Alumina ceramic patch wear-resistant pipe is a composite pipe product developed specifically to address the wear challenges faced by industrial pipes. It utilizes a dual-layer composite structure consisting of a high-strength ceramic patch and a metal matrix. The core wear-resistant layer is made of alumina ceramic (AlO2) with a purity exceeding 92%, sintered at high temperatures.
The ceramic patch has a hardness of HV1100-1300, bonded tightly to the inner wall of metal pipes such as Q235 carbon steel and stainless steel. Available in diameters from DN50 to DN2000.

| DN80 | 112~132 | 80 | 10~14 | 6~12 |
| DN100 | 132~152 | 100 | 10~14 | 6~12 |
| DN200 | 236~264 | 200 | 10~20 | 6~12 |
| DN500 | 542~584 | 500 | 15~30 | 6~12 |
| DN1000 | 1046~1088 | 1000 | 15~30 | 8~14 |
| DN2000 | 2046~2088 | 2000 | 15~30 | 8~14 |

Alumina ceramics offer 20 times the wear resistance of ordinary seamless steel pipes. Service life can be extended from 3-6 months to 3-5 years in highly abrasive media environments.
Withstanding corrosion from acidic, alkaline, and salt solutions (pH 1-14) and high-temperature flue gases (≤800°C).
Smooth surface with a low coefficient of friction (0.15-0.2), reducing energy consumption by 15%-20%.
High-strength adhesive with shear strength >15MPa prevents ceramic fallout even under shock and vibration.
