Recently, predicting the remaining life of petrochemical equipment that is used in high temperature and pressure service is an essential element. Specifically, predicting the life of furnace heater tubes used in the range of 850°C to 950°C is an important subject. For economic reasons, it is desirable to replace degraded tubes before tube fails occur. Remaining life assessments are used to help in making tube replacement decisions at proper time. This paper contains Ω parameter and life fraction rule used to life assessment factor to predict remaining furnace tube life, compares the two methods. As the result of assessment, two methods show that the general life of the furnace heater tubes are about 160,000hr and future remaining life is 50,000hr. Based on this result, the heater tubes are enabling to operate until 4years.
