flexible rubber joints Buried Protective Device

The flexible rubber joint buried protective device developed by our company is designed with enough space around and has no influence on rubber joints displacement performance and can separate rubber joint from exterior earth layers and keep pipes freely moving at device ends without resistance. After installing pipes lines, the backfilled ground will be leveled off as usual, on which, vehicles can run well, heavy materials are placed or equipment be installed.

Special attention: please provide buried depth in order so that we can design reasonable protective device for you. Generally the device can be used for over 30 years if anti-erosion on the device surface is well done.   

1.Product Performance:

GJQ(X) series flexible rubber joint is a kind of flexible connection, mainly used to deliver liquid, gas, solid, etc. It adopts sphere body structure to compensate displacement, insulate vibration and reduce noise, which is a new rubber damping product.


2. Product Features:

(1) Economy: Compared with the systems of mechanic stretching and material damping, it has the advantages of little space covering, light weight, easy assembly and disassembly, labor saving and low cost. Its smooth inner wall can reduce flow resistance. It has good water tightness, so there is no need of gasket during the installation. It has wide application, large temperature-resistance scope and long working life. (This product can be used for 20 years if it is used indoors.)

(2) Displacement: Flange is free from pipe decentraction and imbalance. Its good flexibility allows compression, extension, distortion, deflection of vertical displacement, etc. which can prevent the pipeline from damage of deformation and foundation settlement arising from expansion caused by heat and contraction caused by cold.  

(3) Shock and noise absorption: The large damping of rubber sphere can effectively buffer and isolate vibration, control and reduce mechanical vibration, and absorb fluid impact noise. The reasonable installation between vibrating machine and metal pipe can decrease structure-borne noise by 15-25 decibels.

(4) Pressure resistance: The multilayered sphere structure can especially endure internal pressure, withstand strong blasting force and impact, and prevent deformation from external pressure. There are many pressure standards on work piece.  

(5) Reducibility: After external force compressed, it can recover to original state when this force is removed.

(6) Wide application: Different rubber material and formula can make product possess different resistance to heat, oil, corrosion, age, abrasion and ozone.



(1) According to appearance:Concentric with diameter flexible rubber joint, concentric reducer flexible rubber joint, eccentric reducer flexible rubber joint.

 (2) According to the structure:single ball flexible rubber joint,Double sphere flexible rubber joint,spheres flexible rubber joint, elbow sphere flexible rubber joint. 

(3) According to link the form:flange flexible rubber joint,Threaded flexible rubber joint 

(4) According to working Pressure:0.25MPa,0.6MPa,1.0MPa,1.6MPa,2.5MPa,6.4MPa


4. Application Range

Equipped with the excellent comprehensive performances of flexible rubber joint, the product can be used for lift and transportation of raw water and sewage, transportation of water supply, cooling cycle water of thermal power plant, condensate water of metallurgy industry and chemical materials of chemical industries, cooling and dilution of oil and chemical industries and flexible connection of other industries. It is also suitable to transport all grain and powder material and gas for its high abrasive resistance.
