Frankly, it's just a bunch of pipes, bended in a mind bending way.

There are two variants, straight and corner. This allows for flexible layouts.

Straight:
44l - 28 CP I (lvl 1 pipes)
98l - 28 CP II (lvl 2 pipes)
165l - 28 CP III (lvl 3 pipes)
219l - 42 CP III 70 steel (lvl 4 pipes)

Corner:
42l - 28 CP I (lvl 1 pipes)
94l - 28 CP II (lvl 2 pipes)
159l - 28 CP III (lvl 3 pipes)
210l - 42 CP III 70 steel (lvl 4 pipes)

Note: Corner pieces have less volume, as you notice.
Note 2: The largest storages consisting of lvl 4 pipes aren't really worth the extra resources compared to lvl 3 pipes.
