Advantages of Alumina Ceramic Tubes/Pipes
Alumina ceramic tubes have become an ideal choice in scenarios with requirements for high temperature resistance, corrosion resistance, and high purity, thanks to their triple advantages of "high temperature resistance + corrosion resistance + structural functionalization". Especially in fields such as new energy and high-end manufacturing, their performance can significantly improve production efficiency, product quality, and equipment reliability.
Applications of Alumina Ceramic Tubes/Pipes
1. Alumina ceramic tubesare used as material conveying tubes for calcining furnaces, protective casing tubes inside sintering furnaces, and insulating support tubes for hydrogen energy electrolyzers.
2. Alumina ceramic tubes is used as a gas distribution pipe for high-temperature kilns, a flow guiding pipe for molten metal, and a protective pipe for thermocouples in metal heat treatment furnaces.
3. Alumina ceramic tubes are used as catalyst conveying tubes for catalytic cracking units and high-temperature and corrosion-resistant exhaust pipes for waste gas treatment equipment.

Factory Equipment
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.
