Seek 3A45 degree elbow height calculation formula

The elbow size formula for this topic has its own unique insights, the following experience, I hope you learn more.

1, 1.5 times the elbow center height = through diameter * 1.524, in fact, is the through diameter * multiplier, the results of the decimal point behind the number of rounded to the nearest whole number, such as the through diameter of 219 is 200, the center of the height of the 200 * 1.524 = 304.8, take 305; and such as 114 of the through diameter of 100, the center of the height of the 100 * 1.524 = 152.4, take 152.4, take 152.

(Applicable to DN100 and above the radius of curvature of the elbow algorithm to facilitate quick calculation).

2, poke high = center height + radius of the elbow, such as 1.5 times the diameter of 219 elbow poke high = 305 + 219 / 2 = 305 + 109.5 = 414.5

3, the outer arc length = (center height + radius) * 3.14 * 2/360 * degrees, that is, (poke high) * 3.14 * 2/360 * degrees, from which you can deduce the length of the outer arc of 90 degrees. Degree elbow of the outer arc length = poke high * 3.14 / 2

4, the inner arc length = (center high - radius) * 3.14 * 2/360 * degrees

5, the length of the elbow of the material = elbow center high * 3.14/2 * elbow OD / diameter of the pipe + (pipe wall thickness * 3) + machining allowances, such as 180 * 8 of the pipe material, push 273 elbow, the elbow can be calculated using the above formula, and the elbow can be calculated using the above formula, and the elbow can be calculated using the above formula, the length of the elbow can be calculated using the above formula, the length of the elbow can be calculated using the above formula, the length of the elbow can be calculated using the above formula, the length of the elbow can be calculated using the above formula. The above formula can be calculated, the length of the material = 381 * 1.57 * 273/180 + 24 = 931.22mm + processing allowance
