When buying steel pipes, have you ever faced this situation: You purchased 15 seamless pipes, expecting the weight to be 32 tons, but it turns out to be 35 tons after weighing.
This is actually caused by the wall thickness tolerance of the seamless pipe.
Let's look at the calculation formula for seamless steel pipe: seamless steel pipe weight per meter (kg) = (Outer diameter - Wall thickness) × Wall thickness × 0.02466.
For example, a 273*60 seamless steel pipe, outer diameter 273mm, wall thickness 60mm,
seamless steel pipe weight per meter (kg) =(273-60)×60× 0.02466
the weight per meter is 315.15kg.
