Product Introduction
The commonly used Eccentric Rubber Expansion Joint in daily life is also known as rubber pipe flexible joint, flexible rubber joint, flexible rubber joint, flexible rubber joint, high-pressure rubber joint, rubber shock absorber, compensator, etc. The rubber flexible joint can reduce vibration and noise, and can play a compensation role for thermal expansion caused by temperature changes. It is widely used in various pipeline systems. Eccentric Rubber Expansion Joint is mainly used for the lifting and transmission of raw water and sewage, water supply and cooling circulating water of fossil-fuel power station, pipeline transportation of chemical substances in metallurgical industry, condensate water, chemical industry, cooling and dilution in petrochemical industry, and flexible connection between long and short distance pipelines in other industries. Because rubber has high wear resistance, it is also suitable for low-temperature transportation of particles, powders, and vapors in all industries. Eccentric Rubber Expansion Joint is mainly used for the connection of pumps, valves, fire equipment, pipelines with high vibrations, and pipelines with frequent changes in temperature and cold.
Features of rubber expansion joint:
1. Small volume, light weight, good elasticity, easy installation and maintenance.
2. Transverse, axial and angular displacements may occur during installation, which are not restricted by the pipeline not concentric and the flange not parallel.
3. When working, it can reduce the transmission noise and strong vibration absorption ability
