Alumina wear-resistant tile-lined pipes and ceramic plates/sheets are advanced solutions designed for industries that face extreme abrasion, corrosion, and high-temperature environments. By lining steel pipes and structural components with high-purity Alumina ceramics, companies benefit from significantly extended service life, reduced maintenance costs, and improved efficiency.

Key Performance Advantages

Compared to ordinary steel pipes or solid Ceramic pipes, the performance characteristics of alumina wear-resistant Ceramic patch lined pipes are more suited to the needs of industrial wear-resistant applications:

1.Extreme Wear Resistance

Alumina ceramic patch lined pipes have a Rockwell hardness of up to HRA85-90 (Mohs hardness 9.0, second only to diamond), andtheir wear resistance is 20-30 times that of manganese steel and 5-8 times that of cast stone pipes. For example, when conveying pulverized coal in the thermal power industry, their service life can reach 8-12 times that of ordinary carbon steel pipes, with annual wear ≤0.3mm. 

2.Wide Temperature Range and Corrosion Resistance

3.High-Temperature Resistance: Conventional models can operate for extended periods from -60°C to 400°C. Models with special high-temperature adhesives can withstand temperatures exceeding 600°C (e.g., high-temperature slag conveying in the metallurgical industry).

Corrosion Resistance: Ceramics are neutral materials, resistant to corrosion by sulfuric acid (concentration ≤ 98%), hydrochloric acid (concentration ≤ 30%), strong alkalis (NaOH concentration ≤ 50%), and most industrial slurries. They can replace stainless steel pipes in chemical desulfurization slurry pipelines, extending their service life by more than five times.

4.Impact-Resistant and Anti-Slip Design

5.The patch features a "chamfered splicing" or "interlocking groove" structure to prevent edge peeling caused by material erosion.

Some products incorporate an elastic resin into the adhesive layer to absorb material impact (impact strength ≥ 5kJ/m²), making them particularly suitable for conveying high-hardness particles (such as ores and slag). 7.
