Abstract:

ln this paper,research is conducted on the piping layout of double-intake steam turbines,puting forward the optimization scheme for

piping layout and suport & hanger setting,and CAESAR ll software is adopted for pipe stress analysis and calculation at the same time,NEMA SM23 standard is followed to check the stress of the nozzle,and finally the characteristics of steam turbine inlet piping arrangement,support  & hanger setting schemes and relevant matters needing attention are discussed.
