Exhaust Gas Metal Bellows


Exhaust gas metal bellows 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 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. The inner bellows can be equipped with braided wire and expansion joints , it can eliminate pipeline noise. Therefore, exhaust gas metal bellows is the most ideal compensation component in modern industry pipeline system.
Lanphan exhaust gas metal bellows is various in product structures and complete in specifications, we can custom made different specifications according to client requirements. Our exhaust gas metal bellows use corrugation molding technology, has good flexibility, good gas tightness, product length is not limited, it can satisfy different working requirements. Exhaust gas metal bellows is mainly used in pipeline exhaust air system to absorb vibration, lower noise, compensate installation error and thermal expansion, it is easy to install and helps to lengthen pipeline system service life.
