Customized high purity both end open 95% 99% alumina insulation ceramics tube

A both-end open alumina tube is a cylindrical structure made from alumina (aluminum oxide, Al₂O₃)

with both ends open, allowing for the passage of gases, liquids, or other materials. These tubes are widely

used in high-temperature and chemically aggressive environments due to alumina's excellent thermal,

mechanical, and chemical properties.

We can do OEM and OBM according to your drawing and requires​:​​​​​​

Key Features of Both-End Open Alumina Tubes:

     1.High-Temperature Resistance: Can withstand temperatures up to 1700°C or higher, depending on

     the alumina purity.

     2.Chemical Inertness: Resistant to most acids, alkalis, and corrosive gases.

     3.Electrical Insulation: Excellent electrical insulator, making it suitable for applications requiring electrical isolation.

     4.Mechanical Strength: High hardness and durability, resistant to wear and mechanical stress.

     5.Thermal Shock Resistance: Can endure rapid temperature changes, though this depends on the alumina grade 

     and wall thickness.

     6.Gas/Liquid Permeability: Both ends are open, allowing for the flow of gases, liquids, or other materials through the tube.

Types of Both-End Open Alumina Tubes

Standard Purity (e.g., 95% Alumina): Suitable for general-purpose applications.

High Purity (e.g., 99.5% or 99.8% Alumina): Offers better thermal and chemical resistance, ideal for demanding 

applications like semiconductor manufacturing.

Translucent or Transparent Alumina: Used in specialized applications where light transmission is required.

Key Specifications to Consider

Inner Diameter (ID) and Outer Diameter (OD): Determines the flow capacity and mechanical strength.

Length: Custom lengths are available depending on the application.

Wall Thickness: Thicker walls provide greater mechanical strength but may reduce thermal shock resistance.

Surface Finish: Smooth or polished surfaces may be required for specific applications.

Purity: Higher purity alumina offers better performance in extreme conditions.

Advantages of Both-End Open Alumina Tubes

Excellent thermal stability and resistance to thermal shock.

Chemically inert, making them suitable for corrosive environments.

High mechanical strength and durability.

Versatile for use in a wide range of industries and applications.
