Good Silicon nitride Thermocouple Protection Tube and Sheath is a advanced ceramics, have long working life, more than 12 month

Silicon nitride Thermocouple protection tubes sheaths


Silicon nitride possess a unique combination of physical properties, such as high strength, toughness, excellent thermal shock resistance and resistance to corrosion, which make it the perfect material in this application.




Silicon nitride Thermocouple protection tubes sheaths are state of the art in temperature measuring system for aluminum melt .Melt must be processed, in order to have the desired properties for casting.Therefore it must be kept in the right temperature




Silicon nitride thermocouple protection sheaths tubes are an advanced ceramic tube offering outstanding performance for temperature control in aluminium foundries and smelters and are extremely cost effective compared to other materials, such as cast iron, silicon carbide and alumina.




Characteristics Silicon nitride thermocouple protection sheaths tubes:


non-wetting property


Low coefficient of thermal expansion


Excellent thermal shock resistance


Ability to withstand high structural loads to high temperature




Applications Silicon nitride Thermocouple protection tubes sheaths:


Advanced ceramic thermocouple protection sheaths or tubes for use in the molten aluminium and non-ferrous industry..
