Product Description
As rubber has superior capability in resistance of acid, alkali, oil and electrolyte, rubber joint has become one of the alternatives of stainless steel and been successfully installed in tough demanding applications such as: Chemical, Petrochemical, Marine, Power Generation, Pulp and Paper, Steel Mills, Water and Wastewater Treatment, Building Construction, Heavy Industry, Freezing and Sanitary Plumbing.
This expansion joint is made of high-quality rubber material and has the characteristics of corrosion resistance, high temperature resistance, low temperature resistance, and wear resistance. It can also withstand various pressures and loads while maintaining stable sealing performance, ensuring the safe and stable operation of the pipeline system.
The Clamp Type Flexible Rubber Expansion Joint has the characteristics of easy installation, convenient maintenance, and beautiful appearance. Widely used in industries such as chemical, construction, water supply and drainage, HVAC, etc.
Product Parameters
-
Small volume, light weight, good elasticity, easy installation and maintenance. After installation, it can assimilate horizontal, axial and angular displacement caused by pipeline vibration, it can reduce the noise which produced by the pipeline and water pump etc.
-
High pressure resistance, high temperature resistance, oil resistance, wear resistance, corrosion resistance, acid and alkali resistance.
-
Connect with pump, valve, fire fighting equipment, pipe which vibrate big, pipe which hot and cold change frequently.
-
Natural rubber content of forty-seven percent, can continue to use for 15 years without aging.

Advantage
1. Excellent pressure bearing performance: The Clamp Type Flexible Rubber Expansion Joint can withstand significant pressure during operation.
2. Good shock absorption and noise reduction effect: Due to its use of flexible materials, it can absorb the vibration of the pipeline system, effectively reduce the noise of the pipeline, and reduce the noise pollution of the pipeline system.
3. Strong corrosion resistance: Due to its main material being rubber, it has excellent acid, alkali, and corrosion resistance. Capable of adapting to the needs of various pipeline transportation media.
4. Preventing water leakage: This product adopts a sealed design to effectively prevent water leakage in the pipeline system, thereby ensuring the safe operation of the pipeline system.
5. Easy installation: The installation of Clamp Type Flexible Rubber Expansion Joint is very simple and can be completed using simple tools without the need for complex work procedures.
