Economy and Energy Saving
The high-fin tube is used to advantage when gases are to be heated
or cooled or when a process stream is to be air-cooled. High-fin
tubes come in a wide variety of fin heights, thickness, and
spacings, giving values of Ao/Ai up to 25. For corrosion
protection, a mechanically bonded liner tube may be used inside the
finned tube. The liner can be made of corrosion-resistant alloy,
while the outer tube and fins are made of a high conductivity metal
such as copper or aluminum to improve heat transfer.
One major application of high-finned tubes is in air-cooled heat
exchangers. Atmospheric air, like all low pressure gases, gives a
very low heat transfer coefficient at normal velocities. By
contrast, the tube-side fluid, usually a liquid to be sensibly
cooled or a vapor to be condensed may have a coefficient up to 100
times higher, or even more. Therefore, high-finned tubes are used
in these exchangers to reduce to overall size of exchanger

Company and Service
LIFEBG INDUSTRY GROUP CO., LIMITED
Suzhou Titan Metal Material Co., Ltd. Is a subsidiary company of
Lifeng Industry Group.
Lifeng Industry Group Co., Limited is a high-technology,
engineering group in materials technology, forming, machining and
Lifeng Material Technology are divided into three areas:
Big Diameter Titanium Seamless Pipe-the market leader in China, size range from 88.9 to 219.1mm(3 to 8
inch.) outside diameter. More than 70% seamless pipes(OD from 133
to 219.1mm) in China are produced in our plant.
Stainless Steel & Nickel Alloy Tube & Pipe-the leading producer in China, size range from 6 to 609.6mm(1/4 to
24 inch.) out side diameter. Materials includes stainless steel,
duplex steel and nickel alloys.
Finned Tube-the leading producer in China, our main products include Extruded,
L, LL, KL, G(Embedded) and High Frequency Welded Finned Tubes etc.
Lifeng Material Forming-U bending tube and coil tube/pipe are our main products supplied
to customers in different fabrication areas.
Lifeng Material Machining-With advanced machining and drilling facilities, has enabled us to
be the leading manufacturer of pressure vessel and boiler parts
like tubesheet, baffle, ring and flanges in China.
Lifeng Material Welding-We can weld shell, tube bundles, heat exchangers etc. Our welding
methods inclide submerged arc automatic welding, gas shielded
semi-automatic welding, argon arc welding and shielded metal arc
welding. The weldable materials are carbon steel, alloy steel,
stainless steel and the non-ferrous metals such as copper,
aluminum, nickel alloy and titanium.
Lifeng focuses on continuous investments in research and
development, coupled with highly effective rigorous ISO 9001:2008
quality management system, enable us to produce and supply the high
quality above products to various industries-petrochemical
industry, power station desulfurization, aerospace, ship, machinery
and communication electronics etc.
1) Q: Can you send the sample to us for free before we place order?
A: Our products are mostly customized, that’s to say, we make the
sample according to the 2D/ 3D drawings from you. It will take time
and resources of our company, so we will charge you for the sample,
once you confirm without questions, we will put it into mass
production. And we will give you a discount on the basis of the
quantity of your order.
2) Q: Do you have titanium alloy in stock?
A: Yes, but just the normal specification finned tube. Most of our
products are customized.
3) Q: Why does it take at least 4 weeks to finish the mold?
A: After we get the 2D/ 3D drawings from you, our engineer will
analyze the drawings, to see whether it’s feasible. Once there is
any questions, we will feedback to you and give our suggestions if
necessary. And after you confirm without questions, we will sent to
our Mold Department for production.
4) Q: How long will it take for the production?
A: Once receipt the deposit from you, we will start the following
process: Making the mold, Making wax models, Making the shell,
Dewaxing, Roasting, Alloy casting, Getting the semi-finished
product, polishing , detection and so on. After finish, they need
time to check the products, if found any possible defect parts,
they will return to the production until every part is 100%
approved. Therefore, it will take about 25-35 days to finish the
first batch. And it just need 20-30 days to finish the second,
third, fourth…… batches.
5) Q: What’s the payment term of your company?
A: Before shipment by T/T or against copy of B/L.
