| Abstract: | Corrosion failure analyses were carried out on heat-exchange tubes according to running conditions for the frequent-leaking problem of high-pressure heat exchanger E408I. It was pointed out about the conditions that bring stress corrosion crack by professional detctions and analyses according to specific running conditions.At the same time one reason was analysed for more failure rate after devices update. The results and suggestions have good reference for prevention of stress corrosion of tube bundle for heat exchanger running under the similar conditions and for heat exchanger updated. |
