DELLOK Aluminum Fin Rolled Exchanger Heat Finned Tube

About us

DELLOK (YONGHUI RADIATING PIPE MANUFACTURING CO.,LTD.) was established in 2002, which is located in Jiangsu, China. After many years of development, the company now has 66 million yuan in fixed assets, more than 200 employees, and 33 technical staffs. We have 4 aluminum processing production lines, with the annual processing capacity of more than 20,000 tons; And we have 5 tube-drawing production lines; 47 fintube production lines, 1 imported production line from American with the brand of McElroy , with the annual production capacity of 12 million meters the above. Quality is the theme of eternal pursuit of winner -Production workshop- Meticulous works, standardized management system and systematic quality assurance are Dellok(YONGHUI)'s best commitment to quality. In Dellok(YONGHUI), the quality control is not only the detection of the final process, but throughout the entire production process. We implement a set of quality control and assurance systems. Each batch of pipes is sampled and tested, and records are kept as a quality guarantee for the final product.

Product Description:

^{Bimetallic Extruded Fin Tube, use base tube insert Aluminium tube,
directly extruded the Aluminium into wanted fin specification. Fin
and tube surface are tight touch thus improving the heat transfer
efficiency. This also give considerable corrosion protection to the
base tube.}

Extruded Aluminum Tube

^{Manufacturing Process:}

^{The Extruded Fin Tubes are produced by compressing an aluminum
tube, or sleeve, onto the base tube. The bloom is exposed to very
high pressures which essentially "grows" the fins into the final
fin profiles.This process manufacture an excellent strong joint
with great resistance (fin stiffness) as well as exceptional heat
transfer capabilities (longevity, temperature range). The advantage
of extruded fin tubes are full protection of bare tube against
corrosion and fin has high mechanical strength. Extruded finned
tubes provide the most stable performance over time as compared to
the other fin types. The fin is rolled from an outer aluminum tube
by a process using pressure to create a rolled "pressure bond"
between the liner tube and fins. The aluminum fin material
completely encloses the tube, except at the ends where a tube
coating can be applied.}

Extruded Aluminum Tubing

^{Extruded Fin Tubes Advantages:}

^{1) Thermal}

^{The bonding of the outer and inner tubes removes the risk of loss
of contact with the aluminium due to thermal stress.}

^{Maximum operating temperature: 250°C. The transfer coeffcient
remains steady. Additionally as the outer sleeve is continuous no
electrolytic couple is created.}

^{2) Mechanical}

^{The fins are more rigid and stand the handling shocks
better,compared to types "G" an "L".}

Extruded Fin Tube

Properties:

Manufacturing Process:- Cold Extrusion

Fin To Tube Bond:- Excellent

Heat Transfer Efficiency:- Excellent

Mechanical Resistance:- Excellent (Hence can be frequently cleaned with high pressure jets unlike other fin tubes. Thereby reducing down time and increasing overall life)

Corrosion Protection:- Gives excellent corrosion protection to the base tube since it entirely covers the base tube (except bare ends).

Temperature Range:- Upto Maximum 300 Deg C

Extruded Fin Tubes

Applications:

^{the petroleum, chemical and petrochemical industries}

^{natural gas treatment}

^{the steel industry: blast furnace and converter cooling systems}

^{power generation: steam turbine exhaust condensing}

^{– contact condensing with cooling of circulating condensate}

^{– fossil and nuclear power plants}

^{air conditioning (freon, ammonia, propane)}

^{incineration of household refuse}

^{compressor coolers, ect.}

^{Product description}

^{Fin Type: Extruded Fin Tube}

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

^{Fin Material: Copper, aluminum}

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 Fibbed 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.}
