2: Ceramic tube pipe advantages :
  • High hardness 
  • Superior abrasion  
  • Corrosion and chemical resistance 
  • Light weight 
  • Low maintenance cost: Super wear-resistance reduce the maintenance frequency and also the maintenance cost.
  • Good fluidity : Smooth surface ensure the free flow of material without  blocking
