51 steel pipe network to provide: the theoretical weight of the seamless steel pipe

The actual component of the seamless steel tube steel is calculated as the actual component by calculating the nominal size and density (previously called specific gravity) of the steel material. This has an indirect relationship with the allowable deflection of the length dimension, cross-sectional area and size of the steel. Because of the allowable bias in the manufacturing history of steel, the actual component and the actual component of the formula calculation have a positive balance, which is only used as a reference for the budget.
Seamless Steel Pipe Size and Allowable Deviation Deviation Standard Deviation Allowable D1 ±1.5%, Minimum ±0.75 mm
D2 ±1.0%. Minimum ±0.50 mm
D3 ±0.75%. Minimum ±0.30 mm
D4 ± 0.50%. Minimum ±0.10 mm
