product advantages

Ultra-high temperature resistance 
It can operate stably for a long time in a high-temperature environment of 1800℃, far exceeding the temperature limit of metal heating elements, and is not prone to deformation or softening under high temperatures.

Excellent thermal conductivity 
Graphite features high thermal conductivity, enabling rapid heating-up and uniform temperature distribution. It can effectively reduce equipment energy consumption and shorten the process cycle.

Corrosion resistance & chemical stability 
It has good resistance to corrosive media such as acids, alkalis and salts, as well as most gases (e.g., inert gases, reducing gases), and is not susceptible to oxidation or chemical reactions.

Low thermal expansion coefficient 
The volume change is minimal during high-temperature heating and low-temperature cooling processes, which can prevent cracking or damage caused by thermal expansion and contraction, and extend the service life.

product applications

High-temperature furnace gas circulation system 
It serves as the delivery pipeline for inert gases (argon, nitrogen) in vacuum furnaces and nitriding furnaces, achieving precise control of the furnace atmosphere.

Chemical and semiconductor industries 
It is applicable for the delivery of high-purity corrosive gases (e.g., hydrogen chloride, fluorine gas) and the gas guiding in the manufacturing process of semiconductor wafers.

Metallurgical waste gas treatment 
It acts as the high-temperature waste gas discharge pipeline for smelting furnaces and refining furnaces, withstanding the high temperature and corrosive components in the waste gas.

Photovoltaic and carbon fiber production 
It is used as the inert gas protection pipeline for carbon fiber carbonization furnaces, ensuring that carbon fibers are not oxidized during the high-temperature carbonization process.
