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.

MECHANICAL PROPERTIES

ASTM A252 PIPE MATERIAL AND MANUFACTURING TYPES

Considering on the manufacturing types, ASTM A252 pipe piles could be made by seamless or welded processes.

Seamless pipe

Seamless pipe referred as hot rolled or cold drawn and thermal expanded seamless pipe.

Welded pipe
Welded pipe including ERW (electric resistance welded), flash welded, fusion welded or sub-merged welded SSAW or LSAW. Longitudinal or helical spiral welded.

Raw material making process
Raw material iron and steel could be made through the process of Open-hearth, Basic-oxygen, Electric-furnace.

REFERENCE STANDARDS FOR MAKING ASTM A252 PIPE

• ASTM A370 inspection methods and definitions for mechanical test of steel products.
• ASTM A751: Chemical analyze test methods.
• ASTM A941: Terminology for carbon, alloy and stainless steel.
• E29 practice for to use significant digits in test result to decide the conformance with specification.

PIPE APPLICATIONS
They have the expertise to maintain highly qualified materials are delivered to the customers that will assure high profits for them. The steel pipe pile provided by them is ASTM A252 pipe that has a cylindrical structure that carries the load and is ideally suited for many applications like
• Buildings
• Retaining walls
• Different structures that need a tough base
This ensures that the structure is solid, dependable with the highest quality that will guarantee the toughness which meets the international quality requirements.
