Corrosion Resistance: Rubber expansion joints are made from high-quality rubber materials that exhibit excellent resistance to corrosion. They can be used with various media such as water, oil, and gases. Elastic Deformation: Rubber expansion joints can absorb stresses and vibrations caused by temperature changes, vibrations, or pipe movements in pipeline systems through their elastic deformation. This helps protect the pipeline system from damage. Shock Absorption and Noise Reduction: Rubber expansion joints effectively reduce the transmission of vibrations and noise in pipeline systems, providing a quieter and more stable working environment. Easy Installation and Maintenance: Rubber expansion joints have a simple structure, making them easy to install and maintain. They also have low maintenance costs.
Applications:
Compensating for Thermal Expansion and Contraction: Rubber expansion joints compensate for thermal expansion and contraction caused by temperature variations in the pipeline. They prevent excessive stress on the pipeline system due to temperature changes, thereby protecting the pipes from damage. Absorbing Vibrations and Impacts: Rubber expansion joints absorb stresses caused by vibrations and impacts in the pipeline system, reducing the transmission of vibrations and noise. This helps protect the pipeline and related equipment from damage. Compensating for Pipe Movements: During installation and operation, pipeline systems may experience certain degrees of pipe movement. Rubber expansion joints compensate for these movements, ensuring the proper functioning of the pipeline system. Leak Prevention: Rubber expansion joints provide sealing performance in pipeline systems, reducing the risk of leaks and ensuring the safe operation of the pipelines.
