Astm A252 Pipe Pile

Changsha China
Categories: Oil and Gas / China

ASTM A252 is the standard specification for steel pipe piles for friction and load-bearing deep foundation applications. 

American Standard ASTM A252 is pipe piling material standard that has been widely used in constructions and structural buildings. A252 specification includes three grades (1, 2, and 3), Grade 3 pipe piling material is the most used option.

ASTM A252 definitions

ASTM A252 is the standard specification for welded and seamless steel pipe piles. It covers the nominal wall thickness of cylinder shape steel pipe, rectangular pipe is not included. These round pipes are used for piling purposes, playing as a permanent role of load carrying and bearing the pressure. Further more, to act as a tank shell to fill with the concrete piles at sight of the project.

This standard stated the values units in inch-pound (also could be translated to SI units), which provides the reference A252 pipe data to engineer or designer, for a strength base of the constructions.

Chemical composition and mechanical properties of ASTM A252 pipe

The standard has a limit for element P (phosphorous) maximum 0.050%, since P will make steel fragile, and most important is not good for welding performances. ASTM A252 standard specifications only defines the conten of phosphorous, other elements accord with general carbon steel material.
