Tired of fragile, short-lived thermocouple tubes that crack and corrode easily in high-temperature and corrosive industrial environments? Our NSiC thermocouple protection tubes are engineered for harsh industrial conditions, delivering stable performance, excellent durability and lower maintenance costs!

Excellent high-temperature structural stability and oxidation resistance. Stable continuous operation up to 1450℃, no deformation, softening or peeling. Ideal for industrial furnaces, heat treatment equipment and high-temperature production lines.
High chemical inertness and dense structure effectively resist acid, alkali, flue gas and sulfide corrosion. Perfect for molten aluminum, zinc, magnesium and other non-ferrous metal smelting scenarios, no adhesion or contamination to molten liquid.
Adopts professional slip casting and secondary firing technology, featuring uniform density, high hardness and strong impact resistance. Withstands frequent vibration, material erosion and continuous industrial operation. More cost-effective than isostatic pressed pure silicon nitride tubes, perfectly balancing quality and economy for mass industrial applications.
Low thermal expansion coefficient and stable thermal conductivity. Resists rapid temperature changes and alternating hot/cold cycles without cracking or peeling, greatly reducing replacement frequency.
Uniform heat conduction ensures fast temperature response and precise measurement, effectively stabilizing industrial temperature control and improving production efficiency.

Custom large-diameter electric heating casing tubes tailored for molten zinc and aluminum smelting. Dense and uniform tube wall, stable heating performance, no leakage or electric leakage. Fully compatible with high-power heating equipment, perfect for large-scale industrial smelting production!
Application Scenarios:Metallurgy, non-ferrous metal smelting, ceramic furnace, chemical high-temperature equipment, industrial heat treatment furnaces, molten metal processing and more.
