Theoretical Weight(kg/m) |
The weight per meter can be calculated by multiplying the product of the outer diameter (OD) and wall thickness (WT) of a material, both measured in millimeters, with a constant factor of 0.02507. |
Note:
OD is the specified outside diameter.
WT is the specified wall thickness
