KNIGHT-WARE™ Acid Proof Brick

Our KNIGHT-WARE® Fireclay Acid-Proof Brick sets the global standard in corrosion proof brick lining. We design and manufacture KNIGHT-WARE™ Fireclay Acid-Proof Brick in simple and complex geometric shapes, providing the most custom and adaptable shapes and sizes for today's market. Our brick manufacturing capabilities allow us to produce a lining custom designed to fir vessels in service today as well as those that may be in service in the future. All KNIGHT-WARE™ Fireclay Acid-Proof Brick are true refractory and will maintain their corrosion-resistant qualities in high temperature environments. Our bricks conform to ASTM 279C specifications and are available in various formulas, sizes and shapes to service multiple application designs.

KNIGHT-WARE® Fireclay Acid Proof Brick – True refractory and corrosion-resistant in high temperature environments.

  • Type II - Chemical resistant masonry for process vessel lining
    • P-II - Pressed
    • E-II - Extruded
  • Type III - Pressed brick with low water and acid solubility.
    • AP302 - High alumina and density with strong abrasion resistance.
    • PV33P - Pressure vessel applications subject to thermal shock and spalling
    • WR - Abrasion resistant for agitating vessels which process acidic abrasive slurry
    • HD - High density porcelain with low porosity
  • CORESITE™- Inorganic material with alkali-resistance within pH range of 5 to 14
  • CARBON - Metallurgical coke with high degree of chemical resistance provides excellent service when subjected to extreme thermal shock

  • GLASSROCK™ - Open cell-type, pure fused silica foam with high thermal insulation and shock properties
