NOTE 2—For testing methods not specifically covered in this specification, reference can be made to Test Methods and Definitions A 370A370, with
particular reference to Annex A2 on Steel Tubular Products.
NOTE 3—A comprehensive listing of standardized pipe dimensions is contained in ANSI B 36.10.

1.2 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.
NOTE 4—The dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional terms as “nominal diameter”,
“size”,diameter,” “size,” and “nominal size”. size.”
1.3 The following precautionary caveat pertains specifically to Section 5 of this specification. 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.

3.1.2 Name of material (electric-fusion- (arc)-welded pipe),
3.1.3 Grade (Section 4),
3.1.4 Size (inside or outside diameter and nominal wall thickness),
3.1.5 Length (specified or random),
3.1.6 Specific straightness requirements (see 12.3),
3.1.7 End finish (Section 15),
3.1.8 Hydrostatic test pressure (Section 11),
3.1.9 ASTM designation, and
3.1.10 End use of material.
4. Material
4.1 The steel from which the pipe is made shall conform to Specifications A 283/A 283MA283/A283M, A 285/A
285MA285/A285M,A570A570/A570M,orA36/A36MA36/A36MortootherASTMspecificationsforequallysuitableweldable
material, as specified:. For purposes of marking and certification, when required, the pipe grade of material shall be established
by the A xxx plate specification designation and plate grade, when applicable.
5. Manufacture
5.1 The longitudinal edges of the steel shall be shaped to give the most satisfactory results by the particular welding process
employed.Thesteelshallthenbeproperlyformedandmaybetackedpreparatorytowelding.Theweldshallbemadebyautomatic
means (except tack welds) and shall be of reasonably uniform width and height for the entire length of the pipe. By agreement

5.2 All longitudinal seams, spiral seams, and shop girth seams shall be butt-welded.
6. Number of Production Weld Tests
6.1 One weld test specimen specified in Section 8 shall be made from each lot of 3000 ft (900 m) of pipe or fraction thereof
of each size and wall thickness.
6.2 If any test specimen shows defective machining or develops flaws not associated with the welding, it may be discarded and
another specimen substituted.
6.3 Each length of pipe shall be subjected to the hydrostatic test specified in Section 11, unless otherwise specified in 11.3.
7. Retests
7.1 If any specimen tested in accordance with Section 10 fails to meet the requirements, retests of two additional specimens
from the same lot of pipe shall be made, each of which shall meet the requirements specified. If any of the retests fail to conform

meet the requirements specified, or that pipe shall be rejected.
8. Test Specimens of Production Welds
8.1 The weld-test specimens for the reduced-section tension test shall be taken perpendicularly across the weld and from the
end of the pipe or, alternatively, from flat test pieces of material conforming to the requirements in the specifications used in the
manufacturer of the pipe. The alternative weld-test specimens shall be welded with the same procedure and by the same operator
and equipment, and in sequence with the welding of the longitudinal joints in the pipe. The test pieces shall have the weld
approximately in the middle of the specimen. The specimens shall be straightened cold, and shall be tested at room temperature.
8.2 Reduced-section tension-test specimens shall be prepared in accordance with Fig. number 21 of Test Methods and
Definitions A 370A370.
9. Qualification of Welding Procedure
9.1 The welding procedure shall be qualified in accordance with the American Welding Society Standard Qualification
Procedure orASME Section IX of the Boiler and Pressure Vessel Code as agreed to between the manufacturer and the purchaser
using the tests and test values specified in 9.2 and 9.3. Thicknesses less than ⁄8 in. (10 mm) shall be qualified for each wall
3 3 3
thickness of pipe manufactured. Thicknesses ⁄8 to ⁄4 in. (10 mm to 19.0 mm), inclusive, shall be qualified in ⁄8-in. (10-mm)

A134 – 96 (2005)
9.2 Two reduced-section tension specimens (transverse weld) made in accordance with Fig. number 21 of Test Methods and
DefinitionsA370A370, with the weld reinforcement removed, shall show a tensile strength not less than 100 % of the minimum
specified tensile strength of the base material used.
9.3 Two face-bend test specimens shall be prepared in accordance with Fig. number 2 (a) 2(a) of Test Methods and Definitions
A370A370 and shall withstand being bent 180° in a jig substantially in accordance with Fig. 30 of Test Methods and Definitions
A370A370. The bend test shall be acceptable if no cracks or other defects exceeding ⁄8 in. (3.2 mm) in any direction be present
in the weld metal or between the weld and the pipe metal after bending. Cracks that originate along the edges of the specimens
during testing and that are less than ⁄4 in. (6.3 mm) in any direction, shall not be considered.
10. Tensile Properties of Production Welds
10.1 Reduced-section tension test specimens required in Section 8, taken perpendicularly across the weld with the weld
reinforcement removed, shall show a tensile strength not less than 95 % of the specified minimum strength of the steel. At the
manufacturer’s option, the test may be made without removing the weld reinforcement, in which case the tensile strength shall b
