Pipe1/2XS 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.

Pipe1/2XS has a 13/16 in. outside diameter and a 1/8 in. nominal wall.

Also known as NPS 1/2 pipe (1/2 in. nominal), Schedule 80 (XS) wall.

At 1.09 lb per foot it is one of the 8 Pipe1 sizes, which run from 0.85 to 3.63 lb/ft.

For strong-axis bending its section modulus is Sx = 0.0462 in³ and its moment of inertia Ix = 0.019 in⁴, with a plastic modulus Zx = 0.0686 in³.
