Stone Irrigation Pipe - Straight

A straight run of stone pipe

The Stone Irrigation Pipe (Straight) is a stone segment of an irrigation network. That is its name in ARK: Survival Ascended; ARK: Survival Evolved calls it Stone Irrigation Pipe - Straight. The in-game text reads: "A straight stone pipe for an irrigation network, used for transporting water across land."

Engram, recipe and weight

The engram unlocks at level 17 for 2 engram points. Each pipe is made in the inventory from 5 Stone in 3 seconds. A pipe weighs 1 and they stack to 100, so a full stack weighs 100. Loot is another source: 52 crate types can contain it, for example the Aberration White crates of Aberration and Valguero, the Fjordur Green crates and the Genesis Blue crates of Genesis Part 2.

What it connects to

You can set it on a foundation or a ceiling, or attach it to another pipe. According to the ARK Wiki, placing it on foundations and ceilings mostly helps when you want irrigation lines that sit neatly in rows, above all in farms. It snaps to stone and metal pipes of the straight, intake, tap, vertical, inclined and intersection kinds, to a stone or metal Water Reservoir and to the Industrial Cooker.

Damage it ignores

The game treats the pipe as a wooden structure: bare hands, stone weapons and ranged attacks without explosives cannot damage it. A long list of aggressive creatures cannot hurt it either; the wiki names the Raptor, Sabertooth, Direwolf, Titanoboa, Pulmonoscorpius and Kaprosuchus among them.
