Product Description
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.

Key Features
1. Ultra-Wear-Resistant
Alumina ceramics offer 20 times the wear resistance of ordinary seamless steel pipes and 5 times that of cast stone pipes. Service life can be extended from 3-6 months to 3-5 years.
2. Corrosion-Resistant
Withstands corrosion from acidic, alkaline, and salt solutions (pH 1-14) and high-temperature flue gases up to 800°C.
3. Low Resistance and High Efficiency
Smooth surface with a low friction coefficient (0.15-0.2), reducing energy consumption by 15%-20%.
4. Safe and Reliable
High-strength adhesive ensures shear strength >15MPa, preventing ceramic fallout during media conveyance.
Frequently Asked Questions
What is the hardness of the alumina ceramic lining?
The ceramic patch has a Rockwell hardness of HRA80-90 (HV1100-1300), which is nearly as hard as diamond and significantly harder than traditional steel.
How much can this pipe extend the service life of my system?
Depending on the abrasive media, it can extend the service life by 5-10 times compared to traditional alloy or manganese steel pipes.
What temperature range can these pipes handle?
The alumina ceramic material is stable and can withstand high-temperature flue gases up to 800°C.
Is the ceramic lining likely to fall off during high-impact use?
No, we use a high-strength, high-temperature-resistant adhesive with a shear strength of >15MPa and apply impact-resistant treatment to the joints.
Can you provide customized sizes?
Yes, we support customization for a wide range of specifications, from DN50 up to DN2000, including elbows, tees, and reducers.
In which industries are these pipes commonly used?
They are widely used in coal washing, steel plants, thermal power, chemical environmental protection, and cement industries.
