There are many types of finned tubes, and new varieties are constantly emerging. Generally, they can be categorized into the following aspects:

1. Categorized by processing technology

1) Extruded fin tube

2) Welded Finned Tubing (High-frequency Welded Finned Tubing, Submerged Arc Welded Finned Tubing)

3) Rolled fin tube

4)套装 formed fin tubes

5) Cast finned tubes

6) Tension-wound finned tubes

7) Inserted tube.

Categorized by fin shape

1) Square finned tube

2) Circular finned tube

3) Spiral finned tube

4) Vertical Fin Tubengitudinal Finned Tube）

5) Dimpled fin tubes

6) Helical Serrated Finned Tubes

7) Finned tubular heat exchangers

8) Overall plate fin tube (plate fin)

9) Inner finned tube. Etc.

3. Based on whether the fin material of the finned tube is the same as the base tube material, they can be divided into:

1) Single Metal Fin Tube

2) Double-metal composite finned tube

Single metal finned tube, categorized by material

1) Copper finned tube

2) Aluminum finned tubes

3) Carbon steel finned tube

4) Stainless Steel Finned Tube

5) Cast iron (cast steel) finned tubes; etc.

Categorized by application

1) Air conditioning finned tubes

2) Air-cooled finned tubes

3) Boiler: Finned tubes used separately for water-cooled walls, economizers, and air preheaters.

4) Finned tubes for industrial waste heat recovery

5) Special-purpose finned tubes; etc.
