Description
ASTM A252 LSAW Steel Pipe

  ASTM A252 LSAW Steel Pipe 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.

Out Diameter 6.625"-16"
Wall Thickness 0.188" - 0.688" 

ASTM A252 standard for specification for welded and seamless steel pipe piles.

       This specification covers nominal wall cylindrical steel pipe piles in which the steel cylinder acts as a permanent load-carrying member or as a shell to form cast-in-place concrete piles. Each welded pile shall be made by seamless, electric resistance welding, flash welding or fusion welding with longitudinal, helical-butt, or helical-lap seams. This specification also deals with material tensile requirements, minimum elongation values and common size and weights per unit length values.

        The finished pipe piles shall be reasonably straight and shall not contain imperfections in such number or of such character as to render the pipe unsuitable for pipe piles.
Surface imperfections, the depth of which does not exceed 25% of the nominal wall thickness, shall be permitted. These may be explored by grinding or filing to establish the depth.Surface imperfections, the depth of which exceeds 25% of the nominal wall thickness shall be considered defects. Repair of defects by welding will be permitted when the depth of defect does not exceed 33 ½ % of the nominal wall thickness. Before welding the defect shall be completely removed.  

Testing Requirements for A252 steel pipe piling in seamless and welded

It includes:

Material analysis

Heat Analysis: Limits to elements P, and heat result shall be reported in MTC to customer.
Product Analysis: Test frequency shall be determined by the pipe diameter, where, under 14 inch 2 samples per 200 pieces, 14 to 36 inch 2 samples per 100 pieces, above 36 inch is 2 per 3000 ft.
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.
