Could you try again? Expansion joints are supposed to control cracking of concrete.

"pipe crossing"?

If the concrete next to its expansion joint moves, then maybe the pipe should also move to match....

Yes, if the concrete expansion joint separates, the pipe will have to move with one side or the other, hopefully.
