L type Extruded Fin Tube Cooling Aluminum Finned Tube Copper Fin Pipes for Air Cooler

1) Tube OD:25mm~82.5mm
2) Length: 130mm~18m
3) fin height : 0mm-16mm
4) Fin pitch:2.0-5.0mm
5) finned tube length:0.5m~ 14m
6) Single metal rolling finned tube: Pure aluminum 1060 /aluminum alloy 6063 the 6061 material
7) Double metal rolling finned tube: Tube-based protection from the outer layer of aluminum tubes, corrosion-resistant;
8) Base tube material: carbon steel pipe/stainless steel tube/ copper tube / titanium alloy tube
9) Package: The aluminum finned tubes are well packed in plastic film in the inner and steel frame in the outer

Description:
Manufacturing Process
A smooth core tube is inserted into an aluminum sleeve and then the fins are extruded out of the aluminum sleeve.

Fins Type:
The fins are solid plain or serrated into 12,16 or 24 segments or as your design.

Unfinned Section
Both plain ends with appr. 10mm~50mm and gaps (Unfinned Section) in the middle.

Surface Coating
Both bare ends of Bimetallic Finned Tubes shall be Zinc or Aluminum that metallized applied by an electro spray arc system coating.

Accessories
Tube Support Box, Clamp or Spacer Box(Materials: Aluminum, Zinc or Stainless Steel).

Applications:

The common application fileds are:

1. Heat exchangers units for power plant(electric, nuclear, thermal and geothermal power plants);
2. High corrosive systems (condensers, evaporators, sea water desalinations, fertilizing, urea systems, ammonia, gas, corrosive acids);
3. The petroleum, chemical and petrochemical industries;
4. The food processing and refrigeration industries;
5. Natural gas treatment;

Specifications:

Extruded Bimetallic Finned Tube is combined with two different materials.

Competitive Advantage:

1. We have more than 10,000 square meters workshop, including 10 extrusion finning machines, daily extrusion capacity up to 3,000 Meters.
2. The extrusion finning machines are designed and assembled by ourselves and we can offer you finning machines, extrusion muff sleeves and all accessories (extrusion finning disks) etc...
3. DR-extruded bimetallic fin tubes maximum operating temperature: 300 degree. The transfer coefficient remains steady.
4. DR-extruded bimetallic fin tubes have stronger fins than other mechanical fins, like L, LL, KL, and G, so it is much easier to clean.
5. In application of high stress and corrosive condiction, DR-extruded bimetallic fin tubes provides an excellent technical and economical savings in comparsion to a costlier single alloy tube, as the use of costlier material is reduced to the min.
