Characteristics of ceramic wear-resistant tile

Characteristics of ceramic wear-resistant tile

1. Good wear resistance

  The ceramic is corundum ceramic (a-AL2O3), the Mohs hardness can reach 9.0, which is equivalent to above HRC90. Therefore, it has high wear resistance to the abrasive media transported by metallurgy, electric power, mining, coal and other industries. Proved by industrial operation: its wear resistance life is ten times or even dozens of times that of quenched steel.

2. Low running resistance

  Because the inner surface is smooth and never corroded, there is no convex spiral on the inner surface of seamless steel pipe. The internal surface roughness and clean water resistance characteristics of the relevant testing units have been tested, and the internal surface smoothness is better than that of any metal pipeline, and the clean resistance coefficient is 0.0193, which is slightly lower than that of seamless pipes. Therefore, the tube has the characteristics of low running resistance, which can reduce the running cost.

3. Anti-corrosion and anti-scaling

  Because the ceramic layer is (a-AL2O3), it is neutral in nature. Therefore, it has acid and alkali resistance and seawater corrosion resistance, and at the same time has anti-scaling properties.

4. Good temperature resistance and heat resistance

   Because of this corundum ceramic (a-AL2O3), it is a single stable crystalline structure. Therefore, the composite pipe can operate normally in the temperature range of -50-700℃ for a long time. The coefficient of linear expansion of the material is 6-8×10-6/0C, which is about 1/2 of that of the steel pipe. The material has good thermal stability.

5. Low project cost

  Ceramic lining is light in weight and reasonable in price. It is 50% lighter than cast stone with the same inner diameter; 20-30% lighter than wear-resistant alloy pipe, and has good wear resistance and corrosion resistance. Because of its long service life, it will support and hanger costs, handling costs, installation costs and operation Cost reduction. Comparing the project budget and actual project by the relevant design institutes and construction units, the project cost of the pipe is equivalent to that of cast stone. Compared with the wear-resistant alloy pipe, the project cost is reduced by about 20%.

6. Convenient installation and construction

  Because the tube is light in weight and has good welding performance. Therefore, welding, flanges, quick coupling, etc. can be used, which is convenient for construction and installation and can reduce installation costs.
