DN200 PN16 factory custom large diameter pipe concentric reducer Ss304 flange connector rubber expansion joint
How the product works
1. Flexible connection: The concentric reducer rubber joint can compensate for the displacement of the pipeline due to thermal expansion, cold contraction, vibration and other factors through the elastic deformation of the rubber ball, and ensure the stable operation of the pipeline system.
2. Shock absorption and noise reduction: The rubber joint has good shock absorption performance, which can effectively absorb the vibration and noise in the pipeline system, reduce the resonance phenomenon during the operation of the equipment, and thus reduce noise pollution.
3. Absorption displacement: The joint can produce displacement in the axial, transverse and angular directions, adapt to the movement of the pipeline in different directions, protect the pipeline from the influence of stress concentration, and prolong the service life.
The manufacturing process and material characteristics of the product
During the production process of concentric reducer rubber joints, the inner layer is subjected to high pressure, so that the nylon cord fabric and the adhesive layer are better combined, so as to improve the working pressure and quality. Common materials include natural rubber, nitrile rubber, EPDM, etc., which have good elasticity, abrasion resistance, aging resistance and tear resistance, and are suitable for a wide temperature range (-45°C to +60°C).
Product Advantages
1. Excellent corrosion resistance
2. Excellent resistance to high and low temperatures
3. High elasticity and flexibility
4. Wide range of applications
5. Ease of installation and maintenance
6. Environmental protection and economic benefits

Product Applications
1. Water supply and drainage system
In water supply and drainage systems, concentric reducer rubber joints can effectively buffer and absorb pipeline vibration, reduce pipeline vibration and pressure fluctuations caused by water flow changes, thereby protecting the pipeline system and prolonging service life. Especially in high-rise buildings, such joints are resistant to high water pressure and prevent pipes from deforming and rupturing.
2. Chemical and petroleum industry
In the chemical and petroleum industries, concentric reducer rubber joints can withstand harsh environments such as high temperatures, high pressures, and strong acids and alkalis. Its pressure-resistant performance and elastic design make it excellent when transporting corrosive media, ensuring the stable operation of the piping system.
3. Pharmaceutical and food processing industries
The pharmaceutical and food processing industries place high demands on the tightness and corrosion resistance of pipes. Concentric reducer rubber joints can not only ensure the tightness of the pipeline system and prevent fluid leakage, but also choose food-grade or pharmaceutical-grade rubber materials according to needs to ensure that the fluid is non-toxic and harmless and meets sanitary standards.
4. Thermal & HVAC Systems
In thermal and HVAC systems, concentric reducer rubber joints can effectively absorb pipe deformation caused by thermal expansion and contraction, and reduce pipe damage caused by temperature changes. Its shock-absorbing and noise-reducing characteristics also make the system run more smoothly.
