Graphite Pipes


Graphite pipe are made of fine grain graphite materials and are available in various sizes. It is most frequently used for Aluminum degassing in the metal manufacturing industry, and the highest temperature of the graphite pipe can reach 3000℃. It’s also widely used in a heat source or heat radiation of high-temperature environments and other various mechanical friction conditions.
