【Abstract】 The preventive maintenance during the normal service period of the corroded chemical structural is to ensure the structure fulfill its designed service function in the given service time. On the condition that the continuous service time is given, the main point of the preventive maintenance is the decision of maintenance reliability level. This paper suggest the practical method of the optimum maintenance reliability level decision of the chemical service structure based on the continuous service life time, which is very important for the planning of the maintenance strategy during normal service period of the corroded structures.更多还原
