Hangzhou Fin Tube Company Limited (HZFT in short), established in 2006, is a rapid growing
enterprise which integrates product design, technology development,
production and marketing. In the past decade, HZFT has been
optimizing the technology of integral finned tube making us one of
the leading fin tube manufacturers at the same level of Wieland and
Wolverine. With the dedicating development, the market has spread
from domestic at the beginning to the entire world, especially in
North America, Australia and European countries like Germany,
United Kingdom, etc. HZFT has important terminal clients such as
HANGYANG GROUP, KAISHANG GROUP, Beijing Huahai Zhongyi(HHZY)
Industrial Furnaces Co., Ltd., Shangdong Huacheng Sino-German
Transmission Equipment Co., Ltd., Pentair, Raypak, etc.
After 10 years’ development, the product lines have almost covered
all the types of finned tubes based on extruding process. The
highest cooper or copper nickel fin reaches 10-12mm, aluminum fin
15-16mm. Meanwhile, laser welded fin tube, which has the similar
structure of extruded type, has been developed most recently in a
project together with our Germany cooperative. We can weld
8-12meter fin material at a height of 7-10mm smoothly in moving and
rolling process, which not only enriches the range of our products,
but also makes us one of the two in the entire world who masters
this technology.
The fin tubes available with us covers Integrated Finned Tube of
Copper (C10200, C12000, C12200), Cupronickel (C70600), Aluminum
(1060) and Aluminum Alloy (AISI6063), Bimetallic Finned Tube such
as Copper - Aluminum, Copper Alloy - Aluminum, Steel – Aluminum,
Stainless Steel – Aluminum, Laser Welded Fin Tube using Stainless
Steel and Titanium.
Concerning the integral finned tube, 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. On the other hand it shows
several unique features such as enhanced physical structure,
resistance to vibration, anti-corrosion ability, and long service
life, etc.
The interior surface of finned tube can be plain or undulated or
grooved according to customers’ request on different heat exchange
efficiency. Besides, the shape of finned tubes can not only be in
straight, but also after soft annealing in Omega shapes, coils, or
customized shapes catering to customers’ needs.
The laser welded fin tube, although obtained by laser welding
technology, has the structure more or less the same as the integral
type, which mean it shares similar advantage. The more significant
is that it makes much harder materials like Stainless Steel and
Titanium possible in this structure.
The finned tube HZFT providing can be used in heating (gas-fired
boilers, condensing boilers, water boilers, industrial boilers,
flue gas condensers, solar systems), in mechanical and automotive
engineering (oil coolers, mine coolers, air coolers for diesel
engines), in chemical engineering (gas coolers and heater, process
cooler), in power plants (air cooler, cooling tower), and in
nuclear engineering (uranium enrichment plants).
On the huge tide of energy-saving and emission-reduction, HZFT is
prepared for leapfrog development around the corner.
