Design Features

Alumina ceramic flanges (also known as porous ceramic retaining rings) are specifically designed for industrial applications, combining the 

excellent mechanical properties, high-temperature resistance, and corrosion resistance of alumina, making them an ideal choice for extreme 

environments.

Porous and Grooved Design

This design enhances the flange's holding power, providing better sealing and connection stability, suitable for complex mechanical systems.

High Mechanical Strength

The high hardness of alumina (Vickers hardness up to 15.7 GPa) ensures durability and long-term stability under high load conditions.

Excellent High Temperature Resistance

Able to operate in environments up to 1650°C, suitable for high-temperature applications such as furnaces and heat exchange systems.

Outstanding Corrosion Resistance

Maintains stable performance even after chemical treatment or exposure to corrosive environments, preventing material degradation.

Application areas

Chemical Processing Equipment

Used in equipment handling strong acids, strong alkalis, or other corrosive substances to ensure seals and mechanical integrity.

High-Temperature Industrial Systems

Used as critical connection and sealing components in heat treatment facilities, steel mills, and other environments requiring high 

temperatures.

Power Generation and Thermal Energy Facilities

Used as sealing elements in high-temperature and high-pressure environments to protect critical fluid control systems.

Aerospace and Automotive Industries

Used in engines and other critical systems requiring extremely high temperature and pressure resistance.
