is optional but useful, since this mod provides high throughput fluid boxes to the overtiers over those modified machines.
  • Schall Starting Inventory is optional but useful, since it allows adjusting starting invenotry, like some offshore pump +2 and pipe +2 as initial items.

  • Thanks to Linver and mod Fluid Must Flow. His mod has inspired me and make me realize that pipes can use larger size as well (instead of just vanilla 1×1)! Yet this mod is built from scratch using vanilla code, without using his code.
  • Thanks to GotLag and mod Flow Control. His code has some efficient part that can help improve my code a bit, in some early pre-release stage. Those parts are finally unused in my first release version 0.17.0, but still I have to thank for granting me the kind permission.
