The bellows compensator is an expansion joint made of a metal bellows that can expand and contract in the axial direction and also allows a small amount of bending. A common bellows compensator is an axial bellows expansion joint that is used for axial length compensation on the pipe. In order to prevent exceeding the allowable compensation amount, a protective pull rod or a guard ring is disposed at both ends of the bellows, and a guide bracket is disposed on the pipe at both ends connected to the bellows compensator.
