Provide customers a comprehensive purchasing platform of industrial and electric heat ceramic products

Description
Alumina (Al2O3) has a wide application due to its versatility and low material cost. Alumina possesses a high melting point, strong hardness, and good chemical stability, making it a good material to withstand high temperature and chemical corrosion. Our alumina furnace tubes, alumina thermocouple protection tubes and insulators, and alumina rods are available in a variety of diameters and lengths. Call for any custom production request.

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.
 
Our items are various and exported to many countries.Welcome to contact us!
