Abstract: The aim of this paper is to analyze the cause of harm in high pressure heater in PT. PJB UP Paiton and to prevent it from happening again. In PT. PJB UP Paiton, several problem related to high pressure heater had occurred before. When the high pressure heater harmed, tube plugging usually applied to fix the trouble. Through this process, the high pressure heater was not fully recovered. The efficiency and failure rate of high pressure heater is decreased and increased respectively. Hence, a root cause failure analysis is conducted to accurately determine the cause of the problem. The result shows that the cause of failure in high pressure heater are the increase of feedwater velocity, the increase of extraction steam velocity, change of flow patter and heat transfer inside high pressure heater and radial displacement tube that over limit. Based on this result, redesign of high pressure heater is performed by increasing the capacity of feedwater flow in high pressure heater and decreasing the feedwater velocity.
