Description of Aluminium Oxide Tubes with Multiple Bores
Aluminium oxide tubes with multiple bores, fabricated from high-purity aluminium oxide (Al2O3), feature a structure with several parallel channels. This design results in a tensile strength ranging from 32 Kpsi to 36 Kpsi, thermal stability up to temperatures of 1 750 °C, and measurable resistance to wear and corrosion. The tubes provide electrical insulation suitable for high-voltage environments. Their chemical inertness ensures compatibility with a range of aggressive chemicals, thereby maintaining performance in demanding industrial settings. Consequently, they are employed for the protection of thermocouples, implementation in gas and liquid flow systems, and use in high-precision measurement devices.

Applications of Aluminium Oxide Tubes with Multiple Bores
1. Protection of thermocouples: Aluminium oxide tubes with multiple bores are employed to shield thermocouples in high-temperature environments. This practice maintains measurement accuracy and extends thermocouple service life.
2. Gas and liquid flow systems: These tubes are used in gas and liquid flow systems because they withstand high temperatures, corrosion, and wear. They are implemented in chemical processing and the petrochemical industry.
3. Electrical insulation: Owing to their measured electrical insulation properties and resistance to thermal and mechanical stress, they are utilised as insulators in high-voltage applications.
4. Analytical and laboratory equipment: Their design facilitates simultaneous tests or separation processes in challenging chemical environments. Instruments and laboratory apparatus incorporate these tubes for reliability in tests.
5. Furnaces: Aluminium oxide tubes with multiple bores are used in ovens and kilns to support and protect sensors and other components that face elevated temperatures.
6. Catalyst carriers: They serve as carriers in chemical reactions where a large surface area and thermal stability are required. The multiple bores permit efficient gas flow and maintain satisfactory reaction kinetics.
7. Medical and dental devices: They are incorporated in precision instruments and equipment in medical and dental applications that require biocompatibility, chemical inertness, and high strength.
8. Heat exchangers: They are integrated into heat exchanger systems where thermal conductivity and tolerance to temperature fluctuations meet design requirements.
9. Optical fibre protection: They protect optical fibres in high-temperature and corrosive environments, thereby preserving the integrity and performance of optical communication systems.
10. Aerospace and defence: These tubes are applied in components for aerospace and defence that require specified mechanical strength, thermal stability, and resistance to extreme conditions.
11. Chemical processing: Aluminium oxide tubes with multiple bores are used in chemical processing facilities for the transport and treatment of corrosive chemicals and gases.
12. Fuel cells: They are applied in fuel cells as separators and insulators, utilising temperature resistance and chemical stability.
