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
