Process Flow:
1. Order raw material due to customers' requirements.
2. Inspection on raw material at arrival
3. Roll forming the fin tube, while monitoring the whole process / Extruding or finning process
4. Cut into required length
5. Inspection on specification of finned tube
6. If required, we provide de-fin process, soft annealing, bending and coiling, welding connectors
7. Clean procedure, pressure test and drying
8. Packing for delivery
Advantages:
1. Optimized heat exchange performance of raw material with extruding process
2. Compact design consuming less assembling space
3. Flexible for customized design after soft annealing
4. Copper is a hygienic and antimicrobial material for use in drink water systems
5. Tin plating for both inside and outside surface is possible, if requested
6. Easier to stock after surface treatment
7. Resistance to both vibration and corrosion
8. Cost saving from longer service life and less assembling space
Applications:
The finned tube coils or heat exchangers are mainly used in heating(gas-fired boilers, condensing boilers, flue gas condensers), in heating of drink waters and as tankless water heaters, 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).
