Description of Molybdenum Thermocouple Protection Tube
Molybdenum Thermocouple Protection Tube is made of molybdenum material after powder metallurgy processing. It has high melting point, high temperature resistance, corrosion resistance, oxidation resistance, wear resistance, good high temperature stability, environmental protection and durability, low cost, good conductivity, etc. Series advantages.
Molybdenum Thermocouple Protection Tube is mainly used to protect the working environment where various thermocouples and heating elements are in contact, protect the hot electrode from human or mechanical damage, avoid and prevent corrosion of the hot electrode by harmful media, so as to extend the service life and operational stability.
Molybdenum Thermocouple Protection Tube can be installed horizontally or vertically. During use, regular cleaning and maintenance are required, as well as long-term data monitoring to ensure measurement accuracy.
Features of Molybdenum Thermocouple Protection Tube
1. Ultra-High-Temperature Stability
With a melting point as high as 2623°C, it can operate in high-temperature environments ranging from 1600°C to 2000°C for extended periods (and can withstand 2300°C for short periods).
This outperforms ordinary stainless steel (maximum 1200°C) or ceramic protective tubes (which are prone to thermal shock cracking).
2. Excellent Thermal Shock Resistance
Molybdenum has excellent thermal conductivity (138 W/m·K), allowing it to quickly adapt to sudden temperature changes and reduce thermal stress cracking.
3. Corrosion and Oxidation Resistance
Inert/Reducing Environments: It performs excellently in hydrogen, argon, and vacuum.
Oxidizing Environments: It requires a coating (such as silicide) or an external ceramic coating (such as Al₂O₃) to prevent high-temperature oxidation.
4. High Mechanical Strength
Maintains high strength even at high temperatures and exhibits superior creep resistance compared to nickel-based alloys.
5. Vacuum Compatibility
Extremely low gas permeability makes it suitable for high-vacuum and semiconductor process equipment.

Advantages of Molybdenum Thermocouple Protection Tubes at a Glance
Superior performance at high temperatures
The thermocouple protection tubes made from molybdenum were designed for extremely high temperatures with a melting point over 3,000°F or 1,600°C. In such tubes, the thermal stability remains unparalleled, maintaining accuracy for temperature sensors where other materials cannot stand. Therefore, this material finds its essential use in industries related to steel manufacturing, semiconductor production, and testing in aerospace.
Excellent Mechanical Strength
With its intrinsic strength, even at high temperatures, molybdenum ensures our thermocouple protection tubes will perform reliably under stress. These tubes can resist the mechanical forces of high-pressure and high-temperature applications without deforming, further improving their durability and reliability.
Corrosion and Oxidation Resistant
Molybdenum is highly resistant to oxidation, which is very important in reducing wear and tear resulting from exposure to gases, chemicals, and extreme heat. This corrosion resistance allows our thermocouple protection tubes to function under harsh conditions, including the presence of molten metals, acidic gases, and other corrosive media.
Precision engineering ensures precise temperature sensing.
Accurately processed, our molybdenum protection tubes are formed and sized for specific thermocouple sensors. That would be impossible without the precision necessary to achieve good, precise temperature measurements in industrial process control.
