Understanding the Critical Role of Tube Graphite in Industrial Applications
Graphite tubes serve as indispensable components across 83% of high-temperature industrial processes, with the global market projected to reach $2.7 billion by 2028 (Grand View Research, 2023). These cylindrical structures exhibit exceptional thermal conductivity (1700 W/m·K) while maintaining structural integrity at temperatures exceeding 3000°C. A graphite tube factory typically employs isostatic pressing techniques to achieve density levels above 1.85 g/cm³, ensuring optimal performance in extreme environments.
Technical Superiority in Material Engineering
Advanced graphite tube manufacturers utilize modified Acheson furnaces for 240-hour continuous graphitization cycles, achieving 99.97% carbon purity. Key performance metrics include:
- Oxidation resistance up to 535°C in ambient air
- CTE (Coefficient of Thermal Expansion) of 4.5 × 10⁻6/°C
- Ash content below 300 ppm
