Summary:

In some special occasions, such as chemical plants, smelters, thermal power plants, the use of special materials and structure of the thermocouple.

Corrosion resistant coating has good corrosion resistance, in addition to molten lithium metal, potassium, sodium, hydrofluoric acid, oxygen trifluoride high flow rate of liquid fluorine, it is almost resistant to all of its chemical media, in the range of 0-250℃ long-term use. If the fixed thread is to be of rot resistant construction, the thread shall not work under pressure.

Titanium alloy tube resistant to seawater, all kinds of chloride and hypochlorite, wet chlorine and oxidizing acid (including smoking nitric acid) alkali corrosion, not resistant to more pure reducing acid (sulfuric acid, hydrochloric acid) corrosion, titanium alloy tube temperature range below 500℃, this product is still in line with JB/T9238-1999 and JB/T8622-1997.
