Cobalt Pipe
Weight Calculation
How is the weight of Cobalt Pipe calculated?
Pipe weight (kg/m) = (outside diameter − wall thickness) × wall thickness × π × density / 1000. One metre of Ø48.3 × 3 mm Cobalt Pipe weighs about 3.800 kg.
What is the density of Cobalt?
The density of Cobalt is taken as 8.9 g/cm³ (8,900 kg/m³).
