Mono-metal fin tube is made by a soft metal tube through in thread rolling process. This kind of tube is one piece extruded finned tubes, without any inner tubes). Usually the material is pure aluminum Al1060 or pure copper C12200 or Nickel CuproBFe10-1-1.
According to finished fin height, it can be divided into integral low fin tube and mono metal high fin tube.
Mono metal fin tube is also called single metal fin tube. Fin dimension range is as below.
Tube OD: 12~30mm
Tube Inside Diameter: 7~20mm
Fin Pitch: 1.6~5mm
Fin Thickness: 0.2~0.5mm
Finned height: 1.5~6mm
Bottom Wall Thickness: ＞0.75mm
Manufacturing Process: Cold Extrusion
Fin to tube Bond: Excellent
Heat Transfer Efficiency: Excellent
Mechanical Resistance: Excellent (Hence can be frequently cleaned with high pressure jets unlike other fin tubes. Thereby reducing down time and increasing overall life)
Corrosion Protection: Gives excellent corrosion protection to the base tube since it entirely covers the base tube (except bare ends)
While double metal composited fin tube is with dimensions below:
Diameter range of base tube of 3/4’’ up to 2’’, fin number per inch: 6~14FPI.
Base Tube Material: all materials are available.
Fin Material: Aluminum, Copper
