Pipe6XS 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.

Pipe6XS has a 6 5/8 in. outside diameter and a 7/16 in. nominal wall.

Also known as NPS 6 pipe (6 in. nominal), Schedule 80 (XS) wall.

At 28.6 lb per foot it is one of the 3 Pipe6 sizes, which run from 19 to 53.2 lb/ft.

For strong-axis bending its section modulus is Sx = 11.6 in³ and its moment of inertia Ix = 38.3 in⁴, with a plastic modulus Zx = 15.6 in³.
