Product Description

Rubber expansion bellows is a type of pipeline joint with high elasticity, high gas tightness, medium resistance, and weather resistance. It is mainly composed of inner and outer layers of rubber, curtain layers, and steel wire rings to form a tubular rubber component, which is vulcanized and then combined with metal flanges or parallel joints to form a loose sleeve. Each part has its specific function and function, together forming the unique structure of rubber joints.

NO	Name	Material
1	Reinforcing ring	Hard Steel Wire
2	Flange	Q235,SS304,SS316,PVC
3	Reinforcing cord	Nylon Tire Cord
4	Inner/outer rubber	NR,NBR,EPDM,FKM,PTEF,IIR,CR

 Performance characteristics of rubber joints:

1.Small size, light weight, good elasticity, and easy installation and maintenance.
2.During installation, lateral, axial, and angular displacement can be generated, without being limited by pipeline misalignment or flange non parallelism.
3.It can reduce structural transmission noise and has strong vibration absorption ability during work.
