Analysis on Residual Stress of Steam Condenser Pipe
Using the blind-hole method to test the residual stress of the condenser tube, and using the numerical analysis method, the stress state of crater location in steam condenser pipe was analysed to provide the basis for the analysis of the cause of the tube bursting accident.The residual stress and working stress caused by welding and forced counterpart were superimposed in the assembling process of tube panel,part of the weld will be at a higher level of stress, sometimes even more than its yield strength.Analysis and demonstration of the slotting effect of the steam condenser pipe wall were also carried out by the method of stress testing and numerical simulation analysis.
