Lay out mitered pipe elbows. Enter pipe OD, the total turn angle, and how many pieces you want — get the cut angle and cutback for marking.
A mitered elbow is built from straight pipe sections cut at an angle. For a total turn angle split across a number of pieces:
Cut angle = Turn ÷ (2 × (Pieces − 1))
The two end pieces get one angled cut each; intermediate pieces get angled cuts on both ends (2× the cut angle across the piece). The cutback is how far the cut drops from a square line at the far side of the pipe:
Cutback = OD × tan(Cut angle)
Mark the cutback on the pipe, wrap a straight line between the high and low points, and cut. A 2-piece 90° elbow, for example, uses a 45° cut angle.
