2. General Review on Different Fin Tubes’ Specifications

3. Extruded Fin Tube
Aluminum rolling finned tube is rolling as a whole by the aluminum tube, which has the
feather of no contact thermal resistance, high strength, thermal shock and mechanical
shock, good thermal performance, and considerable expansion heat transfer surface. It
can be bi-metal or mono metallic tubes.
Bare tube material:
Carbon steel tube: SA179, SA334, SA214, SA106B, GB8163, GB9948, GB3087,10#, 20#,
Stainless steel tube: SA789, SA213, SA312, SA210, SA249, 304, 316, T11, T22, T91
Copper tube: C1100, C12200, C44300, C68700, C70600, C71500, CuNi90/10,
70/10,70/20,70/30
Fin material: Aluminium 1060,1050, 1070, 6063,6061,3003

4. Low Fin Tube
The process of integral low finned tube is similar to extruded finned tube, the difference
is the fin of low fin tube is made from the same tube obtaining a fin of lower height.
After rolling process, the outer surface of tube is formed with thread, which makes the
finned tube have a higher heat transfer capacity.
Materials standard
Copper Alloy: ASTM B75/ B359 C12200/ 44300/ 68700/ 70600/ 71500
Carbon Steel: SA179 and others
Stainless Steel: SS304, SS316/ SS316L

5. Hellicaly Spiral Crimped Fin Tube
Crimped Fins are spirally wrapped onto the base tube, without welding, but spot welded.
The steel strip can be copper, carbon steel, stainless steel.Non-ferrous tubes and fins on
either root soldered or completely tinned.
Material Standard of crimped fin tube
Both base tube and fin can be copper, carbon steel and stainless steel
Carbon Steel: A179, A192,SA210 Gr A1/C,A106 Gr B
Stainless Steel: TP304/TP304L
Copper strip also available.
Maximum working temperature: 120°C

6. Embedded G Type Fin Tube
The fin strip is wound into a machined groove and securely locked into place by back
filling with the base tube. G fin tube consists of aluminum fin strip that is mechanically
embedded into the wall of the tube. The embedding process is controlled by tooling that
first plows a groove into the tubes outside diameter, then guides the base of the fin into
the groove.
Materials
Tube: Carbon steel, Alloy steel, stainless steel and dual-phase steel
Fin: Aluminum/Copper, Al1060/1070/1100, etc
Maximum Working Temperature: 350°C

7. L fin tubes
The aluminum fin strip or the copper fin strip is folded into an L shape and spirally
wound tightly under the action of tension on the outer surface of the base tube. Tension
in the fin strip is wrapped around the tube serves to make the fin foot forcefully on the
tube, thus hold the fin firmly in place.
L Finned Tube is combined with two different materials
Core Tube: Carbon steel, stainless steel, copper
Fins: Aluminum, copper
Features:
1. Adopting winding process, high production efficiency
2. Uniform fin pitch, good heat transfer performance
3. Core tube is protected from air corrosion by base of fin
Maximum Working Temperature: 150°C

8. LL Fin Tube
LL fin tube is produced in same way as the 'L' type finned tube but has a wider fin base
which is overlapped during the winding process, thereby giving excellent corrosion
resistance.
Maximum working temperature: 170°
Materials
Core Tube: Carbon steel, stainless steel, copper
Fins: Aluminum, copper

9. KL fin tube, also called kurling finned tube
Before continuous winding on the surface of steel tube, the outer surface of base tube
should be rolled out. After winding, the fin foot is knurled into corresponding knurling on
the base tube therefore enhancing the bond between fin and tube. Comparing with L
type fin and LL type fin, it has better heat transfer.
Materials
Core Tube: Carbon steel, stainless steel, copper
Fins: Aluminum, copper
Maximum working temperature: 250°

10. U tube & U bend/S Type Fin Tube
NOTE:The finned tube with bending type is based on customer's request.
We have a set of U bent equipment in different radius.

11. Package Information
All tubes are well packed in plastic cap and with corrosion resistant plastic film.
Packed in strong wooden plywood box with steel frame. Or in Strong Wooden Case.

12. Our company is also specialized in supplying various of copper pipes and seamless tube
which are widely used in petroleum, natural gas, electronic, chemical power, fire and other
industrial areas, and enjoying great popularity both at domestic and abroad.
Tube Grade:ASTM B111, C1100,C12200, C44300, C68700, C70600, C71500, CuNi90/10,
CuNi70/30,etc.
Model number:C12200, C44300, C68700
