Application
In some special occasions, such as chemical plants, smelters, thermal power plants and so on, special material and structure thermal resistance and thermocouple are required.
There are three kinds of wear resistant coatings. The material hardness is HRC58-62, temperature range is 0-600centigrade, 0-800centigrade(A), 0-1000centigrade(B). Corrosion-resistant coatings have good anti-corrosion performance. In addition to melt molten lithium, potassium, sodium, hydrofluoric acid, chlorine trifluoride, it almost can resist all of chemical media. It has long service life within 0_250 centigrade. If the fixed thread is made into corrosion_resistant structure, then the thread can not work under pressure environment.
