ASTM A252 steel piling pipe is a structural
pipe ideally suited for application in retaining walls, buildings and other
structures needing dependably, solid, quality made steel piling pipe as its
structure.
KING STEEL is one of the large
manufacturers for high quality ASTM A252 Structural Steel Pipes. ASME SA252
Specifications describes nominal (i.e. average) wall steel piles pipe of
cylindrical shape and applies to pipe piles in which the steel cylinder acts as
a permanent load carrying member or else as a shell to form case-in-place
concrete piles. Imperfect Surface exceeds 25% of the nominal wall in depth are
considered defects. Defects not exceeds 22.5% of the nominal wall in depth
shall be repaired by welding. Before welding, the defect shall be completely
removed.

Permissible Variations for ASTM 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 pipes shall not vary more than 15% over or under 5% the
weight specified. Each individual length shall be weighed separately.
Outside diameter: Shall not vary more than
plus or minus 1% from the diameter as specified.
