Description:
Manufacturing Process
A smooth core tube is inserted into an aluminum sleeve and then the
fins are extruded out of the aluminum sleeve.
Fin Types
The fins are solid plain or serrated into 12,16 or 24 segments.
Un-finned Sections
We provide extruded fin tubes with Unfinned Section gaps in the
middle.
Protection of Ends
Both bare ends of Extruded 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).
Delivery Condition
Tube ends are square cut, free burrs, internally dried and air
blown clean, externally coated with varnish at both ends of DR Type
Tubes.
The desiccants are put into each package for continental
transportation as well.
Applications:
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
acids);
- The petroleum, chemical and petrochemical industries;
- The food processing and refrigeration industries;
- Natural gas treatment;

Competitive Advantage:
- We have more than 10,000 square meters workshop, including 10
extrusion finning machines, daily extrusion capacity up to 3,000
Meters.
- 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
clean.
- 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.
