The one of the probable reason for tube failure is water hammer due
to non condensable gases in the steam. The best solution I have
experienced in one of such problem was to unplug one of the tube
plug at the outlet of discharge chamber of fin fan cooler and
install high point vents. If the steam loss is very high, consider
installing condensate drum at the outlet of finfan cooler .
