Each welded pile shall be made by seamless, electric resistance welding, flash welding or fusion welding with longitudinal, helical-butt, or helical-lap seams.
Size and weights per unit length values.
This standard is issued under the fixed designation A 252; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon ( ュ) indicates an editorial change since the last revision or reapproval.
This specification has been approved for use by agencies of the Department of Defense. Consult the DoD Index of Specifications and Standards for specific year of issue which has been adopted by the Department of Defense.
1.1 This specification covers nominal (average)wall steel pipe piles of cylindrical shape and applies to pipe 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 the standard.
1.3 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 safery problems, if any, associated with its use. It is the responsi-bility of the user of this standard to establish applicability of regulatory limitations prior to use.
