Thermocouples have become the most widely used temperature sensing elements in industrial production and scientific research. The performance of thermocouple protection tube material affects various performance indicators such as long-term stability and service life of thermocouples. Especially thermocouples working in high temperature environment have higher requirements on materials. For example, continuous temperature measurement of molten steel, thermocouple protection sleeve not only has to withstand high temperature, but also is corroded and impacted by hot molten steel. When the temperature is measured in a circulating fluidized bed boiler, there are not only high temperature oxidation and high temperature corrosion, but also high temperature erosion wear of fluid powder. Such a harsh working environment is a severe test for the protective casing material, and it also poses a difficult problem for engineers and technicians – how to solve the failure problem of thermocouple protective casing in a high temperature environment economically and practically? 

SYTOP has a well-formulated molten steel temperature measurement protection tube, which is widely used in the field of continuous temperature measurement of high-temperature alloy molten steel with excellent service life.
