Extruded Alumina Ceramic Tubes/Pipes
My factory looking for distributors.
Advantages of alumina ceramic tubes/pipes
Using high-purity alumina raw materials can effectively reduce the adverse effects of impurities on the performance of ceramics. Adding specific additives can improve the performance of alumina ceramics.
Isostatic pressing can make the density of the green body uniform, reduce internal stress concentration, and improve the strength of alumina ceramic tubes at high temperatures. Injection molding can produce alumina ceramic tubes with complex shapes to meet the needs of different detection and analysis scenarios.
Applications of alumina ceramic tubes/pipes
Mining industry: Alumina ceramic tubes are used for conveying abrasive materials such as iron ore powder and tailings slurry.
Thermal power generation: Alumina ceramic tubes are applied to coal powder pipelines and ash removal systems.
Chemical industry: Alumina ceramic tubes are used for pipelines transporting corrosive media (such as acids and alkalis).
Metallurgical industry: Alumina ceramic tubes are utilized in blast furnace coal injection and steel slag treatment systems.

Our factory
Established in May 2000, Jinzhou Yunxing Industrial Ceramics Co., Ltd. originated as Jinzhou Yunxing Technology Development Co., Ltd. Initially located within the enterprise incubator factory on Yulu Street, High-Tech District, our company relocated in April 2002 to a leased industrial site owned by the Agricultural, Industrial, and Commercial Corporation in Taihe District. By the end of 2006, to accommodate expansion, we moved to No. 9 Weimin Road, Fantun Village, Yingpan Town, Taihe District, and subsequently adopted our current name. In December 2023, we transitioned to our new premises at No. 5 Xinggong Road,Taihe District （ Da Xu Industrial Park, Yingpan Town, ）.
Our workforce comprises over 70 dedicated employees, including 1 senior engineer and 5 engineers and technicians. We specialize in the production of industrial ceramics with a 99.3% alumina content, catering primarily to industries such as instrumentation temperature measurement, industrial furnaces, university laboratories and testing of inorganic non-metallic materials. In 2023, we achieved a sales revenue of 15.78 million yuan and contributed 1.88 million yuan in taxes, amounting to a cumulative tax contribution of 20.13 million yuan over the years.
The company's main products are: alumina ceramic tubes, alumina ceramic crucibles, alumina ceramic rods, alumina ceramic boats, alumina ceramic plates, alumina ceramic parts, etc.
