Boiler Fin Tube High Strength Integrated Extruded Spiral Type
1.Finned Tube Heat Exchangers consist of a shell and finned tubes
2.Fins are used to increase the effective surface area of heat
3.Finned tubes are used when the heat transfer coefficient on the
outside of the tubes is appreciably lower than that on the
inside;as in heat transfer from a liquid to a gas,vapor to a gas
,such as steam to air heat exchanger, thermic fluid to air heat
exchanger, when an extended surface is needed on only one fluid
side or when the operating pressure needs to be contained on one
|Medium||air, flue gas, thermal oil, water, brine, refrigerant, etc.|
|Temperature||standard heat exchanger to 560 ° C by special materials can be
|Pipe materials||carbon steel, stainless steel, alloy or special materials|
|Ribs materials||carbon steel, stainless steel, non-ferrous metal, alloy or special
|Thermal insulation &Surface treatment||according to customers specification|
1. The equipment body can be designed into many modules to ensure
the long term and stable running.
2. Compact structure which can enlarge the heat exchanging area in
order to add the heat transfer area and less leakage.
3. Improve the heat transfer efficiency.
4. Structure arrangement: In line or staggered arrangement.
|Spiral Wrapped Fin|
|Each tube is individually finned||Increased thermal conductivity|
|Less fin material used|
|Ability to replace a single damaged tube|
|More compact fin bundle|
|Tube face and row centers can vary|
|Allows coil to better fit with existing case height|
|Pitch to drain a multi-row for vertical airflow|
|Tension Bond||Use various fin and tube materials|
|Use various fin and tube thicknesses|
|Embedded Fin||Maintain fin bond at high temperatures|
|Header||Accommodates header thermal expansion|
|Allows longer header stubs|
1.Our products can be modified according to our customers' needs
and the situation.
2.we design and manufacture safe,reliable and efficient H-fin
tubes.HD BOILER has also completed stand-alone product quality
3.Production of H-fin tubes are with high heat transfer efficiency,
they have flue gas resistance and are designed for a small space.
