3. Product Characteristics
This product takes advantages of high flexibility and high air impermeability andmedium resistance of rubber as well as compliance and heat resistance of glass—fabric and is prepared at both ends with metal spool and flange in connection with wind machine and air duct ,which can compensate the thermal expansion by the operation of air duct and multidirections displacement. For better compliance of rubber and fabric and good sound absorption and vibration isolation, the noise and vibration passage can be reduced effectively in the operation of boiler, wind machine and air current. Because the main materials are rubber or fabric and fiber heat preservation materials of light weight without thrust in reverse and in no need of pipe supporting seat, a lot of materials are used so it has good heat resistance and corrosion resistance. In addition, rubber has better air impermeability absolutely without leakage and with lower price than metal compensator and import products.
