Specifications: diameter: 320 to 127 mm thickness: 0.4 to 12.7 mm Length: 6 m above, and, in accordance with customer demand, supply and other specifications of steel pipe

Carbon Steel Elbow weight formula


Carbon Steel Elbow weight formula
Ring volume = 2X3.14X3.14 (r ^ 2) R
  r - radius circle
  R - radius of gyration of the ring
  Hollow tube ring volume = 2X3.14X3.14 ((r ^ 2) - (r '^ 2)) R
  r'- circle radius of the inner circle
  90,60,45 degree elbow (elbow), respectively corresponding to the volume of the hollow tube ring volume of 1/4, 1/6, 1/8.
  The density of steel engineering calculations by weight 7.85 kg / dm, density X volume = weight (mass).
1,180 ° Elbow calculated according to Table 2-fold, 45 ° at 1/2 calculation;
  2, R1.0DN elbow weight according to Table 2/3 of the calculation;
  3, the wall thickness is not listed in the table weight, preferably with similar two weight averages;
  4,90 ° elbow formula; 0.0387 * S (DS) R/1000 where S = thickness mm D = diameter mm R = bending radius mm
 Carbon Steel Elbow
