GJQ(X)-4Q-II Four Sphere Flexible Rubber Expansion Joint
GJQ(X)-4Q-II rubber flexible joint belongs to four-sphere flexible rubber expansion joint. Through curing forming, tubular rubber, which is compounded by inner and outer rubber, cord fabric and bead ring, combine with metal flange or parallel loose joint to be such rubber flexible joint.
GJQ(X)-4Q-II four sphere rubber flexible joint has resistance of high pressure and heat, good elasticity, large displacement compensation, easy installation, and remarkable shock-absorbing, noise reduction advantages. It can be widely used in flexible connection of pipes in short distance, such as raw water and sewage lifting and transport, water supply and cooling water circulation of thermal power plant, metallurgy, condensate water, transport of chemical substances in chemical industry, cooling & attenuation in petrochemical industry.
Lanphan rubber expansion joint is made by various rubber materials. General rubber expansion joint’s inner and outer rubber layer use NR, SBR or BR; oil resistant rubber expansion joint use NBR; acid-base resistant, high temperature resistant rubber expansion joint use EPDM.
The flange made by Lanphan meet the international standard of DIN, ANSI,ASME, JIS,BS,EN and other standards, our flange thickness, smooth surface roughness, the accuracy of the caliber are within the tolerance of control thousand classification.
Lanphan’s rubber joint brief paragraph internal coil with high quality metal wire, can effectively improve the tensile stress ability of the port, and cross section sealing layer is bigger than other manufacturer, mainly in order to increase the contact area, improve the sealing performance.
