I am below the frost line in most places but a few areas is a bit
higher. The insulation I thought would help protect the pipe a little.
It is the foam slip on insulation.

Is it drain pipe or does it carry water regularly?

If it's graded to "empty out" by itself due to grade, then you will probably
be fine. If it's full of water all the time, those spots will possibly
freeze depending on their surface area as compared to the below-frostline
surface area and how often you run liquid through them, etc.
