The coal-based steam power plant accounts for the largest electricity generation in Indonesia. Disruption in operation mostly caused by a failure of a component of the system and considered a serious problem and must be prevented. Failure can be originated from operations as well as the design. In the present work, a root cause study was performed on failure elbow in the steam line from the high-pressure heater (HPH) to the deaerator. The failure occurred only after 5 years of operation. The analysis was started with a visual examination, material verification, microstructural investigation, thickness measurement, and computational modelling. The analysis and simulation study showed that the failure of the elbow caused by two-phase flow where steam quality was compromised. The recommendation was to examine the HPH and to find possible leaks of the waterside to the steam side in the HPH system.

The Efficiency of the piping system largely relies upon bends used to connect pipes. The piping system is at the highest risk due to stress concentrations at abrupt cross-sectional change, large support less valves, vibrations, and lack of the assessment of fatigue failure. Bends undergo different combine loads involving internal pressure, in plane cyclic loading, out of plane cyclic loading, dead weight along with different thermal conditions. Compared to straight pipe miter bend has more complex mechanical behavior and critical stress-strain locations due to its asymmetric shape and hence miter bend undergoes plastic failure in the form of collapse, ratcheting, and fatigue that leads to component failure at the end. This paper presents review for behavior of miter bend considering important fracture mechanics parameters such as limit and collapse load, local wall thinning, ratcheting, creep, and their effects on fatigue life. The review also tabulates all fatigue life equations used by researchers for predicting fatigue life. Topics for further research on miter bends such as out of plane loading, vibration induced fatigue and creep are also noted.
