Vacuum bellows expansion joint is a kind of axisymmetric tubular shell, its generatrix is in shape of corrugation, mainly used for compensate equipment or pipeline’s axial and lateral displacement under vacuum environment.
DESCRIPTION

Exhaust gas metal bellows expansion joint is the important jointing element in exhaust piping area. Taking advantages of its good gas tightness, and use hydraulic pressure technology when forming, use water as medium, the exhaust gas metal bellows is in favour of discharging tail gas, it helps to decrease environmental pollution which caused by engine tail gas to the lowest point.


Exhaust gas metal bellows expansion joint is used to absorb vibration from exhaust air system, also to prevent excessive thermal deformation, so as to offer reliable guaranty for pipeline systems. Stainless steel material is the main material for exhaust gas metal bellows, for it can bear high temperature and salinity corrosion. It is the most ideal compensation component in modern industry pipeline system.
