I forgot to tell one thing..

In this case the bellow is supplying by the turbine supplier & i am doing analysis for the turbine supplier..He(Turbine supplier ) Procured the bellow before getting clearance...and i asked him to change the properties of the bellow..that is why i ased the bellow supplier based on what basis he had designed the bellow..for that only he said since the Inline pressure balanced bellow (Pressure thrust will not come for this kind of bellow ) is of tied type the force would not come to turbine flange..but i know when doing analysis with two anchors between the straight length..force & moment will distribute between the two anchors..but the turbine supplier agree with what the bellow supplier is saying (like consider zero weight ) what can i do if my client itself doing like that..that is why i asked the suggestions from you all..thanks alot for your replies...i show this to my EJ supplier..let see what will he say for this...
