Wear Resistant Ceramic Tube

- Dec 27, 2019-

Alumina ceramics lined with pipes have become one of the most widely used wear-resistant materials due to their high abrasion resistance, high hardness, oxidation resistance, good corrosion resistance and extremely high and low temperature resistance properties, occupying the world's special ceramic market The share (abrasion resistant material) is about 80%.

Good abrasion resistance

Because the ceramic composite pipe is lined with ceramic (AL2O3), the Mohs hardness can reach 9.0 equivalent to HRC85 or higher. Therefore, it has high wear resistance to the abrasive media transported by metallurgy, power, mining, coal and other industries. It has been confirmed by industrial operation that its wear life is ten times or even dozens of times that of quenched steel.

Low running resistance

Because the inner surface of the ceramic composite pipe is smooth and never rusted, there is no convex spiral line on the inner surface of the seamless steel pipe. Low running resistance can reduce running costs.

Resistant to corrosion and scale

The lined alumina ceramic layer is neutral. Therefore, it is resistant to acid and alkali and seawater corrosion, and has anti-scaling properties.

Temperature resistance

Therefore, the composite pipe can operate normally for a long time in the temperature range of -50 to 700 ° C. The linear expansion coefficient of the material is 6-8 × 10-6 / 0C, which is about 1/2 of the steel pipe. The material has good thermal stability.

Low construction cost

Ceramic composite pipe is light weight and affordable. 50% lighter than cast stone pipes of the same inside diameter; 20-30% lighter than abrasion-resistant alloy pipes, and good wear resistance and corrosion resistance, because of long service life, and thus support hanger costs, handling costs, installation costs Reduced operating costs. After comparing the engineering budget and actual engineering of the relevant design institute and construction unit, the project cost of this pipe is equivalent to that of cast stone. Compared with the wear-resistant alloy pipe, the project cost is reduced by about 20%.

Easy installation and construction

Because the tube is lightweight and has good welding performance. Therefore, welding, flange, quick connection and other methods can be adopted, which is convenient for construction and installation, and can reduce installation costs.
