Silicon Carbide Thermocouple Protection Tube
- [Introduction]: As a temperature measurement sensor, the thermocouple protection tube is usually combined with a temperature transmitter, a regulator and a display instrument to form a process control system, which is used to directly measure or control the temperatures of fluid, steam, gaseous media and solid surfaces in the range of 0-1800℃ in various production processes. Silicon carbide thermocouple protection tube has good heat resistance, oxidation resistance, thermal shock resistance, high temperature wear resistance and other properties, good chemical stability, strong acid and alkali resistance, is an ideal high-performance material.

- Advantages
- We will recommend different materials according to the customer's use environment, such as SiC, NSiC, SSiC, etc.
- We can achieve a wall thickness of 2mm-6mm, which is more convenient for customers to use.
- Short delivery time, usually we have sufficient stock of silicon carbide thermocouple protection tubes and can deliver them at any time. Even if it needs to be customized, the delivery time is about 15 days.
- Product Application
Silicon carbide thermocouple protection tube is widely used in high-temperature measurement and control in metallurgy, chemical industry, ceramics and other industries.
- Our Packing
The two packing methods we use are plywood box packing and solid wood packing, with the solid wood box requires a fumigation certificate. Depending on the various products, we will tailor the proper packaging box; Plastic foam measuring 2 cm to 3 cm thick is placed within the box and secured with row nails. To maintain the products safety during shipment, packing tape is typically used.
