3 CONCLUSION
Case studies reported indicated that actual mechanism of boiler tube failure can be
identified through systematic metallurgical investigation. Based on the mechanism
of failure, sequence of events that led to failure can be drawn and corrective actions
can be suggested for preventing re-occurrence of similar failure. Hence, it may be
concluded that investigation into the cause of boiler tube failure is very much helpful
in improving the availability and reliability of boilers.
