DN2800 rubber expansion joint for Nuclear power
1. Material lists:
Polyester cord fabric
Steel wire rope
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 rubber joint, concentric reducer rubber joint, eccentric reducer rubber joint.
(2) According to the structure:single ball flexible rubber joint,Double sphere rubber joint,spheres rubber joint, elbow sphere rubber joint.
(3)According to link the form:flange coupling,Threaded 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 rubber expansion 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.
