High pressure single sphere flexible rubber expansion joints coupling also called Pipe Expansion Joint, Rubber Expansion Joints, Bellow Expansion Joint, Rubber Bellow Joint, Pipe Rubber Joints, Flexible Rubber Joint etc. Flexible pipe rubber coupling, is composed of inner layer, Nylon cord fabric enhancement layer,rubber sphere and metal flange. It has the characteristics of high pressure resistance, good flexiblity, big displacement, balance pipeline deviation, absorbing vibration, good effect to reduce noise, easy installation. Product Function: unique design, simple structure and good sealing performance, flexible rubber expansion joint completely solve the pipeline displacement problems caused by thermal expansion and contraction, as well as mechanical and pipe vibration.  Bellow Expansion Joint provide a wide range of rubber support with a reinforcement that depends on the pressure required. These types of elastomeric Rubber Bellow Joint isolate noise and vibration. When it comes to damage caused by vibration and expansion, each rubber expansion joint protects pipe systems by avoiding.
