Abstract The structure,function and characteristic of expert system of Fitness-For-Service for petrochemical(ESFFSR)was introduced in this p aper .In ESFFSR,aritifical neural network(ANN)and Fitness-For-Service technology were used to evaluate the corrosion defects in refinery.ANN is used to make the rela tionship between corrosion rate and the effect factors for general corrosion.Fit ness-For-Service models are used to analyze the local corrosion.Based on the AN N and Fitness-For-Servic models,ESFFSR can make suggestions for lower temperatur e and pressure if the defect is incompetent automatically.In addition,ESFFSR wou ld give out the corrosion type,mechanism,characteristics and effect factors on l ine in petrochemical.The selected material of commended tables to anti-corrosio n for distillation,catalysis and coking equipment were also given in ESFFSR.

Key words: petrochemical corrosion database artificial neural net work expert system
