Titanium is a candidate material for use as heat-exchanger tubing in desalination plants because of its excellent resistance to corrosion. In fact, one plant owned by the Aluminum Division of Martin Marietta Corporation, which contains about 100 miles of extruded titanium tubing, has been in successful operation since 19651,2 . Operating experience with this plant has been sufficiently good to warrant the construction of an additional plant on an adjacent site3 . Both plants utilize seamless unalloyed titanium tubing and operate in the 110°C (230°F) temperature range. No corrosion failures have been found in the above plants. This is in contrast to the laboratory observations of Bohlman and Posey4 , who reported crevice corrosion of titanium in chlorides solutions at temperatures in excess of 100°C (212°F), and the subsequent studies of Griess5 , which indicated that such crevice corrosion was associated with the development of an acidic pH (= ~ 1) in the solution within the crevice.
