Technical Data for A252

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.

Application:

• Buildings
• Retaining walls
• Different structures that need a tough base

A.The above table gives the calculated minimum elongation values fo vanious nominal wall thicknesses.Where the specified nominal wall thicknes is intermediate to those shown abovethe minimum elongation value shal be determined as follows:

	Grade	1	E=48t+15.00 [E=1.90t+15.00]
	Grade	2	E=401+12.50[E=1.56t+12.50]
	Grade	3	E=32t+10.00[E=1.25t+10.00]
Where:
E=elongation in 2in.,%,and
t =specified nominal wall thickness,in.[mm].

Testing Requirements for A252 steel pipe piling

It includes:

Material analysis

Heat Analysis: Limits to elements P, and heat result shall be reported in MTC to customer.
Tensile requirements: Values shall be complied to the above tensile strength and yield strength. It shall be noted that if got a vague yield point, then to test yield strength corresponding to a permanent offset of 0.2% of the gage length of the sample specimen, or to test a total extension of 0.5% of the gage length under load.

Weight and dimension tolerances

Pipe pile weights per units (Feet, meter or lengths)
Tolerance allowed: A252 pipe pile weight shall be in +15% or -5% of theoretic weight.

OD tolerances at +/-1%

wall thickness +/- 12%.
Lengths: As specified SRL, DRL, or fixed length 20 ft or 40 ft and customized.

Different than other pipelines

Hydrostatic test is not specified in ASTM A252 pipe specification, as normally piling pipe is filling with cement and concrete and forming, not for liquid transmission, so hydrotest is not required.

Different test methods for seamless and welded pipe piles

Seamless, welded, (Longitudinal or helical welded) test methods are different. Check ASTM A252 pipe standard specification for more details. But all of these types are tested in a room temperature.
