Design Features

Custom-made zirconia ceramic profiled tubes, also known as industrial ceramic threaded connection tubes, showcase the versatility of 

zirconia ceramics in industrial applications requiring wear resistance, high temperature resistance, and chemical stability.

High Wear Resistance and High Fracture Toughness

Zirconium oxide ceramics possess a fracture toughness of up to 9 MPa^1/2, combined with its high hardness (Vickers hardness 

of 11.5 GPa), enabling these ceramic tubes to perform exceptionally well in environments subjected to mechanical stress and severe wear, 

maintaining long-term structural integrity.

Precision Thread Design

The precision machining of the threaded portion ensures a seamless fit with mechanical systems, providing stable connections and excellent 

sealing performance, suitable for high-pressure and high-temperature applications.

Excellent Thermal Stability

The coefficient of thermal expansion of zirconia ceramics is 9.6 × 10^-6/℃, combined with its thermal conductivity of 2.5 W/(m·K), 

providing excellent thermal stability. This allows these tubes to maintain performance even at high temperatures, making them suitable for 

thermal management systems.

Smooth Surface Treatment

Fine surface treatment technology results in a smooth ceramic tube surface, reducing hydrodynamic friction and improving system efficiency, 

especially in fluid transport and handling applications.

Customized Sizes and Shapes

Various complex shapes and sizes can be customized to meet specific mechanical and hydrodynamic requirements, enhancing the overall 

performance and adaptability of the equipment.

Application areas

Chemical Processing Equipment

Due to their strong resistance to chemical corrosion, zirconia ceramic tubes are particularly suitable for use in chemical reaction and 

processing equipment for conveying corrosive chemicals.

High-Temperature Industrial Applications

For example, in furnace tubes and heat exchangers, zirconia ceramics can withstand thermal shock up to 250°C, ensuring safe operation at 

high temperatures.

Electrical Insulation Applications

With high electrical insulation strength (greater than 10 kV/mm), they are suitable for high-voltage environments requiring electrical 

insulation.
