I believe you will find what you need in EN 583-2. Rgds, Norman

Re: Refracted Angles Try this formula:

Sin of Angle 1 = Sin of Angle 2 * ID/OD

This calculates the required refracted angle (Sin Angle 1) at the inside diamter (ID) of the component based upon the ID/OD ratio.

Sin of Angle 2 is the desired angle, i.e., 45 degrees

ID is the inside diameter dimenison

OD is the Outside Diameter dimension
