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 (far exceeding the HV200-300 hardness of ordinary steel). A special adhesive bonds the ceramic patch tightly to the inner wall of metal pipes, such as Q235 carbon steel and stainless steel. Available in diameters from DN50 to DN2000, the product can be customized to meet industrial needs with various specifications, including straight pipes, elbows, tees, and reducers.
| Specification | Outer diameter | Inside diameter | Wall thickness | Steel pipe thick |
| DN80 | 112~132 | 80 | 10~14 | 6~12 |
| DN100 | 132~152 | 100 | 10~14 | 6~12 |
| DN150 | 182~202 | 150 | 10~14 | 6~12 |
| DN200 | 236~264 | 200 | 10~20 | 6~12 |
| DN300 | 336~364 | 300 | 10~20 | 6~12 |
| DN600 | 642~684 | 600 | 15~30 | 6~12 |

Service Life Extended 5-10 Times. Alumina ceramics offer 20 times the wear resistance of ordinary seamless steel pipes. Service life can be extended to 3-5 years for highly abrasive media.
Exceptional chemical stability, withstanding corrosion from acidic, alkaline, and salt solutions (pH 1-14) and high-temperature flue gases (≤800°C).
Smooth surface with a friction coefficient of only 0.15-0.2. Energy consumption is reduced by 15%-20% for the same conveying volume.
High-strength adhesive with shear strength >15MPa. Impact-resistant treatment prevents ceramic fallout during shock and vibration.
