Rubber expansion joints are the most versatile rubber expansion joints available.
The double arch design has greater allowed movements than the single arch.
The CHANGHONGSHENG Double expansion joints are available in diameters from 1" to 120", and can be made with any elastomer material. Because single, double, and triple arch models are available, various movement requirements can be met. Non-standard designs are manufactured as required.
Robust design with integral rubber flanges for secure connections
Available in multiple rubber elastomers
Available with optional control unit tie rods to prevent overextension
Moves in both axial and lateral offset directions
Second arch provides more movement
Any lower temperature systems requiring thermal expansion, settlement, or other movement where chemically compatible
