Applications:
Since ceramics material have high hardness and excellent strength, FUVALVE developed Ceramic Y Diverters, which are widely used in most of the high corrosive and abrasive transmission systems especially for coal fired power plants, steel plants, mining, chemical industry, petro-chemical, polysilicon and metallurgy.
The following listed are some typical medium in which Ceramic Lined Y Diverters have been proved to have good performance.
Coal powder
Silicon powder
Fly ash
Mining slurry
Mining Slag
Coal washing
Strong acid slurry
Paper making Slurry
