Formulas for calculating LSAW steel pipe theoretical weight

1. The theoretical weight should be calculated as follows:

M=0.0246615(D-T)T

In the formula: 

M-steel pipe unit length weight

Kg/M accurate to two decimal places, such as 0.01Kg

D——Nominal outer diameter of steel pipe mm

T——Nominal wall thickness of steel pipe mm

2. Steel pipes within the scope of this standard shall be delivered according to the theoretical weight, and also can use the actual weight according to by agreement.
