Extruded finned tube features:
The finned tube provide by us is Extruded Type, which is different
from the ones through HF Welding and Wrapping method. The fins are
obtained by roll forming the outer surface of a soft seamless plain
tube. The technology simply squeezes the wall thickness
transforming into straight fins on the tube. So the fin and the
tube are integrated and inseparable, which avoids the heat
resistance between fin and tube, and optimizes heat exchange
efficiency. Based on this structure, the Extruded type can survive
more severe working conditions than other finned tubes. Also it, on
the other hand, shows several unique features such as enhanced
physical structure, resistance to vibration, anti-corrosion
ability, and long service life, etc.
Under this technology, there are two major types of finned tubes
available with us, Single metal tubes and Bimetallic tubes. 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.
Customized finned tube is available. The specification table is
followed below. If required, the fin tube can be made into various
forms after soft annealing process. They can be used for cooling
and heating in a large scale of conditions. For example, coils in
water heater, oil cooler in large machines, heat transfer part in
boiler and heat recovering system, air-conditioning and
refrigeration industry as condenser part or evaporator part, etc.
The material for our fin tube covers Copper(C10200, C12000,
C12200), Copper Nickel(C70600), Aluminum(1060), Aluminum alloy,
Aluminum-Steel(bimetallic), Aluminum-Stainless Steel(bimetallic),
Aluminum-Copper(bimetallic), Aluminum-Copper Nickel(bimetallic),
Copper-Copper Nickel(bimetallic).
Advantage:
1. Optimized inner to outer surface ratio
2. High heat exchange rate
3. Enhanced structure due to the roll forming process
4. Flexible as straight tube or bent or coiled heat exchangers
5. Low heat resistance between fins and tube
6. Strong resistance to shock and thermal expansion and contraction
7. Cost and energy saving due to long service life and high
exchange rate

FAQ
1. What Does Fin Tube Mean?
A fin tube is a tube that has small fins around the outside
surface. These fins act as a filter and a mechanism to transfer
heat from the material inside the tube to the outside space or vice
versa. Fin tubes are used in applications that require a transfer
of heat from a hot fluid to a colder fluid through the tube's wall.
The rate at which such heat transfer occurs depends on three
factors:
The temperature difference between the two fluids.
The heat transfer coefficient between each of the fluids and the
tube wall.
The surface area to which the fluid is exposed.
2. Where is finned tube heat exchanger used?
Finned tube heat exchangers generally use air to cool or heat
fluids such as air, water, oil or gas, or they can be used to
capture or recover waste heat. These heat exchangers can used in a
broad range of industries including oil & gas, power
generation, marine and HVAC&R.
