A core tube is fitted into an aluminium primary tube. This assembly is then fed into the triple-spindle finning machine. Three special multi-disc packs extrude the aluminium tube into helical high fins while reducing the inner diameter to give firm pressure contact with the core tube. 

Finned tube Application: 
*cooling unit:air cooler,water cooler,oil cooler 
*Product coolers - gas, chemicals, petrochemicals, oil etc. 
*Heat exchangers 

*Application aerospace:boiler,dry,heat exchange,boiler economizer, power plant waste heat boiler, petrochemical engineering

High-efficiency fins for higher temperature applications giving complete and permanent atmospheric corrosion protection of the base tube.

G-Fin Tube is an aluminium  fin stripped tube, which is wounded into a machined groove and securely locked 

into place by back filling with base tube material. This ensures that maximum heat transfer is maintained at high

 tube metal temperatures.


  *Maximum working temperature: 400 deg C. 

  *Atmospheric corrosion resistance: Poor
  *Mechanical resistance: Acceptable
  *Fin materials: Aluminium, Copper, Carbon steel


Embedded Fin Tube  ("G") Type 



Fins Are Uniform, High Precision.



Application: Air Cooler


The aluminium strip is embedded under the tension in a groove of the base tube. The G type fin tube is applicable to high temperature.

Temp. 400°c
