SiC Heat Exchange Tube
high performance silicon carbide ceramic heat exchanger possess high strength, high temperature resistance, high thermal conductivity and excellent acid or alkali corrosion resistance. It is mainly used in electric power, iron and steel, metallurgy, chemical, pharmaceutical, textile and other industrial fields. It is especially suitable for the harsh working conditions such as high temperature, high pressure, acid and alkali corrosion, high speed airflow, particle abrasion and etc.

1、High Thermal Conductivity

  • Much higher thermal conductivity than other corrosion resistant material.
  • Less space and smaller size.
  • Lower cost.

    •  


    2、Outstanding Corrosion Resistance


    • High performance of corrosion, oxidation and erosion resistance.
    • Endure high concentration of sulfuric acid, nitric acid, phosphoric acid, mixed acid, alkali, and oxidant.
    • The only hydrofluoric acid corrosion resistant ceramic material.
    • Long working life.
