GJQ(X) Flexible Rubber Expansion Joint

Performance of Flexible Rubber Expansion Joint：

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. 

Features of Flexible Rubber Expansion Joint：

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. Flexible Rubber Expansion Joint 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. (Flexible Rubber Expansion Joint can be used for 20 years if it is used indoors.)

Displacement: Flange is free from pipe decentraction and imbalance. Good flexibility of Flexible Rubber Expansion Joint 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. 

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. 

Pressure resistance: The multilayered sphere structure of Flexible Rubber Expansion Joint 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. 

Reducibility: After external force compressed, Flexible Rubber Expansion Joint can recover to original state when this force is removed. 

Wide application: Different rubber material and formula can make Flexible Rubber Expansion Joint possess different resistance to heat, oil, corrosion, age, abrasion and ozone.
