Sound Insulation Flexible Rubber Expansion Joint with High Pressure Resistance, Chinese Production

Rubber expansion joints are flexible connection components used in pipeline systems. They are composed of rubber balls (inner rubber layer, reinforcing layer, and outer rubber layer), flanges or threaded joints, etc. 

Main features:
1. High elasticity: Excellent elongation and compression properties, capable of withstanding displacements in multiple directions.
2. High airtightness: Good sealing performance, preventing medium leakage.
3. Resistance to media: Suitable rubber types can be selected based on the transported medium, with a wide range of applications.
4. Light weight: Compared to metal compensators, the weight is significantly reduced, making installation and maintenance convenient.
5. Economical price: The manufacturing cost and maintenance cost are usually lower than those of metal compensators. 

Core functions and roles:
1. Compensation for displacement

(1) Axial displacement: Compression or tension along the pipeline axis.

(2) Lateral displacement: Displacement of the pipeline along the perpendicular direction of its axis.

(3) Angular displacement: Formation of an angle between the axes of two pipelines.
This is its most important function, which can effectively absorb pipeline displacement caused by thermal expansion and contraction, foundation settlement, installation errors, etc., and prevent the pipeline system from being damaged due to excessive stress.
2. Vibration reduction and noise reduction
Rubber is an excellent elastic material, which can effectively isolate and reduce the vibration and noise generated by the operation of equipment such as pumps and compressors, protecting the equipment and the entire pipeline system, and improving the working environment.
3. Reduction of installation stress
During pipeline installation, there are inevitably errors in alignment. Using rubber expansion joints can compensate for these initial deviations, reduce the installation stress of the pipeline and supports, and make the installation more convenient.

4. Corrosion resistance and medium resistance Depending on the specific working conditions, different rubber materials (such as natural rubber, chloroprene rubber, nitrile rubber, ethylene propylene diene monomer rubber, etc.) can be selected to enable them to withstand the corrosion of various chemical media including acids, alkalis, oils, seawater, etc.

Main application fields 
1. Water supply and drainage system: Water supply system for buildings, fire protection pipelines, sewage treatment plants.
2. HVAC system: Cooling water pipelines, chilled water pipelines, connection of fan coil units.
3. Industrial pipelines: Corrosive medium transportation pipelines in industries such as chemical, pharmaceutical, and papermaking.
4. Shipbuilding: Engine exhaust pipes of ships, seawater cooling systems.
5. Power industry: Water circulation system of power plants, flue gas desulfurization system. 

Advantages:
1. Excellent overall performance, capable of both compensating for displacement and reducing vibration and noise.
2. Easy installation and simple maintenance.
3. High cost-effectiveness.
