Extruded finned tube Advantage:
1. Optimized inner to outer surface ratio
2. High heat exchange rate
3. Enhanced structure due to the roll forming process
4. Flexible as straight tube or bent or coiled heat exchangers
5. Low heat resistance between fins and tube
6. Strong resistance to shock and thermal expansion and contraction
7. Cost and energy saving due to long service life and high exchange rate

 

 


Extruded Fin Tube, also known as Bimetallic Fin Tube, is a popular finning method for a variety of applications. The fins are created by extruding them onto an aluminium muff tube that is built to fit over the base tube with a tight tolerance.
Extrusion is performed using a Continuous Fin Extruder with Three Tooling Rolls, and high pressures in the range of 1200 psi are used. The cold working procedure ensures a perfect bond between the tube and the fin, resulting in great heat transfer efficiency. Simultaneously, the mechanical strength of the fins is greatly improved.
Fin Tubes are used in AIR FIN COOLERS, DRIERS, RADIATORS, and other applications in industries such as food and agriculture, power plants, chemical industries, steel plants, and chiller plants, among others.

 

 


 

Extruded finned tube features:

 

 

The finned tube provide by us is Extruded Type, which is different from the ones through HF Welding and Wrapping method. The fins are obtained by roll forming the outer surface of a soft seamless plain tube. The technology simply squeezes the wall thickness transforming into straight fins on the tube. So the fin and the tube are integrated and inseparable, which avoids the heat resistance between fin and tube, and optimizes heat exchange efficiency. Based on this structure, the Extruded type can survive more severe working conditions than other finned tubes. Also it, on the other hand, shows several unique features such as enhanced physical structure, resistance to vibration, anti-corrosion ability, and long service life, etc.

 

Extruded Finned Tube

 

Under this technology, there are two major types of finned tubes available with us, Single metal tubes and Bimetallic tubes. The former uses Copper, Aluminum, and Copper Nickel alone. The later has a core tube on the inside made of harder material. In this case, the outer tube is rolled onto the core tube in order to provide for a tight bond and good thermal contact between the two tubes.

 

Extruded Aluminum Tubing

 

Customized finned tube is available. The specification table is followed below. If required, the fin tube can be made into various forms after soft annealing process. They can be used for cooling and heating in a large scale of conditions. For example, coils in water heater, oil cooler in large machines, heat transfer part in boiler and heat recovering system, air-conditioning and refrigeration industry as condenser part or evaporator part, etc.

 

Aluminum Extruded Tubing

 

The material for our fin tube covers Copper(C10200, C12000, C12200), Copper Nickel(C70600), Aluminum(1060), Aluminum alloy, Aluminum-Steel(bimetallic), Aluminum-Stainless Steel(bimetallic), Aluminum-Copper(bimetallic), Aluminum-Copper Nickel(bimetallic), Copper-Copper Nickel(bimetallic).

FAQ

 

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.

 

5. Where are extruded fin tubes used?

Extruded Fin Tubes are widely used in the refinery, petrochemical and chemical industry for:

Air-cooled condensers

Air-cooled coolers for products

Gas coolers

Gas heaters

 

6. How do you ensure a quality product?

We adhere to an in-house Quality System (or QMS) based on Industry Standards such as ASME, the National Board of Boilers & Pressure Vessels, and customer requirements. Our quality system is documented, audited, and enforced by our Quality Control department.
