Product Description

High Insulation 2 or 4 Hole 99.7% Alumina Thermocouple Ceramic Insulator


Gongtao company mainly produce alumina tubes, rods and various industrial ceramic parts, which are mainly used in thermalcouple temperature, liquid steel continous temperature, various industrial furnace(containig vacuum furnace, carburizing furnace, wire furnace, atmosphere furnace etc), especially widely used in petrochemical, spinning, electric, instrumentation, mechanical workout, military project etc industry.
Sillimatin 60 Type C 530, Alsint 99.7 Type C 799 and Pythagoras Type C 610, all complying with DIN VDE 0335.
The main applications are in the area of thermal processes. Protection tubes, insulators, radiant tubes, support tubes for electric heaters, beams, profiles, incineration aids and special fabrications.
The Impervious Materials are:
Alsint(Re-crystallised Alumina) is rated to 1700oC
Pythagoras(Aluminous Porcelain) is rated to 1400oC
The Porous Material is:
Sillimantin 60 and is rated at 1350oC
Sillimantin has better thermal shock resistance and is used mainly in furnace tubes, however can be used as an outer protection sheath if thermal shock is critical.
Noble metal thermocouple protection, furnace tubes, high temperature vacuum furnaces, heat treating furnace rollers, radiant tubes, laser tubes, corona treater tubes and ozone generators.
Corrosive environments and electrical insulation applications. Noble metal thermocouples and diffusion furnace profile couples, laser wave guides and RTD's
