Artificial Anti Oxidation Degassing Extruded Graphite Pipe
Programmable properties:
1. high thermal and chemical resistance
2. good thermal conductivity
3. low coefficient of thermal expansion
4. minimal wettability to molten metals
Applications:
1. as refractory materials: graphite and its products with high temperature, high strength properties, in the metallurgical industry it is widely used to make graphite crucibles, in steelmaking use graphite as the ingot protectant, metallurgical furnace lining.
2.as conductive material: in the electric industry used to make electrode, the brush, the carbon rods, carbon nanotubes, the positive of the mercury flow, graphite gaskets, phone parts, the television screen coating etc.
3. As wear-resisting lubrication materials: graphite in mechanical industry commonly as a lubricant.
4. Graphite has good chemical stability. is used to make a large heat exchanger, the reaction tank, condensed device, burning tower, absorption tower, cooler, heater, filters, pump equipment. Widely used in petroleum chemical industry, wet metallurgy, acid and alkali production, synthetic fiber, paper and other industrial department, can save a lot of metal materials.
5. Make casting, FanSha, molding and high temperature metallurgical materials
6.Used for atomic energy industry and national defense industry
