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.
