From designation to geometry
Reading the Pipe26XS record
The Manual label Pipe26XS and electronic designation Pipe26SCH20 identify this pipe record. Nominal pipe size is an identifier: use the listed OD = 26 in and ID = 25.1 in for the reference envelope.
The record contains tnom = 0.5 in and tdes = 0.465 in. Keep the listed wall fields and schedule or weight-class identifier together; a pipe label alone does not establish the project material specification.
Ix = 2,950 in⁴ and Iy = 2,950 in⁴ refer to the database x- and y-axes. The two listed values are equal. Axis letters are labels, not a guarantee that x is always the larger axis. These are geometric properties, not allowable loads or complete member capacities.
Match the axis and dimension conventions to the figures in the AISC v16.0 workbook Readme. The profile above simplifies manufacturing geometry; its outline is not used to recalculate the published properties.
Worked quantity example
Nominal weight for Pipe26XS
Assume 3 pieces, each 20 ft (6.096 m) long. This is a hypothetical quantity example, not a stock-length or lifting recommendation.
| Quantity | Calculation | Nominal pounds | Kilogram equivalent |
|---|---|---|---|
| One 20 ft piece | 20 ft × 136 lb/ft | 2,720 lb | 1,233.771 kg |
| 3 pieces | 3 × 2,720 lb | 8,160 lb | 3,701.314 kg |
Conversion: 1 lb = 0.45359237 kg; displayed results are rounded. This multiplication excludes connection plates, bolts, weld metal, coatings, cutting allowances and actual material variation. Use the material takeoff for your own lengths and quantities.
Shape family context
What is a structural pipe section?
A PIPE entry describes a circular section using nominal pipe size and a schedule or weight class. Its outside diameter may remain constant across schedules while wall thickness, inside diameter, weight, and properties change.

Verify product specification, schedule, wall thickness, end preparation, connection fit, galvanizing or venting, and do not assume pipe and round HSS requirements are interchangeable.

Compare published reference values
Pipe26XS alongside nearby PIPE records
These records share the same nominal series, outside envelope or leg arrangement, depending on the family. Peers are ordered by absolute weight difference, then listed depth and designation. The table does not rank structural performance or approve a substitution.
| Record | Weight (lb/ft) | Outside diameter (in) | Area (in²) | Ix (in⁴) | Iy (in⁴) |
|---|---|---|---|---|---|
| Pipe26XS (this record) | 136 | 26 | 36.1 | 2,950 | 2,950 |
| Pipe26STD | 103 | 26 | 28.2 | 2,320 | 2,320 |
Relative to Pipe26XS, Pipe26STD changes nominal weight by -33 lb/ft, listed outside diameter by 0 in, and area by -7.9 in². At the same hypothetical 20 ft length, the nominal weight difference is -660 lb.

Data is derived from the AISC Shapes Database v16.0, consistent with the AISC Steel Construction Manual, 16th Edition, 1st Printing. AISC advises professional verification before use in a specific application. The downloadable DXF is a nominal reference profile and may simplify rolled fillets, flange tapers, angle radii, HSS corner radii, and other manufacturing geometry. Verify all dimensions and suitability before design, detailing, ordering, or fabrication.
