Alumina ceramic is known for its excellent wear resistance, high-temperature resistance, and corrosion resistance, making it suitable for various industrial applications.
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.
High Hardness and Wear Resistance: With a Rockwell hardness of ≥90 HRA, these sleeves offer excellent resistance to abrasion, ensuring durability in demanding environments.
High-Temperature Stability: Capable of operating at temperatures up to 1650°C, they maintain structural integrity under extreme heat.
Corrosion Resistance: Alumina ceramics exhibit excellent resistance to chemical aggression, making them ideal for corrosive environments.
Electrical Insulation: They possess superior dielectric properties, suitable for electrical and electronic applications.

Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.
Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.
The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.
Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.
The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
