The simple formula for calculating the weight of ordinary carbon steel pipe is (outside diameter-wall thickness) × wall thickness mm×0.02466× length m. As for how this simple formula is derived, du is simplified according to the volume x density of steel pipe, so I will not explain it in detail here.
Example: steel pipe 1 14mm (outer diameter) ×4mm (wall thickness) ×6m (length), calculated as (1 14-4)×4.
Extended data:
Weight of steel pipe =0.25×π× (square of outer diameter-square of inner diameter )× l× specific gravity of steel, where π= 3. 14 L= length of steel pipe?
The specific gravity of steel is 7.8, so the weight of steel pipe =0.25×3. 14× (square of outer diameter-square of inner diameter )× ×L×7.8 * If the dimension unit is meters (m), the calculated weight result is kilograms (Kg).
The density of steel is 7.85g/cm3.
