Thermocouple Tubes
Thermocouple Protection Tubes are the structural refractory or metallic sheaths that protect thermocouple sensing elements from the mechanical, chemical, and thermal damage of direct industrial process exposure. Without adequate protection, thermocouple elements are rapidly destroyed by oxidizing atmospheres, molten metal splash, slag attack, and mechanical impact — leading to frequent sensor replacement and process measurement gaps. Imperial World Trade supplies thermocouple protection tubes in a comprehensive range of ceramic, silicon carbide, and high-temperature alloy materials for every industrial furnace and process application.
- Alumina (Al₂O₃) Tubes: High-purity ceramic tubes for oxidizing and neutral atmosphere furnaces up to 1,800°C; excellent chemical resistance and gas tightness.
- Siln Carbide (SiC) Tubesico: Superior thermal shock resistance for applications involving rapid temperature cycling or direct flame impingement up to 1,650°C.
- Mullite Tubes: Balanced thermal shock resistance and chemical stability for general-purpose furnace temperature measurement up to 1,600°C.
- Recrystallized Alumina (RCA) Tubes: Ultra-high purity, gas-tight tubes for the most demanding high-temperature measurement applications in clean atmosphere furnaces.
- Alloy Steel Sheaths: Inconel 600, 601, and 310SS metallic protection tubes for moderate temperature applications with high mechanical impact exposure.
- Custom Lengths & Diameters: Available in standard and custom dimensions to match existing thermocouple well and insertion depth requirements.
Imperial World Trade supplies thermocouple protection tubes with full material grade certification and dimensional inspection, ensuring the correct tube specification for your specific furnace atmosphere, temperature, and mechanical exposure conditions.
