Product Description

Product Description

NHFLEX-A TYPE Flanged Single Ball Single Sphere Flexible Rubber Expansion Joints

Rubber joint features:
Small size, light weight, good elasticity, easy installation and maintenance

Rubber joints consist of inner and outer rubber, cord layer and traveler, which are vulcanized and then combined with metal flanges or loose sleeves of parallel joints, are mainly used in pipelines with large vibration and frequent changes of heat and cold, which can absorb the vibration generated by the work of the pump, thus reducing the noise and avoiding the loosening of the screws, and thus are also called shock absorbers or vibration dampers. 

Rubber flexible joint is a kind of pipeline connection parts, can connect two different materials, different straight through or different axis of the pipeline. Rubber flexible joint can relieve the pipeline system due to thermal expansion and contraction, frequent vibration and other reasons caused by pipeline deformation, displacement and other problems, so as to protect the safety operation of the pipeline.

When working, it can reduce the noise transmitted by the structure, with strong shock-absorbing ability. Rubber joints have good comprehensive performance and are widely used in marine industry, chemical industry, construction, plumbing, fire fighting, electric power and other basic projects.

Application:
Water, Sea Water, Fresh Water, Warm Water, Weak Acid Fluid, Soda Fluid, etc. Pipeline
Characteristics:

1. Corrosion Resistance: Rubber expansion joints are made from high-quality rubber materials that exhibit excellent resistance to corrosion. They can be used with various media such as water, oil, and gases.

2. Elastic Deformation: Rubber expansion joints can absorb stresses and vibrations caused by temperature changes, vibrations, or pipe movements in pipeline systems through their elastic deformation. This helps protect the pipeline system from damage.

3. Shock Absorption and Noise Reduction: Rubber expansion joints effectively reduce the transmission of vibrations and noise in pipeline systems, providing a quieter and more stable working environment.

4. Easy Installation and Maintenance: Rubber expansion joints have a simple structure, making them easy to install and maintain. They also have low maintenance costs.

* Supply range can be up to DN3000, detailed data can be offered upon request.
Control units must be used when piping is not properly anchored.
The rated pressure can be above 2.5MPa, but products will only be sold with control units.
Pressure rating is based on 30ºC operating temperature. The pressure rating is reduced at higher temperatures.
Rated pressure in the above table is the maxlmum "working pressure". Test pressure is 1.5 times "working pressure", Burst pressure is 4 times "work pressure".

Main Products

Application

Compensating for Thermal Expansion and Contraction: Rubber expansion joints compensate for thermal expansion and contraction caused by temperature variations in the pipeline. They prevent excessive stress on the pipeline system due to temperature changes, thereby protecting the pipes from damage.

Absorbing Vibrations and Impacts: Rubber expansion joints absorb stresses caused by vibrations and impacts in the pipeline system, reducing the transmission of vibrations and noise. This helps protect the pipeline and related equipment from damage.

Compensating for Pipe Movements: During installation and operation, pipeline systems may experience certain degrees of pipe movement. Rubber expansion joints compensate for these movements, ensuring the proper functioning of the pipeline system.

Leak Prevention: Rubber expansion joints provide sealing performance in pipeline systems, reducing the risk of leaks and ensuring the safe operation of the pipelines.
