product introduction

ASTM A252 Steel Pipe Pile
Similar to H-piles, pipe piles of ASTM A252 carbon steel are also designed to transfer structural loads through the foundation to soils below. Where H-piles are typically classified as point bearing, pipe piles are most efficient as friction piles. Piling pipes have substantial surface area that interacts with the surrounding soil to provide great frictional load resistance.
Piling pipes are also used in conjunction with sheet piles to add lateral stiffness and bending resistance where loads exceed the capacity of sheet piles alone.
The steel pipe pile has the advantages of novel design and simple structure.lt is convenient to use and overlap during construction. When used in cofferdams, steel pipe piles can play the role of surrounding water, soil and sand. In addition, according to their different application, steel pipes can also be divided into pipes for pipe piling, pipes for machinery industry, pipes for petroleum geological drilling, etc.. Steel pipe piles are widely used in offshore engineering or marine engineering to create a solid foundation.

(3)Number of Tests: One tensile test per 200 lengths.

Permissible Variations for A252 steel piling pipe
(1)Wall thickness: Not more than 12.5% under the nominal wall thickness specified.
(2)Weights per foot: Each length of pipe pile shall be weighed separately and its weight shall not vary more than 15 % over or 5 % under its theoretical weight, calculated using its length and its weight per unit length.
(3)Outside diameter: Shall not vary more than plus or minus 1% from the diameter specified.

Lengths of A252 steel piling pipe
Pipe piles shall be furnished in single random lengths,double random lengths, or in uniform lengths as specified in the purchase order, in accordance with the following limits:
(1)Single random lengths: 16ft to 25ft inclusive (4.88 to 7.62 m)
