Take a close look at your chain wrench, what you probabbly have is a glass tube cutter for gage glasses. See if the chain sections have a little wheel in the center. I have one of the gage glass cutters that is a clone of the one in the picture. Of course you could use it as the chain wrench on really small and light duty piping.
