We have one subsidiary, Function is as follow
|General extrusion production capacity||General specifications of Extruded Fin Tubes|
|Extrusion Facility: 10 finning machines.|
Daily capacity up to 3000 meters.
Extruded fins type: solid plain and serrated.
|Tube OD: 12mm min.~50.8mm(2'') max.|
Tube Length: 18 meters max.
Fin Height: 16.5 mm max.
Fin Thickness: appr. 0.4mm/0.5mm/0.6mm
Fin Pitch: 1.5mm min.
A smooth core tube is inserted into an aluminum sleeve and then the
fins are extruded out of the aluminum sleeve.
The fins are solid plain or serrated into 12,16 or 24 segments or
as your design.
Both plain ends with appr. 10mm~50mm and gaps (Unfinned Section) in the middle.
Both bare ends of Bimetallic Finned Tubes shall be Zinc or Aluminum that metallized applied by an electro spray arc system coating.
Tube Support Box, Clamp or Spacer Box(Materials: Aluminum, Zinc or
The common application fileds are:
- Heat exchangers units for power plant(electric, nuclear, thermal
and geothermal power plants);
- High corrosive systems (condensers, evaporators, sea water
desalinations, fertilizing, urea systems, ammonia, gas, corrosive
- The petroleum, chemical and petrochemical industries;
- The food processing and refrigeration industries;
- Natural gas treatment;
Extruded Bimetallic Finned Tube is combined with two different

- We have more than 10,000 square meters workshop, including 10
extrusion finning machines, daily extrusion capacity up to 3,000
- 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...
- DR-extruded bimetallic fin tubes maximum operating temperature: 300
degree. The transfer coefficient remains steady.
- DR-extruded bimetallic fin tubes have stronger fins than other
mechanical fins, like L, LL, KL, and G, so it is much easier to
- 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.
