Steel Pipe Piles

Standard Sizes
In JIS specifications, the sizes and section properties of steel pipe piles are classified according to two types, as shown in Tables 1 and 2.
Generally speaking, it is most economical to use the outside diameter, the wall thickness, and the pile length best suited for specific design requirements. This is particularly true

with large-diameter, heavy-wall and long-length pipe piles. In actuality, however, other factors such as the manufacturing process, production capacity, and method of transport have to be taken into account. Therefore, it is desirable that the manufacturers be consulted for individual projects.

Formulas for Section and Properties and Weights are as follows:
Weight                                              W = 0.02466 t (D-t) kg/m
Cross Sectional Area of Steel        A = p . t. (D-t) x 10^-3 cm²
Moment of Inertia                            r = p /64 (D⁴ - d⁴) x 10^-4cm⁴
Section of Modulus                         Z = p /32 x (D⁴-d⁴) / D x 10^-3cm³
Radius of gyration                           i = Ö l / A    cm

where
D = outside diameter (mm)
t = wall thickness (mm)
d = inside diameter (mm)
