Wouldn't she simply let go of the pipe, or put it in a pocket? And if it's the latter, that's true for most DFs - things in pockets stay in pockets for the same reason clothes don't rip off and cause Lucci to fight naked.

Paula is not seen holding the pipe from the beginning of the fight until after she uses that roll move and Nami runs away. There is absolutely no reason to assume it transforms with her.
