PROBLEMS IN COOLING WATER SYSTEMS CAUSED BY POOR DESIGN, OPERATION AND WATER TREATMENT- SOME CASE HISTORIES

摘要

In general, the operation of a cooling water system focuses on water treatment. However in addition, corrosion equipment failures can be caused by other factors such as fatigue or freezing (mechanical overload). The presentation includes some case histories of equipment failures caused by the aforementioned reasons. Furthermore, the case histories demonstrate the importance of undertaking a thorough failure investigation in order to establish the cause of failure and thereby select the correct remedy.
