^{Extruded Fin Tube Product Description:}

^{Copper-aluminum composite finned tube is a copper-aluminum
composite tube that is rolled out of fins after compounding. It has
the characteristics of close combination, small thermal resistance,
good heat transfer performance, high strength, small flow loss and
strong corrosion resistance. It is not easy to be deformed in the
case of long-term cold and hot work and long working life.}

^{The whole rolled fin is smooth without burr, no wrinkle, easy to
clean, in the heating and air conditioning engineering wet cooling
is easy to remove the condensation on the outside surface of the
fin, in the heat exchange heating and other occasions not easy to
dust, fouling.}

^{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. Longitudinal slots are cut into the
outer periphery with inclined fin tips.}

^{Fin Material: Aluminium.}

^{Core Tube Material: Carbon Steel/ Carbon}

^{Alloy Steel/Stainless Steel/ Nickel Alloys/Copper/Copper
Alloys/Titanium.}

^{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 Properties:}

^{The extruded fin is formed from an outer aluminum tube with a large
wall thickness (muff), which is aligned over an inner base tube.
The two tubes are pushed through three arbors with rotating discs
that literally squeeze or extrude the aluminum fins up and out of
the muff material in a spiral shape in one operation. The resultant
fin typically has a base or root thickness of .035", average fin
thickness .016" and a tip of .009", with an overall height of 16mm
(5/8"). The root thickness serves to form an uninterrupted bond
over the entire tube length.}

^{Murphy disc technology now makes it possible to fin thinner muff
thus offering significant material savings. Recommended standard
muff wall is .176" as opposed to industry practice of .183"-.210"
In addition, the same growth factor can be used for pitches from 8
- 11 FPI, allowing for standardization on one muff thickness and
eliminating the need to stock multiple muff wall thicknesses. The
same discs can be used to produce 5/8" (15,9mm) or 1/2" (12,7 mm)
high fin.}

^{Model B produces a 5/8" high fin on tube sizes from 25mm to 1.5" (
38.1mm). The Model B Extruded Finning Machine is now capable of
7/16" high integral copper fin at 7 to 10 FPI within the tube size
range of the machine (25mm and 1.5"). Each machine is configured
for the specific production requirements of the end user.}

^{Product description}

^{Fin Type: Extruded Fin Tube}

^{Tube Material: copper, copper nickel, stainless steel, titanium
etc.}

^{Fin Material: Copper, aluminum}

^{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.}
