How to Calculation Geometric Size of Elbow
The elbow is a connection pipe fitting used to connect pipes and change the direction of the pipe in installation, so that the pipe can be turned at 90°, 45°, 180° and various degrees. Bending radius ≤ 1.5 times of pipe diameter is elbow, bending radius> 1.5 times of pipe diameter is bend. Technical requirements for the produce elbows: It is required to control the radius of curvature. For example, if the radius length is 1.5D, then the radius of curvature must be within the required tolerance range. Since most of these pipe fittings are used for welding, in order to improve the welding quality, the ends are beveled, with a certain angle and a certain side. This requirement is very strict. For the welding requirement, the steel material of the connected pipe should be the same. 1. 1.5 times the center height of the elbow A = diameter * 1.524, which is the diameter D * multiple, and the result will be the number after the decimal point is rounded to the nearest whole...
