Applications:

Since ceramics have excellent hardness and strength, FUVALVE developes ceramic lined Elbows, which are

widely used in many highly corrosive and abrasive transmission systems especially for coal fired power plants,

steel plants, mining, الصناعة الكيميائية, petro-chemical, polysilicon and metallurgy.

The following working conditions are some typical medium in which ceramic lined elbows have been proved to have

good performance.

  • Coal powder
  • Silicon powder
  • Fly ash
  • Mining slurry
  • Mining Slag
  • غسل الفحم
  • Strong acid slurry
  • Paper making Slurry
