    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.

     Double Ball Expansion Rubber Joints is from the inside layer, enhanced multi-layer plastic scraper nylon cord, rubber outer layer composite tubes. Depending on the medium used rubber material is different, there are natural rubber, styrene-butadiene rubber, butyl rubber, nitrile rubber, EPDM rubber, neoprene, silicone rubber, fluorine rubber and so on. Respectively, with heat, acid, alkali, corrosion resistance, abrasion resistance, oil and other functions.

    applications in a wide range of industries, including:

    •     Power Generation

    •     Pulp and Paper

    •     Chemical Processing

    •     Water/Waste Water

    •     Marine

    •     Mining

    •     Heating, Ventilating, and Air Conditioning

    Expansion Joints offer superior performance, reliability, and service life. This in turn improves plant safety, increases the mechanical integrity of equipment, and allows customers to gain a competitive advantage in the marketplace.
