Formula = (D - T) × T × 0.02491
Outside Diameter = D (mm)
Wall Thickness = T (mm)
For example 88.9×3.05mm
(88.9 - 3.05)×3.05×0.02491 = 6.523kg/m
Stainless Steel Oval Tubing, Stainless Steel Elliptical Tube Theoretical Weight Calculator
First we need to convert the elliptical tube into a round tube to get the outer diameter of the steel tube.
Oval / Elliptical Circumference = 2× 3.1415 × b + 4 × (a - b)
a = the long semi-axis (half of the long axis)
b = the short semi-axis (half of the short axis)
OD of Oval/Elliptical Tubing = Oval / Elliptical Circumference/3.1415
