High alumina 95% Ceramic lined flexible natural rubber hose is ideal for use in highly wear resistance and corrosion resistance where conventional rubber hose, expansion joints, or bellows connections require frequent replacement. Also be used to isolate mechanical vibration or to connect non-stationary equipment.

It is widely used in thermal power plants, cement plants, ore dressing plant, chemical corrosion resistance, coal powder and the slurry delivery system, and also used for port and river dredging suction sand, concrete pump vehicle and so on.
