Alumina Ceramic Pipe
My factory looking for distributors.
Advantages of alumina ceramic pipe
1. Alumina ceramic pipe are made of high-purity aluminum oxide and are suitable for extreme environments.
2. Alumina ceramic pipes have high temperature resistance, corrosion resistance, and wear resistance.
3. The excellent mechanical strength and thermal stability of alumina ceramic pipes ensure extended service life and reduced maintenance costs.
4. From conveying abrasives to corrosive fluids, alumina ceramic pipes provide reliable performance, improving operational efficiency and productivity.
Application of alumina ceramic pipe
1. Alumina ceramic pipes are composed of high-purity alumina and are widely used in industries such as metallurgy, mining, chemical processing, and power generation.
2. In the metallurgical process, alumina ceramic pipes play a crucial role in conveying molten metal and abrasive slurry.
3. In mining operations, alumina ceramic pipes are used to transport abrasives such as ores, minerals, and tailings.
4. Chemical processing plants rely on alumina ceramic pipes to treat corrosive fluids and chemicals.
5. The application of alumina ceramic pipes has surpassed traditional industry and extended to emerging fields such as renewable energy and environmental protection.
6. The widespread adoption of alumina ceramic pipes is attributed to their excellent performance, which helps improve the productivity and profitability of industrial enterprises.
We only make high purity alumina ceramics
1. High-purity alumina content 99.3% -99.5%, other alumina ceramics 92% -99%.
2. The color of high purity alumina product is milky white, and other products are pink or white. The higher the purity, the more transparent the color.
3. Alumina is a refractory material, the higher the purity, the better the refractory effect
4. After high-purity alumina ceramics are fired and cooled in a 1800-degree high-temperature kiln, the products are not easy to break when they encounter high temperatures. Other ceramics are fired at 1500 ℃ ~ 1800 ℃.
5. The volume density of high-purity alumina> 3.92 g / cm3 has a smooth surface and is not easily corroded by chemicals. The bulk density of other ceramics is> 3.70 g / cm3 ~> 3.85 g / cm3.
6. High purity alumina has good hardness and good wear resistance.
7. High purity alumina products have a longer service life.

Our factory
Slip casting moulding: Inject the prepared slurry into the gypsum mold and let it stand for a period of time to allow the gypsum mold to absorb moisture. The slurry forms a uniform body on the inner wall of the mold.
Injection moulding: Inject a slurry containing paraffin into a metal mold at a certain temperature and pressure, and after the body cools and solidifies, perform demolding to prepare ceramic bodies.
Extrusion moulding: Suitable for long tube products, the powder is extruded into shape through an extruder.
FAQ
Q1. What information should we supply to get a quote?
A1. Please offer the specification of ceramic tube, such as shape, dimension, quantity, application etc.
Q2. Can alumina ceramic tubes be reused after use?
A2. Yes, alumina ceramic tubes can be reused after use, provided they are undamaged and free from contamination. Proper cleaning and inspection are necessary to ensure their suitability for subsequent applications.
