Sir
Thank you very much for your responce . I am sorry it is not presure thrust I have model with tie rod & no considerable load is coming is sustain case ( pressure thrust load come both in sustain & operating case for untied bellow ). It is thermal load coming in operaing & design case . Pump nozzle allowable nozzle load is very low given by vendor.

I am very curious wheather I can put limit stop after tied expansion bellow ( As I have seen our old previous project document )

Once again thank you very much sir

Regards

Habib
