High Frequency Welded Spiral Finned Aluminium Finned Tubes

High Frequency Welded Spiral Finned Aluminium Finned Tubes

High frequency welded spiral finned tube is a new type, wear-resistant and efficient heat exchange material. It is a high-efficiency and 

energy-saving heat exchange element. It adopts patented technology, uses high-frequency welding production process, takes 

high-frequency power supply as the heat source, heats the steel strip and steel pipe at the same time, and makes them fuse and 

weld together. It has the advantages of high heat exchange efficiency, high heat dissipation area, long service life, wide temperature 

range High pressure bearing characteristics. It is widely used in waste heat recovery, including chemical industry, power station 

boiler, economizer, passenger car, heating, refrigeration, pharmaceutical drying, wood drying, grain drying system and other industries.

 

Advantages of high frequency welding spiral finned tube

 

1. The installation is simple and economical. The large length of high-frequency welded spiral finned tube can reach more than 20 meters, 

and there is no connection point, which makes the installation more economical and fast, and reduces the probability of water leakage at the connection.

 

2. The maintenance is simple. After the installation of high-frequency welded spiral finned tube, there is basically no maintenance.

 

3. High efficiency, high-frequency welding spiral finned tube is full contact welding between fins and steel pipe, the heat dissipation area 

is more than 8 times that of smooth tube, the interior is smoother and the internal water flow resistance is small.

 

4. Long service life, high mechanical strength of the combination of fins and pipes, tensile strength of more than 200MPa, and hot-dip 

galvanizing treatment is adopted inside and outside the pipe.

 

Weldable fin material: carbon steel, corrosion resistant steel, stainless steel, alloy steel.

 

Weldable fin form: continuous, open tooth

 

Application of high frequency welded spiral finned tube

 

High frequency welded spiral finned tube is an efficient heat transfer element. Its heat transfer area is several times to dozens of

 times that of the smooth tube, which can strengthen heat transfer, reduce flow resistance and reduce metal consumption, 

so as to improve the economy and operation reliability of the heat exchange equipment. At present, high frequency welded 

spiral finned tubes have been widely used in chemical industry, electric power, metallurgy, petrochemical, boiler, building materials, 

light textile, environmental protection, drying, medicine and other fields.
