Double Sphere/arch Flexible Rubber Expansion Joints are designed to absorb movements and stress on piping systems, Double Sphere Flexible Rubber Expansion Joints' connecting distance is relatively large.Compared with the Single Sphere Flexible Rubber Expansion Joints,the maximum pressure which He can withstand is smaller than Single Sphere Joint. But, in the middle part of the rubber joint is pressurized ring. Each layer is impregnated with a rubber or synthetic compound. This allows movement and flexibility between the layers of fabric.Double Sphere Flexible Rubber Expansion Joints is easy to install and maintain because of the small volume and flexibility.The inner seamless high-pressure rubber joint is developed by our own which prevents corrosive medium from etching the inner wall of the rubber joint in high temperature, acid, alkali and oil resistant pipeline. We can assure the quality and if you put up some other specific requirement, we will take them into consideration too.
• Rubber body length can be customized.
