Pipe3/4XS 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.

Pipe3/4XS has a 1 1/16 in. outside diameter and a 1/8 in. nominal wall.

Also known as NPS 3/4 pipe (3/4 in. nominal), Schedule 80 (XS) wall.

At 1.48 lb per foot it is one of the 7 Pipe3 sizes, which run from 1.13 to 18.6 lb/ft.

For strong-axis bending its section modulus is Sx = 0.0818 in³ and its moment of inertia Ix = 0.043 in⁴, with a plastic modulus Zx = 0.119 in³.
