Product Description

Rubber joint (also called rubber soft joint, rubber expansion joint or rubber compensator) is a flexible pipe connection device made of rubber material, mainly used to absorb vibration, noise and displacement in the pipeline system. It has good elasticity, corrosion resistance and sealing performance, and is widely used in water supply and drainage, HVAC, chemical industry, power and other industries.

Main functions of rubber joint
1. Vibration absorption:
- Rubber joints can effectively absorb the vibration generated by the operation of equipment such as pumps and compressors in the pipeline system, and protect pipelines and equipment.
2. Noise reduction:
- Through the elastic deformation of rubber, the noise propagation in the pipeline system is reduced.
3. Displacement compensation:
- It can absorb the axial, lateral and angular displacement of the pipeline caused by thermal expansion and contraction, foundation settlement or installation error.
4. Good sealing performance:
- Rubber materials have good sealing performance and can effectively prevent medium leakage.
5. Strong corrosion resistance:
- Rubber joints are suitable for water, air, weak acid, weak alkali and other media, and have good corrosion resistance.

Main structure of rubber joint
1. Rubber body:
- Made of natural rubber, synthetic rubber or special rubber, with good elasticity and corrosion resistance.
2. Reinforcement layer:
- Usually polyester cord or wire mesh is used to improve the strength and pressure resistance of rubber joints.
3. Flange or threaded connection:
- Used to connect rubber joints to pipeline systems, common flange connection and threaded connection.
4. Liner:
- Used to protect the rubber body from medium erosion or corrosion.
Main types of rubber joints
1. Single ball rubber joint:
- Simple structure, suitable for general occasions, able to absorb axial, lateral and angular displacement.
2. Double ball rubber joint:
- Has greater compensation capacity, suitable for occasions requiring larger displacement.
3. Concentric reducing rubber joint:
- Used to connect pipes of different diameters, able to absorb vibration and displacement.
4. Eccentric reducer rubber joint:
- Used to solve the eccentricity problem in pipeline installation, while absorbing vibration and displacement.
5. High temperature resistant rubber joint:
- Made of high temperature resistant rubber material, suitable for high temperature medium.
6. Oil resistant rubber joint:
- Made of oil resistant rubber material, suitable for oil medium.
7. Acid and alkali resistant rubber joint:
- Made of acid and alkali resistant rubber material, suitable for corrosive medium.

Application scenarios of rubber joint
1. Water supply and drainage system:
- Used in occasions such as tap water and sewage treatment to absorb vibration and displacement.
2. HVAC system:
- Used in piping systems for hot water, cold water, steam and other media to reduce noise and vibration.
3. Chemical industry:
- Used in piping systems for corrosive media such as weak acids and weak alkalis.
4. Power industry:
- Used in cooling water pipes, steam pipes, etc. to absorb thermal expansion and contraction and vibration.
5. Ship and marine engineering:
- Used in ship piping systems to absorb vibration and displacement.
6. Fire fighting systems:
- Used in fire fighting pipes to absorb vibration and noise.
