Elliptical Finned Tube Properties:
Elliptical pipe of reflux zone and the windward area is much smaller, effectively reduce the air side, reduce energy consumption; At the same time when the number of tube, oval tube than the circular tube structure is more compact, Heat Exchanger of smaller volume, lower cost.
Elliptical Finned Tube(Oval Steel Tube) Product Description:
This Fin Tube design utilizes an elliptical shaped tube with an efficient air foil shape to minimize air side flow resistance. These fins have improved performance characteristics compared to round tube types.
The corrosion resistance of these fins will be very high after being hot dip galvanized. These fin tubes are very compact compared to other types of fin tubes and their heat transfer efficiency is significant.
In manufacturing of these fin tubes, first the punched fins are filled automatically on elliptical tubes. Thereafter, the fins on both ends of the tubes are fixed, and fins are connected to the tubes by two different methods. The first one is by fixing the fins to the tubes by mechanical expansion of the elliptical tubes. In the second method, the tubes are dipped in melted zinc tanks. The gap between the fin and the core tube is filled completely by zinc.
The maximum working temperature in these fins is 850°C.
Elliptical Finned Tube(Oval Tube Aluminum) Manufacturing Process:
An oval seamless tube is used as the base tube, and the finned tube is spirally wound with aluminum fin tape or copper fin tape under tension and tightly wound on the outer surface of the base tube.
Elliptical Finned Tube(Oval Steel Tubing) Advantages:
It has a very long life compared to other fin tubes.
The steel fins are not sensitive to typical mechanical loads, for example hailstorm or walk on the bundles.
Hot dip galvanization provides corrosion protection.
No-flow regions are avoided by different first and second row fin pitch.
Simple cleaning using high pressure water.
Compact design with high extended surface area ratio.
Oval Copper Tubes are manufactured with a rectangular copper fin, which significantly increase the heat transfer surface area around the oval tube.
Elliptical Finned Tube(Stainless Steel Oval Tube) Applications：
Those are applied for Heat Exchanger Field , Oil refineries, Petrochemical industry, Ship-building, Power Plant Refrigeration.
• All Kind of tube material can be applied as below
• Fin spec can be changed follow with client requirement
