Product Description:


Made of standard grade aluminum or copper, the provided Extruded Aluminum Fin Tubes are widely used as indispensable components for heater or heat exchanging equipments. The smooth design of the fin part of these tubes has simplified their cleaning process. The anodized surface finishing of their fins act as the perfect barrier against corrosion. These fin tubes are completely protected against thermal shock, have necessary heat transferring surface, can endure mechanical shock and deliver outstanding thermal performance. Featured with anti corrosion design, these Extruded Aluminum Fin Tubes can withstand high temperature, corrosion prone working environment and extreme pressure. These remain functional for longer period.



Extruded Finned Tube


Extruded Finned Tube Manufacturing Process:

The fins are rotary cold rolled from a smooth thick walled hollow blank tube slid over the core tube. Three multi spindle disc packs extrude the hollow blank tube into helical high fins.

During this process the inner diameter of the hollow blank tube is reduced and at the same time pressed on the core tube. This results in a mechanically solid joint.

Fin Material: Aluminium/Copper.

Core Tube Material: Carbon Steel/ Carbon/Alloy Steel/Stainless Steel/ Nickel Alloys/Copper/Copper Alloys/Titanium


Extruded Fin Tubes


Extruded Fin Tubes Advantages:


100% fin-to-tube bond providing exceptional efficiency and longevity.

Excellent corrosion protection on the base tube.

Easy to clean with a high-pressure water jet without deforming the fins.

As the outer sleeve is continuous No galvanic corrosion between the tube and fins.

The bonding of the outer and inner tubes removes the risk of loss of contact with the aluminium due to thermal stress and fins are vibration resistant.

Higher heat transfer performance for the life of the unit.

Extruded Finned tubes are commonly used in applications with temperature up to 325 °c.

Extruded Aluminum Tubing


Aluminum extruded finned tubes using the form of the base tube covered with aluminum tube(the base tube can be carbon steel, stainless steel, copper) through machine extrusion, forming a tube fin, the fin base and the tube outer wall is close fitting, this fin tubing control can make finned tubes with high heat transfer coefficient and heat transfer performance.


Aluminum extruded finned tubes, also called [integral finned tubes" using the form of the base tube covered with aluminum tube(the base tube can be carbon steel, stainless steel, copper) through machine extrusion, forming a tube fin, the fin base and the tube outer wall is close fitting, this fin tubing control can make finned tubes with high heat transfer coefficient and heat transfer performance. Extruded Finned Tube can be made of iron, copper or aluminum tube by compound rolling, which has the advantages of tight bonding, small thermal resistance, good heat transfer performance, high strength, small flow loss, strong anti-corrosion performance, not easy to deformation under long-term hot and cold working conditions, long working life and so on.


Extruded Finned Tube







1. What Does Fin Tube Mean?

A fin tube is a tube that has small fins around the outside surface. These fins act as a filter and a mechanism to transfer heat from the material inside the tube to the outside space or vice versa. Fin tubes are used in applications that require a transfer of heat from a hot fluid to a colder fluid through the tube's wall. The rate at which such heat transfer occurs depends on three factors:

The temperature difference between the two fluids.

The heat transfer coefficient between each of the fluids and the tube wall.

The surface area to which the fluid is exposed.


2. Where is finned tube heat exchanger used?

Finned tube heat exchangers generally use air to cool or heat fluids such as air, water, oil or gas, or they can be used to capture or recover waste heat. These heat exchangers can used in a broad range of industries including oil & gas, power generation, marine and HVAC&R.


3. What is extruded fin tube?

Extruded finned tubes are bimetallic tubes whose outer aluminium surface is finned by cold plastic deformation. There are two major types of finned tubes available with us, single metal tubes (also called mono metallic fin tube) and Bimetallic tube (composite extruded fin tube) .


4. Why Aluminium is recommended as a fin material?

Good corrosion resistance, formability and high thermal conductivity make aluminium an ideal material for the construction of these heat exchangers. A typical brazed heat exchanger (radiator or condenser) comprises fins, tubes, sideplates and headerplates.
