Pipe4XXS 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.

Pipe4XXS has a 4 1/2 in. outside diameter and a 11/16 in. nominal wall.

Also known as NPS 4 pipe (4 in. nominal), double-extra strong (XXS) wall.

At 27.6 lb per foot it is the heaviest of the 3 Pipe4 sizes, which run from 10.8 to 27.6 lb/ft.

For strong-axis bending its section modulus is Sx = 6.53 in³ and its moment of inertia Ix = 14.7 in⁴, with a plastic modulus Zx = 9.5 in³.
