Calculation formula for theoretical weight of steel pipe：
Square tube:
【(Length+Width)*2/3.14-Wall thickness】*Wall thickness*0.02466*length*number
Example: such as 40*40*1.2*6 meters, 1000 pieces
The weight is: [(40+40)*2/3.14-1.2]*1.2*0.02466*6*1000
Round tube:
[(Outer diameter)-wall thickness] x wall thickness x0.02466*length*number
For example: such as 2 inches (outer diameter 59) * 1.2 * 6 meters, 1000 pieces
The weight is: (59-1.2)*1.2*0.02466*6*1000
Oval tube:
【(Length+Width)*2-24】/3.14-Wall thickness*Wall thickness*0.02466*length*number
Example: such as 30*60*1.2*6 meters, 1000 pieces
The weight is: [(30+60)*2-24]/3.14-1.2*1.2*0.02466*6*1000
How many meters per ton: 1000/weight per meter
How many sticks per ton: 1000/single stick weight
Price per piece: ton price*weight per piece/1000
