Thank you very much for your advice, and i discussed with my client, they are asking me to design the bellow with tieds, kindly advice me, if we have any bellow with tie rods for above straight line pipe and why we can not use the tied bellow in straight line pipe,
I seen one tied bellow, the tie rod each ends we have nuts on outside of the bellow flange but not in inside. So no restrictions during the axial compression (towards inside) and also it try to move axial expansion (towards outside), here I put the bellow between two anchors so only compression, only the tie rods are used for extra safety during the axial expansion. can we use these kind of tied bellow.

Please find attached bellow image for your view.

kindly advice me.

Regards
Rajiv
