Pipe weight chart

Theoretical steel pipe weight

The theoretical weight of the steel pipe is calculated based on the nominal diameter and density of the steel pipe (in the past called the specific gravity), which is called the theoretical weight. This is directly related to the length, cross-sectional area, and size tolerance of the steel pipe. Due to the allowable deviation of the steel pipe in the manufacturing process, the theoretical weight calculated by the formula is different from the actual weight, so it is only used as a reference for estimation.

Pipe weight calculation formula

a. Round steel pipe  weight calculation formula:

kg/m = (Od-WT) * Wt * 0.02466, Od is the outer diameter, and Wt is the wall thickness

b. Square steel pipe weight calculation formula

kg/m = Wt (Oc – 4 Wt) * 0.00785, Oc is the outer circumference, and Wt is wall thickness. Square Oc=4 * a

c. Rectangular steel pipe weight calculation formula

Kg/m = (outer circumference – the sum of 4 sidewall thickness) * wall thickness * 0.00785

Kg/m = (Oc = 2 + 2 b) – the sum of wall thickness) * 0.00785 * wall thickness

Oc = 2a + 2b, a and b is the side length
