Fluid Must Flow - Upgraded Ducts
An add-on for Fluid Must Flow (by raiguard) that adds three upgrade tiers to the duct intake, the duct exhaust and the non-return duct. Each tier doubles the throughput of the one below it, and each is gated behind a different Space Age planet.
Tiers
The non-return duct connects only to ducts, so nothing throttles it but its own rating. However, the intake and exhaust each have six normal-pipe connections, and every segment-to-fluidbox connection in Factorio 2.0 is hard-limited to 6,000 fluid/s, so those two can never deliver more than 36,000 fluid/s however fast the pump is rated. Measured with six creative pipes, the real figure I measured flattens out around 25,200. The tiers are built around that. If anyone else knows better, please let me know.
The non-return duct starts a tier ahead as a result. A single duct network can be fed by several intakes at once, so its total flow is a multiple of the endpoint ceiling rather than being bounded by it, and a non-return duct in that network has to carry the combined load. This might need to be adjusted, depending on feedback.
| Tier | Intake / exhaust | Non-return duct | Made on | Made in |
|---|---|---|---|---|
| Standard (Fluid Must Flow) | 7,200 fluid/s | 7,200 fluid/s | Nauvis | Assembling machine |
| Fast (red) | 14,400 fluid/s | 28,800 fluid/s | Vulcanus | Foundry |
| Express (blue) | 25,200 fluid/s | 57,600 fluid/s | Fulgora | Electromagnetic plant |
| Turbo (green) | 36,000 fluid/s | 115,200 fluid/s | Aquilo | Cryogenic plant |
Powered pumps draw 271 / 376 / 463 kW against the standard 181 kW. The non-return duct needs no power at any tier, mirroring Fluid Must Flow.
Each tier is built from the one below it, so upgrading a network is a matter of feeding the previous tier back into the recipe. All four tiers share a fast-replace group and are chained with next_upgrade, so the upgrade planner walks the whole ladder.
