High Frequency Resistance Welded Spiral Fin Tube as Heat Exchanger
for Boiler Economizer
Serrated spiral high frequency welding fin tube
High frequency welding spiral fin tube is a new kind of heat
transfer material which has the feature of wearing resistance and
high efficient. And it is a kind of high efficiency and energy
saving heat transfer element.
It adopts high frequency welding spiral technology, the national
patent technology with high frequency power supplies as the heat
source to heat the steel strip, steel pipe at the same time, yo
make its welded together as a whole. This technology has the
characteristics as high in thermal efficiency, large heat
dissipation area, long service life, range adaptation temperature,
high pressure, etc.Widely used in waste heat recovery,
petrochemical industry, power plant boiler, economizer, coaches,
civil building heating, refrigerating, drying, medicine of wood
drying, food drying system and other industries.
Advantages of igh frequency welding spiral fin tube:
1. The simple and economic installation
The maximum length of high frequency welding spiral finned tube can
reach 6 meters, that reduces the join points, making the
installation more economic, efficient, and also reduces the leakage
probability of joints.
2. Easy maintenance
After installation, high frequency welding spiral fin tube needs no
longer to be maintained.
3. High efficiency
The heat dissipation area of high frequency welding spiral fin tube
is more than 8 times of the light tube.The internal is smooth, so
the internal flow resistance is small.
4. Long service life
Fin and pipes with high mechanical strength, so the tensile
strength is more than 200 mpa. Both inside and outside of the tube
are all made of hot dip galvanized processing.
Weldable fin material: carbon steel, stainless steel, alloy steel, corrosion resistant
