Tube Number Code System
Take Tube Number M-11045.180100.00 as example
| M | 11 | 045 | 180 | 100 | 00 |
| M=Medium Height H=High L=Low | Minimum fins per Inch | Fin Height in 1/10 mm | Minimum Root Diameter in 1/10 mm | Root Wall-thickness in 1/100 mm | Code of Inner Surface 00=plain 01=Undulated 02=Grooved |
Descriptions:
Specifications:
| Customized Outside diameter and Inside Diameter | |
| Fin Height | 0~12mm |
| Fins per Inch | 5~26 |
| Fin Thickness | 0.3~0.5mm |
| Wall thickness | 0.7~2mm |
Advantage:
1. Optimized inner to outer surface ratio
2. High heat exchange rate
3. Enhanced structure due to the roll forming process
4. Flexible as straight tube or bent or coiled heat exchangers
5. Low heat resistance between fins and tube
6. Strong resistance to shock and thermal expansion and contraction
7. Cost and energy saving due to long service life and high exchange rate
Applications:
The fin tubes are mainly used in heating(gas-fired boilers, condensing boilers, flue gas condensers), in mechanical and automotive engineering(oil coolers, mine coolers, air coolers for diesel engines), in chemical engineering(gas coolers and heater, process cooler), in power plants(air cooler, cooling tower), and in nuclear engineering(uranium enrichment plants).
