^{Poduct details}

Product Description:

This fin type is formed from a bi-metallic tube consisting of an aluminium outer tube and an inner tube of almost any material. The fin is formed by rolling material from the outside of the exterior tube to give an integral fin with excellent heat transfer properties and longevity. Extruded fin offers excellent corrosion protection of the base tube. Maximum operating temperature for this fin type is 280°C.

Fin material : Aluminium.

Tube materials : No theoretical limits.

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}

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 Fin Tube

Properties:

Cold Extrusion is the manufacturing process.

Excellent Fin-to-Tube Bond

Excellent Heat Transfer Efficiency

Mechanical Resistance: Excellent (as a result, unlike other fin tubes, it can be cleaned often with high-pressure jets). As a result, downtime is reduced and total life is increased.)

Corrosion Protection: Because it completely covers the base tube, it provides excellent corrosion protection (except bare ends).

Temperature Range: Up to 300 degrees Celsius

Extruded Aluminum Tubing

Applications:

Primary extruded finned tubes are used in high temperature conditions and corrosive atmospheric conditions, such as operating temperatures less than 300°C or off-shore applications,heat pipes air to air heat exchangers for HVAC applications,air dehumidification in air treatment plants, energy recovery in air exhaust system. This kind of fin design is the least economical as compared to the other fin types, main reason due to the increased amount of aluminum used around 40% also increased labors during the manufacturing. However this increased cost can be compensated if using lower grade parent tube material.

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 Finned 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.}
