The base tubes (pipes) (core tube) of double extruded fin tubes can be stainless steel, carbon steel, corrosion resistant steel, copper and copper alloys, Ti and Ti alloys and the other materials. The base tubes (pipes) (core tube) of single extruded fin tubes can be copper, Nickel-copper, Aluminum and the other materials.

These products are widely used in petroleum, chemical, metallurgy, textile, mechanical and electrical, light industry and pharmaceutical industries in the heating, drying, condensation and cooling equipment.

 

Extruded Finned Tube

 

 

Extruded Finned Tube Manufacturing Process:

 

A carefully degreased core tube is fitted into an aluminium primary tube.This assembly is then fed into the triple-spindle finning head of the fin-extruding 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

Fin materials: Aluminium

Base tube materials: Any metallic material

 

Aluminum Extruded Tubing

 

Extruded Fin Tubes Advantages:

 

Relative thin wall core tubes can be used.

Excellent heat transfer performance (100% contact between tube and fin).

Excellent atmospheric corrosion (complete coverage of the core tube).

Airtight fin to tube bond.

Robust fins resist mechanical damage.

Can be cleaned with high pressure water/steam.

Fin Contact: Interference fit with mechanically solid pressed bond.

Maximum Tube Wall Operating Temperature:300°C.

Type of Service: Medium temperature, severe atmospheric corrosive environment.

 

Extruded Aluminum Tubing

 

Extruded Aluminum Tubing Properties:

 

To improve the heat transfer efficiency in the effective space.

To Reduce the required installation space for the required heat transfer surfaces.

To lower equipment cost while having higher operational reliability.

The running cost is lowered due to lower tube side pressure drop.

The rigidity of tube is increased, which improves the seismic resistance of the tube.

Enhancement of heat transfer, reduction on flow resistance and metal consumption.

 

Extruded Fin Tubes

 

Aluminum Extruded Tubing Applications:

 

High-efficiency fins for higher temperature applications giving complete and permanent atmospheric corrosion protection of the base tube. Using over 40% more aluminium than the equivalent applied fin, the extended fin is very robust and resistant to mechanical damage, allowing the finned tubes to be cleaned without damage using either steam or high-pressure water

Upper limiting temperature: 300°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 manufacturing process

 

Pipe line--compressing or rolling--strip peeling--washing--pressure test--blast blowing--packaging.

The Extruded Fin Tube is formed by a bimetallic tube consisting of an aluminum outer tube and an inner tube of almost any material. The fin is formed by rolling the material from the outside of the outer tube to provide an integrated fin with excellent heat transfer performance and life. The extruded fins provide excellent corrosion protection for the base tube.

The production method of the composite finned tube mainly includes the extrusion method: the bimetallic composite tube is lined with a mandrel, and driven by the rotation of the roller blade, the composite tube is processed on the outer surface through the cavity formed by the rolling groove and the core head Out fins. The heat transfer tube produced by this method is an organic whole with its outer tube and fins, so there is no problem of contact heat loss, and it has good performance and high heat transfer efficiency.

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.
