أنابيب سيراميك مبطنة للتطبيقات الكاشطة
Applications:
Since ceramics have excellent hardness and strength, فوفالف ceramic lined pipes are widely used in many high
corrosive and abrasive transmission systems for coal fired power plant, steel plant, mining, الصناعة الكيميائية,
petro-chemical and metallurgy.
The following working conditions are some typical medium in which ceramic lined pipes have been proved to have good performance.
Coal powder
Fly ash
Mining slurry
Mining Slag
Coal washing
Strong acid slurry
Paper making Slurry
