Description

Extruded Finned Tube normally is consist of two kinds of metallic tube. The outer tube is normally aluminium tube while the inner tube are often copper or steel tube. The outer fins are processed by cold rotary extrusion machine as follow of picture. Initially the outer tube’s diameter is bigger than inner tube diameter, then the outer tube is pushed through three arbors with rotating discs which extrude the aluminium fins up and out of the aluminium tube in a spiral shape. Then the outer aluminum tube diameter reduces and fit to the inner tube closely, forming a tight mechanical bond between the inner and outer tubes, making the gap disapper and ensuring good heat transfer efficiency .  

Specification:

Fins material: Aluminum 1060 Fins number: 6-11 fins per inch Fin Height: 5-20mm Fin Thickness:0.4-5mm Base Tube Material:Carbon Steel, Stainless Steel, Alloy Steel, Copper,Nickel, Titanium and other material. Base Tube OD:10-323.85mm Base Tube Thickness: 2.31-9.53mm Base Tube Length: Within 25 meters  

Advantage:

  1. The fin and tube are fit closely, can provide high heat transfer efficiency;
  2. The Aluminium fins cover the base tube wholely, can protect the base tube;
  3. Adapt to rough service, high temperatures and corrosive environment.
  4. Extruded finned tube is with simple process and cheap material but with high heat transfer efficiency, making this type finned tube high performance cost ratio.
  5. Easy to clean with a high-pressure water jet without deforming the fins.

Application:

Upper temperature limit: Extruded Finned tubes are commonly used in applications with temperature up to 325℃ Air-cooled condensers Air-cooled coolers for products Gas coolers Gas heaters  

Package:

Wooden Package with steel frame

 

Jinbes has eight production lines for the extruded fined tube. We also have three sets of cutting machines to cut the finned tubes into different length according to customers’ requirements. If you have any futher design requirements, welcome to send us your technical drawings, we can provide our solution for your reference and will try our best to support you.
