ASTM A252 definitions
ASTM A252 is the standard specification for welded 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.
What are ASTM A252 Grade 3 Steel Pipe Piles?
ASTM A252 steel is classified into three grades: Grade 1, Grade 2, and Grade 3. Grade 3 is the most commonly used steel for pipe pilingASTM A252 Grade 3 refers to high-strength steel pipes designed for use as piling material in various construction projects. This grade is specially designed to have high tensile and yield strengths.
