Thermal growth, equipment movement, vibration or pressure pulsation may generate movement in a rubber joint piping system. When this movement is not absorbed by the piping system itself, an expansion joint is the perfect solution. A Rubber Expansion Joint is flexible connector fabricated of natural or synthetic elastomers, fluoroplastics and fabrics and, if necessary, metallic reinforcements used to absorb movements in a rubber joint piping system while containing pressure and a medium running through it.
Rubber Expansion Joints are manufactured considering
- Chemical and Temperature resistance of internal layers
- Pressure-resistant reinforcing fabrics
- Weather, ozone and UV-resistance of external layers
There are four basic movements that can be absorbed by a rubber Expansion Joint
Advantages
- Minimal face-to-face dimensions while absorbing large movements
- Low Spring Rates due to inherent flexibility of rubber
- Corrosion and Erosion resistance
- No gaskets required for installation
- Reduced fatigue factor
