Setting Up Fluid Transport in Immersive Engineering
Fluid pipes in Immersive Engineering are how you move liquids between machines without hauling buckets. They use a pump to pressurize flow, and once you understand the basics, they save you from a lot of manual work. The system isn't perfect. I've spent enough time debugging my chemical mixer setups to know where things break. The first thing you need is a Pump. Place it down, give it power with a Motor or Steam Engine, and it starts pulling fluid from any connected source. From there, you lay Pipe Segments or Pipe Joints to route the fluid where it needs to go. The pump creates pressure, and pressure pushes fluid through the network. That's the core loop. I used to run everything at max speed, thinking faster was better. That was wrong. When you push fluids too hard through a long network, you get pressure drops, and machines downstream starve. The fix is using multiple pumps in parallel rather than one mega-line. Split your output at the source, feed two separate routes to the same machine bank, and each line maintains its pressure. My Slaughter Machine farm runs twice as reliably this way now.
There's a detail most people miss about flow rates. Fluid pipes have a fixed transfer speed, but it's measured in millibuckets per tick, not per second like you might expect. A single pipe segment moves roughly 100 mB/t in each direction. If a machine produces more than that, you need to split the output across multiple parallel pipes or you'll create a bottleneck. The Squeezer outputs about 168 mB/t of juice. One pipe isn't enough. Two pipes handle it cleanly. Another thing nobody mentions: cross-contamination. If you run two different fluids through interconnected pipes without valves, they mix in your tanks. You'll wake up to a tank that's supposed to hold water now holding a fifty-fifty mix of water and liquid XP because a pipe junction was shared. Install Check Valves on each input line going into a storage tank. They cost copper cable and iron, but they prevent disasters. For routing, Pipe Joints give you more flexibility than Pipe Segments. Segments are rigid and only connect in cardinal directions. Joints let you branch off at angles and route around obstacles. I use joints for the messy parts of my setup and segments for straight runs. It's a minor optimization but it makes debugging a thousand-block network significantly easier.
If you need to route fluids through walls or ceilings, use Cable Fans in conjunction with your pipes. They don't carry fluid themselves, but they pull the connected pipe network through blocks so you can hide your plumbing inside structures. Looks cleaner and protects pipes from things like explosion damage if you're running near industrial explosives. The biggest limitation of this system is that Immersive Engineering fluid pipes can't lift fluid against gravity on their own. A pump pushes horizontally, but if your destination tank is above the source, the fluid won't climb unless you place additional pumps at intermediate heights. I once built a three-story processing tower and spent two hours wondering why nothing was moving upward. Added a pump on each floor and the whole system came alive. Factor in vertical head when designing layouts. Download the mod from the standard sources like CurseForge or Modrinth. Make sure your Immersive Engineering version matches your Minecraft version. Fluid pipe behavior has changed between versions, so if you're playing a newer build and following an older tutorial, some of this may not apply exactly.

The system works well once you stop treating it like a simple conveyor belt. It's a pressure-based network with real bottlenecks, and respecting those constraints is what separates a functional setup from one that randomly starves halfway through automation.
