High-frequency welded Helically/spiral finned tube is a new type,wear-resistant and high-efficiency heat exchange material.It is a high-efficiency and energy-saving heat exchange element. The belt and the steel pipe are heated at the same time, so that they are welded together into a whole, which has the characteristics of high heat exchange efficiency, large heat dissipation area, long service life, wide temperature range and high pressure resistance. Finned tubes are widely used in waste heat recovery, petrochemical, power plant boilers, economizers, passenger cars, industrial and civil building heating, refrigeration, medicine drying, wood drying, grain drying systems and other industries.

The advantages of high frequency welding spiral finned tube

1. The installation is simple and economical. The length of the high-frequency welded spiral finned tube can reach 6 meters, which reduces the connection points, makes the installation more economical and fast, and reduces the probability of water leakage at the connection.
2. Maintenance is simple, after the high-frequency welded spiral fin tube is installed, maintenance is basically no longer required.

3. High efficiency, high frequency welding spiral finned tube is full contact welding of fin and steel tube winding, the heat dissipation area is more than 8 times that of the light tube, the interior is smoother, and the internal water flow resistance is small.
4. Long service life, high mechanical strength combined with fins and pipes, tensile strength above 200Mpa, all inside and outside the pipe are treated with hot-dip galvanizing.

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

Application:Heater,Cooler,Condenser

With an aim to increase the heat exchanging efficiency, It’s usually to extend the surface area (or internal surface area) by adding fins onto a tube, which, through this manufacturing process, would greatly improve and upgrade the heat transferring efficiency of heating tube, it’s called Finned Tube or Fin Tubes.

But, as a element of heat exchanger, fin tubes would be working on very high temperature condition for long time. For example, the application of boilers, which is with bad ambience, high temperature, high pressure and corrossion, all require the fin tubes to be qualified with very high performance capacity as following:
1. Anti-corrossion
2. Anti-wear
3. Lower contact resistance
4. Higher stability
5. Anti-fouling ability
