Pipe

Lore & Background

In the world of the Factorio protagonist, the planet is rich in raw resources but utterly devoid of any existing infrastructure. Every conduit, every channel, every drop of transported fluid must be laid by hand. The pipe, in this context, is not merely a game item but a fundamental act of civilization: the decision to move a liquid from where it is extracted to where it is needed, and to do so reliably, at scale, in perpetuity. The alien world is dotted with oil lakes, water sources, and mineral deposits, but none of them are useful without a way to carry their contents to processing facilities. The pipe fills that gap with elegant simplicity. It does not transform, refine, or store for long; it merely connects. Yet in a factory that might contain thousands of machines, the pipe network becomes a vast, interlocking web that is as complex as any circuit board, and its failure—whether through a biter attack or a misplaced tile—can cascade into a full production collapse. Fans often describe the moment of watching a long pipe line fill with flowing oil for the first time as one of the game's small, quiet triumphs. There is no fanfare, no achievement chime—just a steady blue current moving through the landscape, telling you that the machine at the far end will, at last, begin to work.

In Their Own Story

The rain had stopped, but the pipes still ran. Kael crouched beside the oil pump, watching the crude seep into the first segment, then the second, then the long grey-blue line snaking toward the refinery three hundred meters away. The biters had chewed through the eastern belt line an hour ago, and the whole solid-item chain was dead. But the fluids—fluids were still moving. The refinery hissed and spat, turning black sludge into something brighter, something that would feed the chemical plant, which would feed the plastic, which would feed the rocket parts that would, eventually, take him off this wretched rock. He tapped the pipe with his wrench. It hummed faintly, pressurized, alive in its own mechanical way. "Keep flowing," he muttered. "I'll fix the rest tomorrow."

The pipe did not answer. It simply carried the oil forward, one hundred units at a time, into the waiting dark of the refinery's intake port.

Function: The Pipe transports fluids between machines that have fluid input or output ports. It does not process, filter, or store fluids long-term; it simply provides a connected pathway. Fluids flow from a source (oil pump, water pump, or a machine's output port) through the pipe network to a destination (refinery input, chemical plant input, or another machine's input port). Input/Output: Pipes themselves have no discrete input or output slots. They connect to fluid ports on adjacent machines. A pipe placed next to a machine's fluid interface will automatically link to that port. Throughput is governed by the machines at either end of the network, not by the pipe itself. However, placing multiple pipes on the same tile (stacking) increases the total buffer and effective throughput, which matters when a single machine's pump rate exceeds what one pipe segment can relay. Power: Pipes consume no electricity. They are purely passive infrastructure. Technology: The basic Pipe is available from the earliest stages of the game, making it one of the first infrastructure items a player will craft and place. Adjacency and quirks: Pipes must form a connected path between source and destination. They can turn corners, branch, and loop. A broken segment (destroyed by biters or removed by the player) severs the network and halts flow. Pipes do not require a clear line of sight; they simply need to be adjacent or connected tile-by-tile. When planning a factory, route pipes to minimize length (each segment adds buffer but also adds a point of vulnerability) and keep them accessible for repair.

Did You Know?

• Pipes consume zero power, making them the only fluid-transport method in the game that requires no energy input—unlike every machine they connect to.
• Stacking multiple pipes on the same tile is the primary way to increase fluid throughput in a network; a single pipe can become a bottleneck if the source pumps faster than the network can relay.
• A pipe network is only as strong as its weakest link: a single destroyed segment, whether from biter attacks or player error, severs the entire connected path and halts all fluid flow in that branch.
