Product Description

Concentric reducer expansion bellow is a type of pipeline connection component, mainly used to solve the problem of different diameters when connecting metal pipelines. The ordinary type is used to transport air, compressed air, water, seawater, oil, acid, alkali, etc. at -10 ºC~115 ºC, while the special type is used to transport the above-mentioned media or oil, concentrated acid, etc. above -30 ºC~250 ºC.

NO	Name	Material
1	Inner/outer rubber	NR,NBR,EPDM,FKM,PTEF,IIR,CR
2	Strengthen ring	Nylon with rubber
3	Fabric	Nylon
4	Union	Stainless steel,Malleable Iron

Concentric reducer expansion bellow has the following significant characteristics:
1. High pressure resistance ensures the safe operation of pipeline systems
2. Good elasticity, able to adapt to the displacement and deformation of pipelines
3. Large displacement and balanced pipeline deviation
4. Absorb vibration, reduce noise, and improve the comfort of pipeline systems
5. Good noise reduction effect ensures the operational quality of the pipeline system
