A252 Comparative Specifications

ASTM Specification A252 describes 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 case-in-place concrete piles.

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.
