(Specification)Standard Specification for Welded and Seamless Steel Pipe Piles
Standard Specification for Welded and Seamless Steel Pipe Piles
ABSTRACT
This specification covers nominal wall cylindrical steel pipe piles in which the steel cylinder acts as a permanent load-carrying member or as a shell to form cast-in-place concrete piles. Each welded pile shall be made by seamless, electric resistance welding, flash welding or fusion welding with longitudinal, helical-butt, or helical-lap seams. This specification also deals with material tensile requirements, minimum elongation values and common size and weights per unit length values.
SCOPE
1.1 This specification covers nominal (average) wall steel pipe piles of cylindrical shape and applies to pipe piles in which the steel cylinder acts as a permanent load-carrying member, or as a shell to form cast-in-place concrete piles.
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.
1.3 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.
1.4 The following precautionary caveat pertains only to the test method portion, Section 16 of this specification. This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

9.2 It shall be permissible for the purchaser to make product analyses using samples from lots of pipe piles as follows:
A252 − 10 (2018)
Pipe Size Outside Number of Samples and Size of Lot
Diameter, in. (mm)
Under 14 (355.6) 2 from 200 pipe or fraction thereof
14 to 36, incl (355.6 to 914) 2 from 100 pipe or fraction thereof
14 to 36, incl (355.6 to 914) 2 from 100 pipe or fraction thereof
Over 36 (914) 2 from 3000 ft (914 m) or fraction thereof
The product analyses shall conform to the requirement in 7.1.
9.3 If the chemical compositions of both of the samples representing a lot fail to conform to the specified requirement, the lot
shall be rejected or analyses of four additional samples selected from the lot shall be made, and each shall conform to the specified
requirement. If the chemical composition of only one of the samples representing a lot fails to conform to the specified
requirement, the lot shall be rejected or analyses of two additional samples selected from the lot shall be made, and each shall
conform to the specified requirement.
10. Tensile Requirements
10.1 The material shall conform to the requirements as to tensile properties prescribed in Tables 1 and 2.
10.2 The yield point shall be determined by the drop of the beam, by the halt in the gage of the testing machine, by the use of
dividers, or by other approved methods. When a definite yield point is not exhibited, the yield strength corresponding to a
permanent offset of 0.2 % of the gage length of the specimen, or to a total extension of 0.5 % of the gage length under load shall
be determined.
11. Weights Per Unit Length
11.1 The weights per unit length for various sizes of pipe piles are listed in Table 3.
11.2 For pipe pile sizes not listed in Table 3, the weight per unit length shall be calculated as follows:
W 5 10.69 D 2 t t (1)
~ !
where:
W = weight per unit length, lb/ft,
D = specified outside diameter, in., and
t = specified nominal wall thickness, in.
12. Permissible Variations in Weights and Dimensions
12.1 Weight—Each length of pipe pile shall be weighed separately and its weight shall not vary more than 15 % over or 5 %
under its theoretical weight, calculated using its length and its weight per unit length (see Section 11).
12.2 Outside Diameter—The outside diameter of pipe piles shall not vary more than 61 % from the specified outside diameter.
12.3 Wall Thickness—The wall thickness at any point shall not be more than 12.5 % under the specified nominal wall thickness.
NOTE 2—The minimum permissible wall thickness on inspection is shown in Table X1.1 (see Appendix) for various nominal wall thicknesses.
13. Lengths
13.1 Pipe piles shall be furnished in single random lengths, double random lengths, or in uniform lengths as specified in the
purchase order, in accordance with the following limits:
Single random lengths 16 to 25 ft (4.88 to 7.62 mm), incl
Double random lengths over 25 ft (7.62 m) with a minimum average
of 35 ft (10.67 m)
Uniform lengths length as specified with a permissible
variation of ±1 in.
13.2 Lengths that have been spliced at the mill by welding shall be acceptable as the equivalent of unspliced lengths provided
tension test specimens cut from sample splices conform to the tensile strength requirements prescribed in Tables 1 and 2. The
welding bead shall not be removed for this test. Such specimens shall be made in accordance with the provisions specified in
Sections 16 – 18.
14. Workmanship, Finish, and Appearance
14.1 The finished pipe piles shall be reasonably straight and shall not contain imperfections in such number or of such character
as to render the pipe unsuitable for pipe piles.
14.2 Surface imperfections having a depth not in excess of 25 % of the specified nominal wall thickness shall be acceptable.
It shall be permissible to establish the depth of such imperfections by grinding or filing.
14.3 Surface imperfections having a depth in excess of 25 % of the specified nominal wall thickness shall be considered to be
defects. It shall be permissible for defects not deeper than 33 ⁄3 % of the specified nominal wall thickness to be repaired by welding,
provided that the defect is completely removed prior to welding.
A252 − 10 (2018)
15. Ends
15.1 Pipe piles shall be furnished with plain ends. Unless otherwise specified, pipe piles shall have either flame–cut or
machine–cut ends, with the burrs at the ends removed. Where ends are specified to be beveled, they shall be beveled to an angle
of 30 +5, −0°, measured from a line drawn perpendicular to the axis of the pipe pile.
16. Number of Tests
16.1 One tension test shall be made on one length or fraction thereof of each size, or one piece of skelp representing each lot
of 200 lengths or fraction thereof of each size.
16.2 A retest shall be allowed if the percentage of elongation of any test tension specimen is less than that prescribed in Tables
1 and 2 and any part of the fracture is more than ⁄4 in. (19 mm) from the center of the gage length for test specimens having a
2–in. (50 mm) gage length, or is outside of the middle third of the gage length for test specimens having an 8–in. (200 mm) gage
length, as indicated by scribe scratches marked on the specimen before testing. A retest shall also be allowed if any part of the
fracture is in an inside or outside surface imperfection.
16.3 It shall be permissible to discard any test specimen that shows defective machining or develops imperfections and
substitute another test specimen.
17. Retests
17.1 If the results of the tension test representing any lot fail to conform to the applicable requirements prescribed in Tables 1
and 2, the lot shall be rejected or retested using two additional lengths from the lot, with each such test being required to conform
to such specified requirements.
