Serrated Extruded Heat Exchanger aluminum Fin Tube , A179 seamless Carbon Steel tubes

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. 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...
2. DR-extruded bimetallic fin tubes maximum operating temperature: 300 degree. The transfer coefficient remains steady.
3. 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.
4. 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.
