How to Calculate Weight of Hollow Steel Pipes in KG (Kilograms)

In this civil engineering tutorial, you will learn How to Calculate Weight of Hollow Steel Pipes in KG (Kilograms) instantly for Billing Purposes. In this video, you will concretely learn to ascertain the weight of steel pipes.

First, understand the above drawing properly. A Hollow Steel Pipe is given whose Length is 3 meters. Its External diameter is 200 mm (0.2 m) and its Internal diameter is 190 mm (0.19 m).

The formula to calculate the Weight of Hollow Steel Pipe is as follows:

Weight of Hollow Steel Pipe = Volume of Hollow Steel Pipes x Density of Steel

So, now we have to find two-parameter, Volume and Density

Let us first calculate the Volume of Hollow Steel Pipe

The Volume of Hollow Steel Pipe

= [3.14 (0.2² – 0.19²) x 3] / 4

= 0.0091845 Cubic meter

We know, the Density of Steel is 7850 kg/m³

Weight of Hollow Steel Pipe

Volume of Hollow Steel Pipe x Density of Steel

= 0.0091845 x 7850

= 72.098 KG

In this simple way, we can find out the weight of the Hollow Steel pipe at the site for billing purposes.
