ASTM Specification A252 describes nominal (average) wall steel pipe stacks of cylindrical shape and uses to pipe piles in which the steel cylinder functions as a permanent load-carrying member or as a shell to form case-in-place concrete stacks.

Surface imperfections exceeding 25% of the nominal wall in depth are thought about flaws. Problems not going beyond 22.5% of the small wall in depth may be repaired by welding. Before welding, the flaw shall be completely eliminated.

ASTM A252 Gr 2 Mild Steel Piles are widely used for different projects and construction structure, just since it’s inexpensive however the steel pipe residential or commercial properties are likewise acceptable for jobs application. Moderate steel consists of approximately 0.05– 0.320% carbon making it flexible and ductile. Moderate steel piles has a fairly low tensile strength, but it is cheap and malleable; surface solidity can be increased through carburizing.
A252 Gr 2 Mild Steel Piles are generally for stacking pipelines and tubes purpose. Large size OD 34inch Steel Pipe Piles might be utilized in cross sea bridge, cross mountain bridge, developing foundation, buildings foundations application.
