What formula is used to calculate nickel pipe weight?

The formula is: Weight = (π ÷ 4) × (OD² − ID²) × Length × Density. OD is the outer diameter in meters, ID is the inner diameter (OD minus 2× wall thickness) in meters. Multiplying the hollow-cylinder volume (m³) by the nickel alloy density (kg/m³) gives weight in kilograms.

What is the density of pure nickel?

Pure nickel (Nickel 200 / Nickel 201) has a density of 8908 kg/m³ (0.3219 lb/in³). Alloyed grades such as Inconel 625 (8440 kg/m³) or Hastelloy C276 (8890 kg/m³) have slightly different densities, which this calculator accounts for.

What is the difference between outer diameter and wall thickness?

Outer diameter (OD) is the total outside measurement of the pipe. Wall thickness is the radial thickness of the pipe wall. Inner diameter (ID) = OD − 2 × wall thickness. The calculator warns you if the wall thickness exceeds half the OD, which would be physically impossible.

Which nickel alloys are supported?

Nickel 200 (8908 kg/m³), Nickel 201 (8908 kg/m³), Monel 400 (8800 kg/m³), Inconel 625 (8440 kg/m³), Inconel 718 (8220 kg/m³), Hastelloy C276 (8890 kg/m³), and Incoloy 825 (8140 kg/m³). A custom density option is also available.

Can I calculate total weight for a batch of pipes?

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

What units are supported?

Diameter and wall thickness accept mm, cm, or inches. Length accepts meters, mm, feet, or inches. All values are converted to meters internally before the calculation is performed.

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).
