FAQ

CAS No. : 1344-28-1

 

Alumina ceramic balls, manufactured according to standards such as GB, JIS, and API, exhibit exceptional wear resistance and corrosion resistance due to the properties of structural ceramics, including high-temperature resistance, wear resistance, corrosion resistance, and high hardness. They are widely used in fields such as petrochemicals, mining and metallurgy, power plants, medical equipment, and papermaking.

 

Product Characteristics

  • High wear resistance, corrosion resistance, and erosion resistance, coupled with excellent thermal insulation and low thermal expansion.
  • The balls are manufactured using advanced grinding equipment and processes, ensuring high roundness precision and excellent surface quality. After lapping with the valve seat, they achieve outstanding sealing performance.
  • It overcomes the drawbacks of metal hard-seal ball valves, such as leakage, high torque requirements, and corrosion-prone sealing surfaces.
  • The excellent wear resistance of ceramic ensures this product's exceptional durability, high reliability, and extended service life, lasting 2 to 4 times longer than titanium alloy valves and Monel valves.
  • For highly abrasive particulate media or corrosive media containing soft particles, alumina ceramic balls offer unparalleled advantages with their exceptional wear resistance and corrosion resistance.
