SiC heat exchanger tube
Detailed
High thermal conductivity:
The thermal conductivity of SiC is 140 W/mK, twice that of modified graphite, 2.5 times that of tantalum, 5 times that of stainless steel, 15 times that of enamel and 20 times that of Teflon.
• Less heat transfer area
• Smaller heat exchanger size
• Smaller heat exchanger size
High corrosion resistance：
| Corrosive Medium | Temperature ˚C | Corrosion Rate (mg/cm2 years) |
| 98% H₂SO₄ | 100 | 1.8 |
| 85% H3SO₄ | 100 | <0.2 |
| 54% HF | 25 | <0.2 |
| 50% NaOH | 100 | 2.5 |
| 45% KOH | 100 | <0.2 |
| 70% HNO3 | 100 | <0.2 |
| 37% HCl | 86 | <0.2 |
| 10% HF 和 HNO3 | 25 | <0.2 |
• The only ceramic material resistant to hydrofluoric acid corrosion
• Resistant to high concentration of nitric acid, sulfuric acid, mixed acid, alkali, oxidant and organic chloric acid.
