High Frequency Welding Serrated Spiral Fin Tube

High frequency welded spiral Fin Tube is an efficient heat transfer element. The heat transfer area of serrated spiral fin tube is several to dozens of times of the same long bare tube.  HP spiral fin tube can enhance heat transfer, reduce flow resistance and reduce metal consumption, thus improve the heat transfer equipment economy and operational reliability. At present, high frequency welded spiral fin tube has been widely used in chemical industry, electric power, metallurgy, petrochemical, boiler, building materials, light textile, environmental protection, drying, medical and other fields.

Advantages of high frequency welding spiral fin tubes

1.Simple and economical installation  High frequency welding spiral fin tube are with zero connection point, so that the installation is more economical, fast, and reduce the probability of leakage at the joint.

2. Easy maintenance. After installation, high-frequency welded spiral fin tube doesn’t need  additional maintenance.

3. High efficiency  High frequency welding spiral fin tube is full contact welding between fin and steel tube whose heat dissipation area is more than 8 times of bare tube. In addition, the smooth internal wall reduces water flow resistance as well.

4. Long service life, Fin and pipes are combined with high mechanical strength whose tensile strength is more than 200 Mpa. Both inside and outside of the tube are treated with hot dip galvanized processing.
