Standard pipe, extra strong (x-strong) pipe and double-extra strong (xx-strong) pipe sizes, dimensions and section properties are given in the following structural steel pipe chart per
Steel Construction Manual.
Structural pipe is a round hollow section and generally used as structural columns. Steel pipe is produced in three different strength categories: standard, x-strong and xx-strong. Steel pipe wall thickness determines the pipe category.
Steel pipes are manufactured to meet ASTM A53 grade B (Fy = 35 ksi) and proper designations are Std., x-strong or xx-strong. Pipes up to and including NPS 12 are designated by the term "Pipe", nominal diameter (in.) and weight class (std., x-strong and xx-strong). Pipe
4 Std. is a pipe with a 4-in nominal diameter and a 0.237-in wall thickness. Pipes which do not correspond to the forgoing weight classes are designated by the term "Pipe
", outside diameter (in.), and wall thickness (in.) (Ex: Pipe 16.000x0.375).
Pipe section properties which are given by following calculator are moment of inertia, elastic section modulus, radius of gyration, torsional moment of inertia and plastic section modulus.
