Hi Andreas,
you can use a three-point arc and mark a distance of 16mm from the center of the tube that you have created and use the sweep option in the pull command to generate the deflected tube. 
step1. Mark a line 16 mm from the center of the tube.
step2. Create a three-point arc 
step3. Create the same diameter of the tube and pull using the Sweep option along the arc. 
Keep in mind the length of the tube will change. Do you want the length should remain the same after bending? Please specify your question a little bit in detail. what type of deflection are you expecting? Will it be a circular arc?
