Hi nordzway, also maybe a different way which would be easier would be to rotate the object around its own end rather than making a copy off to the side and then orienting the copied object.

To do the rotation way, select your pipe segment and run Transform > Rotate > Rotate Axis. Pick the axis line at the endpoints you can snap to, then check the "Make copies" checkbox, type 180 and push Enter to make a copy of that segment rotated by 180 degrees and then push Escape to exit the command.

Then if you want to pivot the new segment around, have an axis line prepared and do another Rotate axis of the new segment with "Make copies" disabled.
