Double Dome Rubber Expansion Joint

Double sphere rubber expansion joints are flexible connectors made of natural rubber or synthetic elastomers, steel rings and fabric. When necessary, metal reinforcements relieve stresses in the piping system due to heat, mechanical vibration and/or movement. Rubber expansion joints relieve stresses caused by thermal expansion and cold contraction of the pipeline. Piping systems always move due to changes in ambient temperature, differences in the temperature and composition of the materials handled. Expansion joints absorb this movement, eliminating the risk of bending or opening, resulting in high replacement costs. Rubber expansion joints solve the expected vibration, noise, shock, corrosion, wear, stress and space problems. The piping system uses a double sphere design to absorb pipe movement, relieve stress, reduce system noise/vibration, compensate for misalignment/deflection and protect rotating mechanical equipment from start-up shock. Rubber expansion joints can be made of different rubber materials depending on the medium and application. They are designed to withstand axial, horizontal, angular and torsional movements and vibrations in pipelines. Some of the notable features and benefits of rubber expansion joints include superior noise and vibration control, easy installation of rotating metal flanges, availability of a wide range of flange materials, wide range of services, light weight, and the most economical flexible connectors.
Multi-wave design increases the length of the rubber joint. Increased compensation. Special cold water . Hot water . Compressed air. Natural gas, etc. Unique design. Novel structure and good sealing performance solve the burst and damage of thermal expansion and cold contraction to the pipeline connection equipment, effectively improve the life cycle of the pipeline and the protection of the equipment. Double spheres have greater compensation than single spheres. Flexible double ball rubber joint. Double ball rubber flexible joint.
