Title
Standard Specification for Hot-Formed Welded and Seamless Carbon Steel Structural Tubing
ASTM International
Publication Date:
Mar 1, 2007
Scope:
This specification covers black and hot-dipped galvanized
hot-formed welded and seamless carbon steel square, round,
rectangular, or special shape structural tubing for welded,
riveted, or bolted construction of bridges and buildings, and for
general structural purposes.
Square and rectangular tubing is furnished in sizes 1 to 32 in.
(25.4 to 813 mm) across flat sides with wall thicknesses 0.095 to
3.00 in. (2.41 to 76 mm), dependent upon size; round tubing is
furnished in NPS ½ to NPS 24 (see Note 1) inclusive, with nominal
(average) wall thicknesses 0.109 to 1.000 in. (2.77 to 25.40 mm),
dependent upon size. Special shape tubing and tubing with other
dimensions is permitted to be furnished, provided that such tubing
complies with all other requirements of this specification.
NOTE 1—The dimensionless designator NPS (nominal pipe size) has
been substituted in this standard for such traditional terms as
"nominal diameter," "size," and "nominal size."
This specification covers the following grades:
Grade A — 36 000 psi (250 MPa) min yield strength.
Grade B — 50 000 psi (345 MPa) min yield strength.
An optional supplementary requirement is provided for Grade B
and, when desired, shall be so stated on the order.
The following precautionary statement pertains only to the test
method portion of this specification: This standard does not
purport to address all the safety concerns, if any, associated with
its use. It is the responsibility of the user of this standard to
establish appropriate safety and health practices and determine the
applicability of regulatory limitations prior to use.
The values stated in inch-pound units are to be regarded as
standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and
are not considered standard.
The text of this specification contains notes and footnotes that
provide explanatory material. Such notes and
footnotes, excluding those in tables and figures, do not
contain any mandatory requirements.
