Product Description

Product Description

NHFLEX-D TYPE Union Thread Connection Flexible Rubber Expansion Joints Pipe Connector Rubber Compensator

A Union Thread Rubber Expansion Joint is a type of flexible connector used in piping systems to absorb thermal expansion, vibration, and mechanical shock. It is designed to allow for movement in the pipeline without causing stress or damage to the system. Union Thread Rubber Expansion Joints feature a threaded connection, which allows for quick and easy installation and maintenance, saving downtime and labor costs in various applications, such as HVAC and heavy industrial applications.

Union Thread Rubber Expansion Joints are suitable for a wide range of applications, including water, wastewater, chemical processing, power generation, and marine applications.

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.

* Pressure/Vacuum rating is based on neutral installed length(F/F)
Pressure rating is based on 30ºC operating temperature.The pressure rating is reduced at higher temperatures.
Weights in the above table are joints with BSPT Malleadble Cast Iron threaded  connections.
Rated pressure in the above table is the maximum "working pressure". Test pressure is 1.5 times "working pressure", Burst pressure is 4 times "work pressure".
Normally, the connections are based on BSPT, NPT or other standards are available upon request.

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.
