High Purity Graphite Tubes Customize Graphite Tube for Industries
1.Resistant to acids
2.Structural strength
3.Impact resistance
4.High volume utilization and high heat transfer effect
5.Long-lasting and easy to maintain
Other Advantages of Graphite Tubes:
When heated from room temperature to 2,000 °C, graphite has the unusual virtue of becoming stronger. The internal tensions in the material affect this characteristic. The internal stresses that occur at room temperature decrease as process temperatures rise, increasing mechanical strength as a result. Increased mechanical robustness enables smaller designs and fewer fixture support systems, which leads to larger batch sizes.
