Colefurnace Repair

QUESTION:

The big joke in the USN is one was supposed to know two ways out of any space-even if there was only one access. Those of us in the main engineering spaces were fully aware if we took a hit more than likely we wouldn't realize it before we were dead. The USS Cole gives a very fine example. IIRC, the main engineroom forward and aft bulkheads retained their watertight integrity. That's a plus, as is its power plant is gas turbine-no 600/1200 PSI boilers to act as secondary bombs. Cold sea water hitting a super hot pressurized boiler. That's something you don't want to be anywhere near.

ANSWER:

I saw something similar. When I got out of college I was developing a process to make SiC "whisker" (ultra high strength single-crystal fibers). The process involved heating the raw a materials in a tube furnace to 3500 C. Each batch was in a graphite tube that were pushed in sequence through the furnace (which of course had a nitrogen or argon atmosphere).
The tubes were cooled after the "fire zones" in a water-cooled jacket. One day, a point failure in the jacket opened and the water was instantly turned to steam. The furnace started shooting out graphite tubes that looked like tracer bullets. They crashed harmlessly into a curing oven (well, not harmlessly to the oven). Had someone been standing in front of the furnace, a tube would have gone right through them like a hot knife through butter and cauterized the wound as well.
