Aluminium fin tubes
Can quote for aluminium fin tubes for air cooled heat exchangers in various materials like carbon steel, stainless steel, and non ferrous materails
The strip material is subjected to controlled deformation under tension giving the optimum contact pressure of the foot of the fin onto the base tube thus maximising the heat transfer properties. The foot of the fin considerably enhances the corrosion protection of the base tube.
Maximum Working Temperature: 150â??
Atmospheric Corrosion Resistance: Acceptable
Mechnical Resistance: Poor
Fin Materials: Aluminum, Copper
Tube Materials: No theoretical limits.
'LL' Finned Tube
å?¾ç??3.png
Manufactured in the same way as the 'L' fin type except that the fin foot is overlapped to completely enclose the base tube thereby giving excellent corrosion resistance. This type of tube is often used as an alternative to the more expensive extruded type fin in corrosive environments.
Maximum Working Temperature: 180â??
Atmospheric Corrosion Resistance: Acceptable
Mechnical Resistance: Poor
Fin Materials: Aluminum, Copper
Tube Materials: No theoretical limits.
'KL' Finned Tube
å?¾ç??3.png
Manufactured exactly as the 'L' fin except that the base tube is knurled before application of the fin foot. After application the fin foot is knurled into the corresponding knurling on the base tube thereby enhancing the bond between the fin and tube resulting in improved heat transfer characteristics.
Maximum Working Temperature: 260â??
Atmospheric Corrosion Resistance: Acceptable
Mechnical Resistance: Acceptable
Fin Materials: Aluminum, Copper
Tube Materials: No theoretical limits.
'G' Embedded Finned Tube
å?¾ç??3.png
(Embedded Fin)The fin strip is wound 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: 450â??
Atmospheric Corrosion Resistance: Poor
Mechnical Resistance: Acceptable
Fin Materials: Aluminum, Copper, Carbon Steel
Tube Materials: No theoretical limits.

Process: the extruded fin tube is bimetallic combined with integral aluminum fins on the outside surface. The base tube is inserted inside the aluminum tube and both tubes are passed through extrusion machine. The tight mechanical bond between aluminum tube and inner base tube is accomplished during the fining work and same time makes the n steel, low-alloy steels, stainless steel , brass , copper , cooper-nickel alloys , aluminum bronze , nickel alloys , titanium etc...

High-efficiency fins for higher temperature applications giving complete and permanent atmospheric corrosion protection of the base tube.
ACC tube has an outer layer of antirust 3003 aluminum alloy and inner layer of oxygen-free copper. The copper-aluminum interface achieves metals bonging among atoms, popular saying: metallurgy bonding. ACC tube combines the excellent moment decalescence capability of copper with the excellent heat-sinking capability of aluminum. Thus, ACC tube owns good heat-transmit performance, which can be widely applied in air conditioner, refrigeration, dehumidifier and so on.
The heat exchanger, adopting ACC tube, completely eradicates the electrochemistry decays between copper tube and aluminum of traditional heat-exchanger. Greatly reduces the recession of energy efficiency ratio, provides key material for making long-effect air conditioner, and saves more than30% purchase cost for manufacturer.
Over millions of air-conditioners have been put to market. Anti-corrosion and heat exchange performance can meet the requirements.
NOTE : All index and parameters achieve related standards after testing the air-conditioner made by ACC tube, which has run for over 5 years.

Alloy designations
The aluminium industry has created a system using a fourdigit numerical designation to identify wrought aluminium alloys The first digit indicates the major alloying element The second digit indicates whether there was a modification in the basic alloy The third and fourth digit indicates the specific alloy

Manufacture:
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.
Application:
*Air water cooler unit
*Product coolers - gas, chemicals, petrochemicals, oil etc.
*Heat exchangers
*Boiler,Dryer
*Air condtioner, Air condenser
