ASTM A252 Grade 3 Steel Pipe is extensively used as steel stacking pipes, structure pipe stacks. A252 Grade 3 pipeline stack is produced under ASTM A252 Specification, which covers nominal (average) wall steel pipeline stacks of round shape and applies to a252 grade 3 pipeline piles in which the steel cylinder functions as a permanent load-carrying member, or as a shell to form cast-in-place concrete piles.
1. Material & Process of ASTM A252 Gr.3 steel piling pipes
