Shaft screw ground lead galvanized foundation pile
Foundation piles also called the helical piers,screw piles.
As we all know,the foundation pile using is that put the low carbon structural steel and low alloy steel strip according to certain
Angle of helix Angle (called molding) rolled into a tube billet, then foundation piles seam welding made up,
foundation piles can use a narrow strip in the production of large diameter steel pipe.
The foundation pile is mainly used for oil and gas pipeline, and
its specification is indicated by the outer diameter * wall thickness.
The foundation pile has single side welding and double - face welding.
The screw ground shall ensure that the water pressure test,
the tensile strength and the cold bending performance of the weld are in accordance with the regulations.
