Standard of bending radius of elbow:
One tube and one mold, for a tube, no matter how many bends, regardless of the bending angle (should not be greater than 180 ℃), the bending radius should be uniform. Since one tube and one die, what is the appropriate bending radius for tubes with different diameters? The small bending radius depends on the material properties, the bending angle, the allowable thinning of the outside of the pipe wall after bending and the size of the inside wrinkle, and the size of the ellipse at the bend. Generally speaking, the small bending radius should not be less than 2 to 2.5 times the outer diameter of the pipe. For the duct of an airplane or an engine, since various pipes pass through the limited space inside and outside, the bending radius of the pipe should be smaller. The small bending radius can make the change of the shape of the tube flexible and adaptable. For large-diameter engines and large aircraft, if the piping arrangement is relatively loose, a slightly larger bending radius can be selected. Because a large bending radius is good for bending and forming, it is good for bending pipes.
