氧化铝热电偶保护管
Primarily used in industrial furnaces, metal heat treatment, powder metallurgy furnaces, ceramic sintering furnaces, and similar applications.
Silicon Carbide Thermocouple Protection Tube
Used for molten steel and iron temperature measurement, waste incinerators, and new energy material sintering.
Silicon Nitride Thermocouple Protection Tube
Used for molten aluminum temperature measurement, non-ferrous metal smelting, aluminum alloy manufacturing, etc.
Alumina Insulating Tube
Insulating tubes are mainly used for internal insulation of heating elements (heating tubes), internal insulation of thermocouples (double-hole/multi-hole tubes), and power equipment.
Zirconia Sleeve
It can be used for ultra-high temperature measurements (higher than alumina), plasma equipment, and high-radiation processes, and is not prone to cracking.
Alumina Sleeve
It can be used in various industrial furnaces, heat treatment furnaces, sintering furnaces, high-temperature laboratory equipment, ceramics, glass and other industries.
Silicon Nitride Sleeve
It can be used for temperature measurement of molten aluminum, smelting of non-ferrous metals such as aluminum and copper, and in the aluminum die-casting industry.
Applications of Ceramic Protective Pipes
Used for electrical insulation protection
It is mainly used for various electrical insulation applications, isolating conductors, and preventing short circuits or leakage. Common applications include internal insulation protection for heating elements and thermocouples. It is available in single-hole, double-hole, and multi-hole structures.
Used for thermocouple and RTD protection.
It is mainly used to protect thermocouples from damage caused by high temperature, corrosion or mechanical damage, such as in industrial furnaces, heat treatment furnaces, sintering furnaces and other equipment, effectively ensuring and extending the life of thermocouples.
Common materials include alumina, silicon nitride, silicon carbide, and mullite.
Outer Protection Tube
Primarily used as an outer protective layer to isolate internal components from harsh environments. It is mainly used in highly corrosive and abrasive applications, such as in the chemical, environmental protection, and powder transportation industries. It primarily utilizes silicon carbide, a material known for its high wear and corrosion resistance.

常见问题解答
Which material is best suited for thermocouple protection tubes?
This depends on your intended use, such as temperature, environmental chemistry, thermal cycling, fluid flow, and key factors related to the particles.
Alumina is more economical and versatile, silicon nitride is better suited for environments with drastic temperature variations, while silicon carbide is better suited for more extreme environments.
Can silicon carbide tubes be used with platinum wire thermocouples?
Absolutely, GORGEOUS CERAMICS would recommend using an inner alumina protective tube (with one end closed).
What types of protective tubing do you provide?
We offer ceramic insulating tubes, thermocouple ceramic protective tubes, protective sleeves, and other products made from various materials.
