Ceramic lined pipes for abrasive applications

Applications:

Since ceramics have excellent hardness and strength, FUVALVE ceramic lined pipes are widely used in many high

corrosive and abrasive transmission systems for coal fired power plant, steel plant, mining, chemical industry,

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
