Titanium heat exchanger corrosion failure

Under-deposit corrosion attack on titanium heat exchanger tubes where river silt accumulated; replacement of the entire heat exchanger. Cautionary case against the assumption that "titanium won't corrode."

Not that titanium tubing won't corrode. I've had under-deposit corrosion attack on titanium tubes if you just let dirt get in the system. One time in New York — I think I told you about the titanium fire — these guys were spraying water on a titanium fire, and when you do that you get titanium oxide plus hydrogen, so you actually end up creating a bigger flame because you're generating hydrogen by spraying water on burning titanium.
