High Quality Low Price Flanged Double Spheres Rubber Expansion Joint

Product Description          Double ball rubber joint can be divided into single ball, double ball, different diameter body, curved ball and wind pressure coil. A tubular rubber piece consisting of an inner and outer rubber layer, a cord layer and a traveller is vulcanized and formed and then loosely combined with a metal flange or a parallel joint.   Product Parameters Double sphere rubber bellows coupling is generally consist of the inner and the outer rubber layer and fabric reinforced layer (the enhancement layer has a multilayer spreading cord fabric), vulcanization molded in high temperature and high pressure , then assembly together with rubber tube and metal flange or parallel joint sleeve.   No.    Name                                           Material1    Inner and outer rubber             NR,NBR,EPDM etc2    Frame                                     Nylon cord fabric3    Pressuring ring                        Steel wire4    Flange                                    Stainless steel or Carbon steel                                                                    galvanized    Nominal diameter DNLengthmmCenter diameterof    the boltbolt hole diameter bolt   quantity              Axial displacementHorizontaldisplacement(mm)Deflexion anglemminchExtension(mm)Compression(mm)(a1+a2)°50216512518430504535°652 ½17514518430504535°80317516018835504535°100422518018835504035°125523021018835504035°150632524022835504035°200832529522835504035°25010325350221235603530°30012325400221235603530°Technical Conditions                      DN200-DN300(8-12)          DN50-DN150(2-6)       JGD-A(1)                                   JGD-A(2)                        JGD-A(3)workiing pressure  MPa          1(10)             1.6(16)                  2.5(25)burst pressure   MPa          2(20)             3(30)                  4.5(45)vacuum  degree  KPa        40(300)           53.3(400)                86.7(650)  applicable      temperature           -15~115ºC  specially  reachable  -30~250ºC  applicable medium             "Air,water,sea water,vacuum,hot water,oil,acid,alkali,etc."        Data above is only for reference, if  you want much more information, please contact us.We have various types of molds and multiple sets rubber vulcanizing equipment, which can meet mass production and customization requirements.  Production process   products application  This product is widely used in chemical industry, construction, water supply and drainage, petroleum, heavy and light industry, refrigeration, sanitation, plumbing, fire protection, electric power and other basic engineering.According to different materials can be made of acid resistance, alkali resistance, corrosion resistance, oil resistance, high temperature resistance, radiation resistance, wear resistance, aging resistance and other varieties, to adapt to a variety of media and the environment.We can also do pressure testing.   Company Profile      Gongyi Ruixuan pipeline equipment factory was founded in 1996.It  is an excellent  enterprise  specializing  in manufacturing  and selling pipe fittings.It's located  in Xicun village ,Gongyi  city,Henan province ,the concentrated  area  of pipeline equipment industry  in China.The  company factory  is located  in Xicun town pipeline equipment industrial park.It covered an area of20000  square  meters.       At present, the company has the production capacity of pipeline equipment with a maximum diameter of 4000mm, and its main products are: Steel expansion joint, flexible waterproof sleeve, large diameter flange, double flange force transfer expansion joint, large deflection loose sleeve compensation joint, spherical compensation joint, sleeve compensator, bellows compensator, non-metallic compensator, rubber expansion joint, DC medium no thrust sleeve compensator, flexible expansion pipe and other pipeline equipment.
