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.

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.
