| Summary: | A coal fired power plant with its normal operation temperature of 540ºC in which its
steam trap bypass tube in that power plant was totally fractured. The aim of this study is to explore
the evidence related to the steam trap bypass tube failure and to determine the failure mechanism
and the root cause of the failure and to give an appropriate recommendation. From the evidence
with considering the contribution factors such as temperature, pressure and environment, a fault
analysis was made and it can be concluded that the cause of failure to the steam trap bypass is due
to multi causes which consists of creep failure and hydrogen damage. |
