Pawlowski is, again, correct.
The water on the pipe surface comes from the air.
Thus, a well sealed insulation jacket will not allow moisture to fomr

How well sealed is "well sealed"?
Is it enough to buy the Home Chepot middle-grade stuff that comes with
taped edges that you push together?

My sense is that the adhesive tape is enough to keep it on the pipe but not
enough to make a real seal.
Is there stuff that is better to buy or should I cover the seam with
something like duct tape?

Thanks

If you put it on when the pipe is dry, almost anything will keep the
humid air from touching the pipe after that. No humid air, no
condensation. If part of the pipe is dry, wipe it off with a towel
first.

Personally, I doubt mold or anything will grow on a little dampness on
a copper pipe, but this should prevent any.

If youre still not sure, open part up after 6 months and check it out.
But you have to look right away. The moment you open it up, humid air
might start to condense on the pipe.
