Double Sphere Rubber Expansion Joint
Twin sphere rubber expansion joint
Double Ball Rubber Joint, is mainly the use of rubber unique properties, such as high flexibility, high air tightness, chemical resistance and radiation resistance, high strength, strong cold stability bias ply polyester composite Hou contrast, high pressure, high temperature molded cross-linked internal high density, can bear high pressure, high elastic deformation effect.
Constructed of neoprene and nylon (other materials are available see charts below), the spherical shape allows pressure to exert itself uniformly in all directions, thus reducing the force exerted on pipe lines and equipment. Bias-ply tire cord provides strength, a high safety factor, and low force to move. Precision molding provides a dense, uniform carcass.
Features
● Minimal axial dimensions
● Limited weight
● Low warping forces
● High-resistance to work
● High-capacity acoustic damping
