1, Product Information: Rubber expansion joints are flexible connectors fabricated of nature rubber or synthetic elastomers, steel ring and fabrics, and when necessary, metallic reinforcements provide stress relief in piping systems due to thermal and mechanical vibration and/or movements. ZHW® Rubber Expansion Joints provide relief from stresses caused by thermal expansion and contraction in pipelines. Movement is always experienced in piping systems due to varying ambient temperatures, differences in temperature of materials handled, and differences in composition. Expansion joints absorb this movement and eliminate the danger of buckling or pulling apart with the high replacement costs that would result. 2, Product Advantages: Zhonghaiwei® spherical flexible joint impress with their compensating and damping material properties. Excessive force, arising within the pipeline, is deflected by Zhonghaiwei® rubber expansion joints before this can be passed on to adjacent components. Our expertise, in designing and constructing rubber expansion joints, is reflected in their long service life and high operational reliability. This explains why Top5 of China power plants are equipped with Zhonghaiwei® spherical flexible joint. Zhonghaiwei® spherical flexible joint are made of high-quality rubber. They are used in industrial environments and in plant and process engineering, as well as in mechanical engineering, in the production of motors and the construction of industrial equipment, and even in shipbuilding. They have also found their way into building services engineering, environmental engineering and hydraulics. 3, Product Applications: For air conditioning, heating and ventilating systems in industrial buildings and vessels. Central and ancillary power generating stations in industrial buildings, factories, ships and off-shore applications Sewage disposal and water treatmentplant, pumps, etc. Process piping in pulp and paper plants Piping systems for chilled or hot water in industrial plants Cooling systems for power generation Feed water and draining lines for water works, sewage, sanitary piping systems etc. Oil lines for industrial plants, shipyards, phosphate plants etc. Potable water applications Food applications
