| When there is an axial movement, the in-line bellows will start compressing and the balancing bellows will extend and vice versa. Both bellows will be moving.

Is the bellow really being compressed or is the entire bellow is moving?

Yes, axial as well as lateral expansion joints can be absorbed together in a single bellows design, but the lateral movement would be very minimal compared to a double or universal type expansion joint.

No, you cannot use an axial expansion joint because thrust force will be acting until the gap is closed between the tie rod nuts. When the nuts touch the lugs, the thrust force will not act upon the equipment.
Can I use an axial expansion joint to absorb pipe expansion with gap inside tie rod nuts without passing thrust on the equipment?
No, you cannot use an axial expansion joint because thrust force will be acting until the gap is closed between the tie rod nuts. When the nuts touch the lugs, the thrust force will not act upon the equipment.
