WRE/WRE2-330-F corrosion-resistant thermocouple(movable flange)
WREN/WREN2-330 wear-resistant thermocouple （movable flange）
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.
