Alumina ceramic tube is made of 99% high purity alumina ceramic material.Download PDF
According to customer requirements, we can provide different high-purity alumina ceramic tubes, such as: Alumina ceramic(Al2O3):95%;96%;97%;98%;99%;99.5%:99.7%;99.9%…etc.
The High heat temperature alumina tube have a excellent high heat temperature resistant ability. High heat temperature alumina tube can be used under 1800℃ high temperature environment.Coefficient of thermal expansion up to 9* 10∧6 from 20°C- 1000°C. up to 2050°C Melting point.
Corrosion resistant for alumina tubes
Corrosion alumina tube material has excellent chemical stability under high temperature, it is not easy to oxidize, and Corrosion alumina tube has good corrosion resistance to acid, alkali and salt.
Aluminum(Al2O3) ceramic products are widely used because of it’s good wear resistance, such as power plant, mine, coal transportation, etc.
It has much longer lifespan than traditional steel pipe, which can help to reduce production cost greatly.
Sunny Steel can produce all kinds of alumina ceramic tube, elbow, ring, three way tube and cone, etc.
|Content of alumina (AL2O3)||≥99%|
|Rockwell Hardness||≥90 HRA|
|Compressive strength||≥2950 MPA|
|Volume wear||（p＝76N n=800 circle /m t＝30 min）≤0.0002g|
The main raw material of wear resistant ceramic ring is a special kind of ceramic with AL2O3 as the and the rare metal oxide as the flux, which is melted by high temperature at 1700 °C. The Ceramic Sleeves Lined Pipe as a whole part, and then assemble it into the steel pipe with our high-strength-temperature-resistant epoxy adhesive.
Recently 95% alumina ceramic sleeve lined pipes, elbows and T pipes have been largely applied in lithium battery material conveying system. The big diameter ceramic sleeve is always a big problem for the ceramic tube manufacturers since it’s very difficult to control the deformation rate of the ceramic sleeve after it’s sintering .Also It will also need an advanced and big isostatic pressing machine to do this .So it will not only express the company’s production capability ,but company’s technology. Right now, our factory have owned both advantages which are wear resistant ceramic pressing facilities and technologies.

Abrasion resistant pipe using steel skeleton packaging, and the two ends of the pipe with plastic head, to prevent dust and rain into the pipeline inside, to ensure the beauty of the product.
For different production environments, our company has developed a wear-resistant pipe for a variety of media, based on the temperature, wear and corrosion requirements of the field media, and for the initial application of the scene, our company to provide wear-resistant ceramic ring for the Lined composite straight pipe design to meet the on-site wear resistance, heat resistance and corrosion resistance requirements, in view of this program for the new design (formerly ceramic chip technology, there are many gaps, easy to wear).
After the ceramic ring in the pipe is installed and the thread is processed, the dirt outside the pipe is cleaned, and the outer surface of the pipe is treated with three layers of anticorrosive paint to meet the export requirements.
