摘要：
Over 5 years service, some observed leakages of single tubes resulted in their shut-down. At the end of this period, 140 tubes of a total of 1000 were found to be leaking and the heat exchanger was shut down for an overhaul. A metallographic investigation was undertaken to determine the cause of premature failure of the tubes. The water flow rate through the heat exchanger was reportedly close to the turbulent flow rate.
