The weight of pipes can be calculated very easily. All you have to do is insert the respective tightness factor for the individual materials into the formula below.
Weight = ( D - T ) x T x 0.02504
D = outer diameter
T = wall thickness
Conversion factor for stainless steel = 0.02504
For all other alloys, divide the result by 8 and then multiply by the conversion factor for each alloy using the table below.
When calculating the weight of inch dimensions, certain measurements (fractions) must be converted to decimal inches. For a more accurate calculation, it is also important to know the tolerances for diameter and wall thickness, which are defined in the manufacturing specification. Please contact us for further details.
Please refer to the chart below for the conversion factors of some common materials:
| Material | kg/dm3 | Material | kg/dm3 |
| Stainless Steel | 7.90 | C4 | 8.64 |
| (Super) duplex | 7.90 | C22 | 8.70 |
| 200 | 8.89 | C276 | 8.88 |
| 201 | 8.89 | B2 | 9.22 |
| 400 | 8.83 | B3 | 9.22 |
| 600 | 8.42 | Titanium | 4.51 |
| 601 | 8.06 | Zirconium | 6.50 |
| 625 | 8.44 | Copper | 8.92 |
| 800 | 7.94 | Aluminium | 2.70 |
| 800H | 7.94 | Tungsten | 8.52 |
| 800HT | 7.94 | Brass | 8.47 |
