Product Description

Product Description

NHFLEX-A TYPE Flanged Single Ball Flexible Rubber Expansion Joints/Shock Absorber/Noise Absorber/Vibration Dumper

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. 
 

A rubber flexible joint is a type of pipeline connector designed to link pipes of different materials, diameters, or alignment. It accommodates variations in pipeline layout, whether they involve mismatched axes or straight-through connections.

These joints are essential for absorbing deformation and displacement caused by thermal expansion, contraction, vibration, or other dynamic forces in a piping system. By doing so, they help maintain system integrity and ensure safe, continuous operation.

In addition to mechanical flexibility, rubber joints provide excellent vibration isolation and significantly reduce noise transmission through the structure. Their strong shock-absorbing capacity makes them suitable for demanding applications.

Applications:

1. Handling Thermal Movement:  Compensate for pipe length changes caused by fluctuations in temperature.

2. Dampening Vibrations and Noise: Isolate and reduce vibrations and noise generated by mechanical equipment like pumps or motors.

3.Correcting Misalignment: Help accommodate slight deviations in pipe alignment during installation or operation.

4.Absorbing Pipe Movement: Flexibly respond to axial, lateral, or angular shifts in piping systems.

* 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".

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.
