This product takes advantages of high
flexibility and high air impermeability and medium 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.
