Description

Product Features of Expansion Joint
(1) Economy of expansion joint: 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 of expansion joint: 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 of expansion joint: 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 of expansion joint: 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 of expansion joint: After external force compressed, it can recover to original state when this force is removed.
(6) Wide application of expansion joint: Different rubber material and formula can make product possess different resistance to heat, oil, corrosion, age, abrasion and ozone.
