Description

ASTM A252 / A252M – 19 Welded and Seamless Steel Pipe Piles

ASTM A252 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. Pipe piles are produced as both welded and seamless products.
