Implication of Finned Tube

In order to improve the efficiency of heat transfer, fins are usually added on the surface of heat exchanger tubes to increase the outer surface area (or inner surface area) of heat exchanger tubes, so as to achieve the purpose of improving the efficiency of heat transfer. Such heat exchanger tubes are called finned tubes.

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
• 9.Anti-corrosion
• 10.Anti-wear
• 11.Low contact resistance
• 12.High stability
• 13.Anti-ash ability

Take Tube Number M-11045.180100.00 as example

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

Applications:

1. 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).

2. Finned tubes, as heat exchange elements, have been working under high temperature flue gas for a long time. For example, finned tubes used in boiler heat exchangers are in a bad environment, high temperature and pressure, and in a corrosive atmosphere, which requires finned tubes to have high performance indicators.
