Calculation formula of theoretical weight per meter of spiral welded pipe
Spiral welded pipe is divided into delivery by actual weight or delivery by theoretical weight
Actual weight - when delivered, the weight of the product is delivered according to the weighing (over-pound) weight;
Theoretical weight - When delivered, the weight of the product is calculated according to the nominal size of the steel. The calculation formula is as follows (for those who require delivery by theoretical weight, it should be indicated in the contract):
The formula for calculating the theoretical weight of the spiral welded pipe per meter: W=0.0246615(D-S)S+0.5
In the formula: W--theoretical weight per meter of spiral welded pipe, kg/m;
D--Nominal outer diameter of spiral welded pipe, mm;
S--Nominal wall thickness of spiral welded pipe, mm.
