1. Product Performance: Base on the unique characteristics of rubber such as high elasticity , high air tightness, medium resistance, weathering resistance and radiation resistance, the product, with polyester cord characterized of high strength and high heat stability adopted for skew crossing and compound, is made under high pressure, high temperature molding and cross link. It owns higher density inside to bear higher pressure as well as ideal elastic deformation. 2. Product Application: 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 Product Advantages: High pressure, good elasticity. Large deformation displacement. Noise damping effect, flexible. Long service life. Can be widely used in hotels, factories, residential plumbing systems and recycled water pipes, sanitary pipes, chemical corrosion and frozen pipes etc.
