Pipe3STD 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.
Pipe3STD has a 3 1/2 in. outside diameter and a 3/16 in. nominal wall.
Also known as NPS 3 pipe (3 in. nominal), Schedule 40 (STD) wall.
At 7.58 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 = 1.63 in³ and its moment of inertia Ix = 2.85 in⁴, with a plastic modulus Zx = 2.19 in³.
