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.
