Standard Specification for Steel Tubes, Low-Carbon or High-Strength Low-Alloy, Tapered for Structural Use
|Publication Date:||1 March 2006|
|ICS Code (Steel pipes and tubes for specific use):||77.140.75|
This specification covers three grades of seam-welded, round, tapered steel tubes for structural use. GradesAand B are of low-carbon steel or high-strength low-alloy steel composition and Grade C is of weather-resistant steel composition.
This tubing is produced in welded sizes in a range of diameters from 2 3⁄8 to 30 in. [60 to 762 mm] inclusive. Wall thicknesses range from 0.1046 to 0.375 in. [2.66 to 9.53 mm]. Tapers are subject to agreement with the manufacturer.
The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used indepedently of the other. Combining values from the two systems may result in non-conformance with the standard.
A Summary of Changes section appears at the end of this standard.
