Steel Pipe · AISC Shapes Database v15.0 · United States
Pipe5XS is a steel pipe section 141.3 mm in outside diameter with a 8.9 mm wall, weighing 31.0 kg/m. The dimensions below are the published AISC Shapes Database v15.0 values; the drawing is generated from them.
Pipe sections are round tubes to ASTM A53 dimensions, tabulated by AISC alongside the HSS range for columns, braces and handrails.

Derived section properties
Integrated analytically from the exact circular tube. For Pipe5XS the computed area agrees with the published value to 0.28% and Ix to 0.03%. Where a value is also published, the published one above is the one to quote.
AISC tabulates hollow-section properties on the design wall (tdes = 0.93 tnom, per AISC 360), while the published mass reflects the nominal wall — which is why mass and area here differ by about 7% by convention, on every AISC hollow section.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 114,915 mm³ |
| Elastic modulus, Sy | 114,915 mm³ |
| Plastic modulus, Zx | 155,639 mm³ |
| Plastic modulus, Zy | 155,639 mm³ |
| Radius of gyration, rx | 46.9 mm |
| Radius of gyration, ry | 46.9 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
