Graphite electrode used for quartz heating pipe

The invention discloses a graphite electrode used for a quartz heating pipe, which comprises a graphite electrode 1, a graphite electrode 2 and a metal wire 3 and is characterized in that the graphite electrode 1 is connected with a heating wire in the quartz heating pipe, the graphite electrode 1 is connected with the graphite electrode 2 provided with threads, and the metal wire 3 arranged on the graphite electrode 2 is connected with a power supply. The graphite electrode used for the quartz heating pipe has good effect for preventing the quartz heating pipe from cracking caused by excessive large heating amount, and is wide in raw materials and low in price, thereby being capable of being widely used serving as the electrode of the quartz heating pipe.
