Pipe16XS pipe

Detailing dimensions and section properties from the AISC Shapes Database, 16th Edition. Values are shown to the nearest 1/16 in. as they appear on a shop drawing.

Pipe16XS has a 16 in. outside diameter and a 1/2 in. nominal wall.

Also known as NPS 16 pipe (16 in. nominal), extra strong (XS) wall.

At 82.9 lb per foot it is the heaviest of the 2 Pipe16 sizes, which run from 62.6 to 82.9 lb/ft.

For strong-axis bending its section modulus is Sx = 83.1 in³ and its moment of inertia Ix = 665 in⁴, with a plastic modulus Zx = 109 in³.
