INVESTIGATION OF 70-30 COPPER-NICKEL CATAPULT TROUGH HEATER TUBING
2007
Hansen, D. G.
Aircraft carrier catapult trough heater tubing was tested at the Laboratory to determine the effect of inlet steam temperature on rate of tube wall deterioration. It was found that as long as the catapult trough heater was condensing all the steam that entered it, the trough heater tube metal temperature would not exceed saturation temperature. The process involved in tube wall deterioration is erosion. Simulation of shipboard operation in the Laboratory is difficult and costly so further investigations should be made on shipboard. Condensate traps on shipboard should be checked regularly for proper operation.
