Name: Straight Internal Pressure Balanced Bellows Expansion Joint Displacement direction: Axial
Nominal drift diameter: DN600 - DN1600
Working pressure: 0.25Mpa - 0.6 Mpa
Working temperature: -20 - +400.

It has a working pipe at each end and a balance pipe in the middle which endures pressure and thrust, changes ist stress situation, balances the additive sideway stress generated in the fixed framework by pressure on the tube saclike cavity cross section or the bending point, release the tube and the fixed framewework volume, lengthen the service life of tube so as to ensure the safe working of the tube.
