Very unlikely. The collapsing bubble effect, although much more destructive
to pipes than water hammer, sounds pretty innocuous, sort of like sand is
running in the water stream.

The clanking of hot water and steam pipes I believe to be due to the thermal
expansion of the pipes. This explains why the effect is most prominent when
the furnace comes on after a spell.
