What Is a Tube Weight Calculator?
A Tube Weight Calculator is an online tool designed to quickly calculate the weight of hollow tubes or pipes. Instead of using complicated formulas, you simply:
- Enter the outer diameter (mm)
- Enter the inner diameter (mm)
- Add the tube length (m)
- Select the material type (steel, aluminum, copper, stainless steel, titanium, etc.)
The calculator then provides the weight in kilograms (kg).
This makes it useful for fabrication shops, construction engineers, students, and suppliers who need fast, accurate results.
Formula Behind the Calculator
The tool is based on the cross-sectional area method.
Step 1: Cross-sectional area of tube
Area=π4×(OD2−ID2)\text{Area} = \frac{\pi}{4} \times (OD^2 - ID^2)
Where:
- ODOD = Outer Diameter (in meters)
- IDID = Inner Diameter (in meters)
Step 2: Volume of tube
Volume=Area×Length\text{Volume} = \text{Area} \times \text{Length}
Step 3: Tube weight
Weight=Volume×Density of Material\text{Weight} = \text{Volume} \times \text{Density of Material}
Each material has a different density, for example:
- Steel = 7850 kg/m³
- Aluminum = 2700 kg/m³
- Copper = 8960 kg/m³
- Stainless Steel = 8000 kg/m³
- Titanium = 4500 kg/m³
How to Use the Tube Weight Calculator
Using the tool is straightforward:
- Enter Outer Diameter – in millimeters (mm).
- Enter Inner Diameter – also in mm.
- Enter Length – in meters (m).
- Select Material – steel, aluminum, copper, stainless steel, or titanium.
- Click Calculate – The result will instantly show the tube’s weight in kilograms.
- Reset Anytime – Start fresh with new values.
Example Calculation
Let’s calculate the weight of a steel tube with:
- Outer Diameter (OD) = 100 mm
- Inner Diameter (ID) = 90 mm
- Length = 6 m
Step 1: Convert to meters
OD = 0.1 m, ID = 0.09 m
Step 2: Cross-sectional area
Area=π4×(0.12−0.092)=0.00149 m2\text{Area} = \frac{\pi}{4} \times (0.1^2 - 0.09^2) = 0.00149 \, m^2
Step 3: Volume
Volume=0.00149×6=0.00894 m3\text{Volume} = 0.00149 \times 6 = 0.00894 \, m^3
Step 4: Weight
Weight=0.00894×7850=70.2 kg\text{Weight} = 0.00894 \times 7850 = 70.2 \, kg
The tube weighs 70.2 kilograms.
