The American Society for Testing and Materials specification ASTM A252 is the standard for welded and seamless steel pipe piles. This specification covers nominal (average) wall steel pipe piles of cylindrical shape, and it 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.

Testing requirements for seamless and welded A252 steel piling pipe
Tensile Test: Either longitudinal or transverse at option of manufacturer.
Hydrostatic Testing: Not specified.
Number of Tests: One tensile test per 200 lengths.
Permissible Variations for A252 steel piling pipe
Wall thickness: Not more than 12.5% under the nominal wall thickness specified.
Weights per foot: The weight of any individual length of pipe shall not vary more than 15% over or 5% under the weight specified. Each individual length shall be weighed separately.
Outside diameter: Shall not vary more than plus or minus 1% from the diameter specified.
Surface imperfections exceeding 25% of the nominal wall in depth are considered defects. Defects not exceeding 22.5% of the nominal wall in depth may be repaired by welding. Before welding, the defect shall be completely removed.
Lengths of A252 steel piling pipe
ASTM A252 steel piling pipe may be ordered in single or double random lengths or in uniform lengths.
Single random – 16’ – 25’ inclusive
Double random – Over 25’ with a minimum average of 35’
Uniform – Plus or minus 1” on length specified
