Our graphite pipe, made from good performance graphite blocks, are widely used in metallurgy, machinery, electronics and chemical industry, etc. We could supply fine-grain graphite, medium-grain graphite, high pure graphite, isostatic graphite, kinds of domestic and imported graphite, and so on.
The characteristics of our graphite pipe:
1. low electric resistance
2. high temperature resistance
3. good electric and thermal conductivity
4. high oxidation resistance
5. greater resistance to thermal and mechanical shock
6. high mechanical strength and machining accuracy
7. homogeneous structure
8. hard surface and good flexural strength
