1. High strength, good thermal conductivity, thin tube wall (only a few millimeters), so the product is very sensitive to temperature changes;
2. Good corrosion resistance, completely unaffected by erosion;
3. High temperature resistance, will not melt at high temperature, no pollution to metal liquid;
4. The surface of the protection tube does not adhere to slag and is very easy to maintain.
Silicon nitride thermocouple protection tube can be used to protect thermocouples that measure liquid aluminum temperature, and also used in nonferrous gold smelting industry.
We are committed to delivering optimal silicon nitride ceramic thermocouple protection tube tailored to your exact specifications. Our dedicated team ensures meticulous adherence to your instructions, striving to exceed customer expectations. Additionally, we offer the flexibility of customized sizes to accommodate your unique requirements.
