What formula is used to calculate titanium pipe weight?

The formula is: Weight = (π ÷ 4) × (OD² − ID²) × Length × Density. OD is the outer diameter, ID is the inner diameter (OD minus 2× wall thickness), all converted to meters. Multiplying the resulting volume (m³) by the titanium grade density (kg/m³) gives weight in kilograms.

What is the density of titanium?

Pure titanium (Grade 1 and Grade 2) has a density of approximately 4510 kg/m³. Alloyed grades vary slightly: Grade 5 (Ti-6Al-4V) is 4430 kg/m³, Grade 9 (Ti-3Al-2.5V) is 4480 kg/m³, Grade 12 is 4510 kg/m³, and Grade 23 (ELI) is 4430 kg/m³.

What is the difference between outer diameter and wall thickness?

Outer diameter (OD) is the total outside dimension of the pipe. Wall thickness is how thick the pipe wall is. The inner diameter (ID) equals OD minus 2× wall thickness. The calculator warns you if the wall thickness is too large for the given OD.

Which titanium grade is most common for pipes and tubes?

Grade 2 (commercially pure) is the most widely used for corrosion-resistant piping in chemical and marine applications. Grade 5 (Ti-6Al-4V) is preferred for aerospace and high-strength structural tubing. Grade 9 (Ti-3Al-2.5V) is popular for hydraulic tubing and bicycle frames.

Can I calculate total weight for multiple pipes?

Yes. Enter the number of pipes in the Quantity field and the calculator shows both the per-pipe weight and the total batch weight.

What units are supported?

Diameter and wall thickness can be entered in mm, cm, or inches. Length can be entered in meters, mm, feet, or inches. All values are converted to meters internally before calculation.

Formula Reference

W = (π / 4) × (OD² − ID²) × L × ρ

Where OD = outer diameter (m), ID = inner diameter = OD − 2×t (m), t = wall thickness, L = length (m), ρ = density (kg/m³), W = weight (kg).
