Analysis of results of technical diagnostics of shell-and-tube heat exchangers for ranking of service defects and evaluation of their effect on residual life

M. D. Rabkina, A. A. Perepichay, I. I. Perepichay, V. V. Mutas

 
The results of longstanding technical diagnostics of apparatuses of refining complex were analyzed for determination of typical representative of equipment for cyclic strength calculation. Finite element method was used for determination of the effect of local corrosion defect, located in the area around the nozzle, on cyclic strength of shell-and-tube heat exchanger at operating load action.

Keywords: technical diagnostics, shell-and-tube heat exchanger, local corrosion, cyclic strength
