usually lilypipes has 3 different sizes: 10mm, 13mm, 17mm (outer diameter)
and hose commonly has 3 sizes: 9/12, 12/16, 16/22 (inner/outer diameter)
lily 10mm fit with 9/12 hose (9mm inner diameter / 12mm outer diameter)
lily 13mm fit with 12/16 hose (12mm inner diameter / 16mm outer diameter)
lily 17mm fit with 16/22 hose (16mm inner diameter / 22mm outer diameter)
so nothing to worry about lilypipe inner diameter
hope will help

and if 13mm is the outer diameter, what would be the inner diameter of the lily pipe?
depend on brand, ADA lily pipe glass has appx 2mm thick, other brand usually thinner than that. So just say lily 13mm has 9-10mm inner, and 17mm has 13-14mm inner diameter.
But I'm curious, why you concern with lily inner diameter?
these link compare between ANS 13mm lilypipe vs PowerMan 13mm lilypipe:

I have 4 tank in my room, 3 using ANS and other one using PowerMan.
ANS lily has very smooth finishing, and very look alike ADA lily.
PowerMan has thin glass, man made finishing, and at the box printed "made in Aust
uralia" instead Australia
. in my powerman sand flattener packaging also printed Aust
uralia, LOL
ANS 13mm cost me about USD 36 /pair
PowerMan 13mm about USD 28 /pair
