What is Spiral Wound Finned Tube or Crimped Fin Tube?

Spiral Wound Finned Tube or Crimped Fin Tube are spirally wrapped fins onto the base tube, without welding, but spot welded at end.

Spiral Wound Finned Tube or Crimped Fin Tube material: The fin strip can be copper, carbon steel, stainless steel, non-ferrous tubes and fins on either root soldered or completely welded.

Helical Tension Wound Finned Tubes for Air Cooler

Since the stainless steel is with high corrosion resistance, the stainless steel crimped fin tube can be widely used when the circumstance has a certain degree of corrosion or cleanliness, such as climatic industry, heating, drying and cooling. Usually applied in fin tube heat exchangers. Maximum working temperature is 180℃.

Spiral Wound Finned Tube or Crimped Fin Tube offer a higher airside turbulence and heat transfer on account of the crimping of the fins as compared to the L Type Fin Tube.

Material Standard of crimped fin tube: Both base tube and fin can be carbon steel and stainless steel

Advantages of hot dip galvanized finned tube

1. The cost of hot-dip galvanized fin tube treatment is low: the cost of hot-dip galvanizing antirust is lower than that of other paint layers;

2. The hot-dip galvanized finned tube is durable: in the suburban environment, the standard hot-dip galvanized antirust thickness can be maintained for more than 50 years without repair; in urban areas or offshore areas, the standard hot-dip galvanized antirust coating can be maintained for 20 years without repair;

3. The reliability of the hot-dip galvanized finned tube is good: the galvanizing layer and the steel are metallurgical combined and become a part of the steel surface, and the durability of the primary coating is more reliable;

4. The toughness of hot-dip galvanized fin tube coating is strong: the zinc coating forms a special metallurgical structure, which can withstand mechanical damage during transportation and use;

5. Comprehensive protection of hot-dip galvanized finned tube: every part of the plated part can be coated with zinc, even in the depression, sharp corner and hidden place can be protected by the full name;

6. Hot dip galvanized finned tube saves time and effort: the galvanizing process is faster than other coating construction methods, and can avoid the time required for painting on the construction site after installation.

High frequency welding finned tube radiator for string type and winding type fin made of the shortcomings, and improved by high frequency welding is an efficient heat radiating element of finned tube, fin tube itself is the strip thickness 0.8-1mm winding in the finned tube, and the high-frequency welding process, the welding in tablets pipe, ensure the bonding strength of tube and fin, the metal heat intensity reached 1.10 1.20w/kg degrees centigrade, widely used in boiler economizer of the finned tube air preheater and production workshop, production of residential energy-saving radiator, and heat pipe as the late winding preferred.

Spiral finned tube is an efficient heat transfer device. Its heat transfer area is several times to several times, it can strengthen heat transfer, reduce the flow resistance, reduce metal consumption, so as to improve the economic and operational reliability of heat exchange equipment. At present, the spiral finned tube has been widely used in various boilers.The structure of the spiral finned tube is shown as the figure above.
