Metleader is a supplier and manufacturer of 60 degree pipe elbow. The 60 degree pipe elbow manufactured adapting top quality raw materials. The 60 degree pipe elbows are applied for connecting pipes widely used in types of chemicals, power plant, oil & gas industry, ship building, petroleum industry etc. How to calculate the long radius of 60 degree elbow?
1.5 times the height of the elbow center = the diameter *1.524, in fact, the diameter * multiple, the number after the decimal point of the result will be rounded to the whole number, such as the diameter of 219 is 200, the center height is 200 * 1.524 = 304.8 Take 305; if the path of 114 is 100, the center height is 100*1.524=152.4, take 152. (The algorithm for radius of curvature of DN100 and above is convenient and quick to calculate).
2, poke height = center height + radius of the elbow, such as 1.5 times the diameter of the 219 elbow stamp = 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 calculate the outer arc length of the 90 degree elbow = stamp High *3.14/2.
4. Inner arc length = (center height - radius) * 3.14 * 2 / 360 * degrees.
5, the length of the elbow blank = the height of the elbow center * 3.14 / 2 * outer diameter of the elbow / pipe diameter + (pipe wall thickness * 3) + machining allowance, such as 180 * 8 pipe cutting, push The elbow of 273 can be calculated by the above formula, and the length of the blank is =381*1.57*273/180+24=931.22mm+ machining allowance.
