Elbow volume (the volume / 1000000 * material density values, is the weight, unit: kg/a)

1) torus volume formula = PI * r * r * 2 * PI * r r - ring body section radius r - ring into the center of the ring body body section center distance, the radius of curvature

2) hollow torus volume formula = (r * r - PI PI * * r '* r) * 2 * PI * r r' - ring body section within a radius of 180 degrees, 90 degrees, 45 degrees Angle is equal to 1/2 respectively, 1/4, 1/8 hollow torus

= 3), 90 - degree bend volume formula (r * r - PI PI * * r '* r) / 4 * 2 * PI * r = 2 * (D/D / 2 - (D - 2 * S) / 2 * (D - 2 * S) / 2) / 2 * PI * PI * r = (D - S) PI / 2 * PI * * S * r, D - bend diameter in mm S - elbow wall thickness, unit mm r - bend section center to the torus center distance, the radius of curvature, in mm

For example,

Such as 159 * 4 not 304 stainless steel 304 degree Angle, diameter is 159 mm, wall thickness of 4 mm to check the standard GB/T12459, long radius elbows curvature radius of 229 mm, short radius elbows curvature radius of 152 mm, 304 stainless steel elbow material density value is 7.93 g/cm ^ 3 g/mm ^ 3 = 7.93/1000 = 7.93/1000 Kg/mm ^ 3

The weight of the 90 - degree Angle formula = (D - S) * S * R * PI / 2 * PI * 7.93/1000000 Kg

(1). 304 stainless steel material, the weight of 90 degrees of the long radius elbow = (159-4) * 4 * 229 * 3.14 * 3.14/2 * 7.93/1000000 = 5.55 Kg

(2). 304 stainless steel material, the weight of 90 degrees of short radius elbow = (159-4) * 4 * 152 * 3.14 * 3.14/2 * 7.93/1000000 = 3.69 Kg
