Galvanized steel pipes are trusted in many different systems. To buy suitable steel pipes, engineers often have to carefully measure and calculate the project and the type of pipe they intend to buy. Therefore, understanding how to calculate the volume of galvanized steel pipes is extremely necessary. The manual calculation will help a lot, especially in cases where the table to look up the volume and weight of galvanized steel pipes is not available. Read the article below to get this useful knowledge for yourself immediately!
How to calculate the volume of popular galvanized steel pipes
If you are looking for the formula to calculate the volume of galvanized round iron then below is the simple, easy, and most applied formula:
Weight (kg) = 0.003141 x T(mm) x {O.D(mm) – T(mm)
In there:
- T: Thickness
- L: Length
- O.D: Outside diameter
- Density = 7.85 g/cm3
At this point, to make it easier for everyone to imagine, we will make a few examples!
It can be seen that when estimating the volume and weight of galvanized steel pipes, we can calculate the estimated cost. This is extremely important, especially with large systems and projects.
*Note: The above calculation will sometimes have certain errors due to manufacturing tolerances. Therefore, to be sure, project owners should still weigh, measure, and check the actual volume of steel pipes.
Weight table of galvanized steel pipes
In addition to manual calculation through the formula we just provided, engineers also often use the available galvanized pipe weight table. This helps save maximum time while still getting results equivalent to manual calculation. However, as mentioned, in case you do not have the table below available, you can completely apply the formula we suggest. And you can rest assured because the results from these two methods are 99.99% the same.
