Seawater Pipeline Noise Vibration Absorption Rubber Metal Pipe Connector

Product Description

Product DescriptionNHFLEX-C TYPE Rubber Metal Pipe Connector
Rubber Metal Pipe Connector can be installed near pumps, compressors, regulators, valves and machines to eliminate noise transmission and to absorb small vibration occurance in pipelines.
Structural:
Cylindrical rubber body with vulcanized flange to the flange holes (The cylindrical body: EPDM elastomer + 2pc flanged inserts).The rubber-metal pipe connector is self-sealing, so that no additional seals required.
Characteristics:
1. Corrosion Resistance: Rubber metal pipe connectors 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 metal pipe connectors 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 metal pipe connectors 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 metal pipe connectors have a simple structure, making them easy to install and maintain. They also have low maintenance costs.Product ParametersStandard Specification:

* Stable pipeline fixed points and proper pipeline are required to absorb axial forces.
The rubber metal pipes are installed free of tension.
The mounting length should be 70mm, do not load on train, twist or bend position.
The installation should be in an easily accessible location where maintenance and inspection of the system is easy to do.
Additional seals are not required, since rubber protrudes at the sealing surface.
Keep the joint away from heat sources such as welding machines or sun light.
Do not assemble the joint directly in touch with rubber surface or other fitting.Main Products

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.
