ASTM A 381 Document Information:
Title
Standard Specification for Metal-Arc-Welded Steel Pipe for Use with High-Pressure Transmission Systems
ASTM International
Publication Date:
Sep 10, 1996
Scope:
This specification covers straight seam, double-submerged-arc-welded
steel pipe (Note 1) suitable
for high-pressure service, 16 in. (406 mm) and larger in outside
diameter, with wall thicknesses
from 5/16 to 1½ in. (7.9 to 38 mm). The pipe is intended for
fabrication of fittings and
accessories for compressor or pump-station piping. Pipe ordered to
this specification shall be
suitable for bending, flanging (vastoning), corrugating, and similar
operations.
NOTE 1 - A comprehensive listing of standardized pipe dimensions is
contained in ANSI B36.10.
NOTE 2 - The term "double welded" is commonly used in the gas and oil
transmission industry, for
which this pipe is primarily intended, to indicate welding with at
least two weld passes, of which
one is on the outside of the pipe and one on the inside. For some
sizes of the pipe covered by this
specification, it becomes expedient to use manual welding, in which
case the provisions of Note 3
shall be followed.
Nine classes of pipe, based on minimum yield point requirements, are
covered as indicated in Table
1.
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 following caveat applies to the test methods portion, Sections 9
and 10, only. This standard
does not purport to address all of 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.
