ASTM **6L Seamless Tube and Aluminum Composite Fin Tube
Â
The extruded fin is manufactured by compressing an aluminum bloom, or sleeve, onto the parent tube. The bloom is exposed to extremely high pressures which essentially "grows" the fins into the final fin profile. Therefore the fin and the tube are integrated and inseparable, which avoids the heat resistance between fin and tube, and optimizes heat exchange efficiency. Under this technology, there are two major types of finned tubes available with us, single metal tubes (also called monometallic fin tube) and Bimetallic tube (composited extruded fin tube) . The former uses Copper, Aluminum, and Copper Nickel alone. The later has a core tube on the inside made of harder material. In this case, the outer tube is rolled onto the core tube in order to provide for a tight bond and good thermal contact between the two tubes.
Fabrication Process
For composite finned tube, we need to pipe line——compressing or rolling——strip peeling——washing——pressure test——blast blowing——packaging.
Finned
tube is composited with iron-aluminum or copper-aluminum tube
rolling out the fin, which feathers are tightness, small heat
resistance, good heat transfer performance, high strength, small
flow losses, strong corrosion resistant performance, not easy to
deformation and a long working lifetime in cold and hot condition,
etc.
Overall
rolling fin is smooth and has no burr, so it is easy to clean. It
is easy to make the fin surface wet and cooled with water when
makes it cold during heating air-conditioning engineering. In the
situation with drying, heating and other heat exchanging, its
surface is handles by anodizing, which with beautiful color and
luster, and can effectively prevent surface
corrosion.
Aluminum rolling
finned tube is rolling as a whole by the aluminum tube, which has
the feather that no contact thermal resistance, high strength,
thermal shock and mechanical shock, good thermal performance, and
considerable expansion heat transfer surface. The heat exchanger
with this kind of finned tube is ahead of the string or around
the plate ones.
