There are many types of finned tubes, and new varieties are constantly emerging. Generally, it can be classified according to the following aspects:

1. Classified by processing technology

1), rolled finned tube (extruded fin tube);

2), welded finned tubes (high frequency welded finned tubes, submerged arc welded finned tubes);

3), Roll forming finned tube;

4), suit forming finned tube;

5), cast finned tube;

6), Tension winding finned tube;

7), insert tube.

Classified by fin shape

1), square finned tube (Square finned tube);

2), circular finned tube;

3), spiral finned tube (spiral finned tube);

4), Longitudinal Finned Tube

5), corrugated finned tube;

6), Helical Serrated Finned Tubes (Helical Serrated Finned Tubes);

7), needle finned tube;

8), the overall plate finned tube (plate fin);

9), inner finned tube (inner finned tube). etc.

3. According to whether the fin material of the finned tube is the same as that of the base tube, it can be divided into:

1), single metal finned tube

2), bimetal composite finned tube

Single metal finned tubes are classified by material

1), copper finned tube;

2), aluminum finned tube;

3), carbon steel finned tube;

4), stainless steel finned tube;

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

Classification by purpose

1) Finned tubes for air conditioning;

2), finned tubes for air cooling;

3) Boiler: Finned tubes for water wall, economizer and air preheater respectively;

4) Finned tubes for industrial waste heat recovery;

5), other special-purpose finned tubes; etc.
