| Abstract: | By using piping stress analysis software CAESAR Ⅱ,stress analysis for the main steam piping connected to one turbine under multi conditions were carried out.From the results of the simulation and calculation for the conditions of design,warming piping I,warming piping Ⅱ and installation,it was concluded that the most severe condition is that of warming piping Ⅱ.The illustration of this condition and the stress analysis used in this article may be referenced in further study of the arrangement of main steam piping connected to turbine. |
