Elliptical Finned Tube Manufacturing Process:
The finning is a procedure of producing by impinging rotating discs mounted on 3 equally spaced arbours, onto and into the surface of the blank which has slipped over a mandrel.
In the finning process, most of the metal movement is radial, with some circumferential movement.
The blank tubes are stacked on the side table of the machine and the blank is loaded on to the machine mandrel as per the length of the plain required. The tube may be finned for full length without any skip on manual setting or for skips if required the auto switch may be selected. The tube with landing may be manufactured as per the requirements. After finning the tube is sawed to length and racked in finished material rack. Then all, the tubes are tested on pressure testing systems as per the clients or standards requirements. The tubes may than be forwarded for "u" bending or stress relieving if required or kept ready for dispatch.
The base tube is elliptical or oval.
Elliptical Finned Tube(Oval Steel Tube) Product Description:
Elliptical Fin Tube is an elliptical seamless tube as the base tube, which uses aluminum fin strips or copper fin strips to spirally and tightly wrap around the outer surface of the base tube under tension.Elliptical Finned Tube is a heat exchange element consisting of a base tube elliptical tube and outer fins.
Because Elliptical Finned Tube has superior performance than round finned tube, Elliptical Finned Tube is receiving attention, and Elliptical Finned Tube has been widely used in ethylene, oil refining and other industrial fields. Elliptical Finned Tube is used in heat exchange equipment as a high-efficiency heat exchange element. The flow resistance outside the tube is small and the heat exchange efficiency is high, which makes the heat exchange equipment tend to be compact, lightweight, efficient and miniaturized.
Elliptical Finned Tube(Oval Tube Aluminum) Properities:
(1) Compared with the round tube finned tube, the Elliptical Finned Tube is easier to achieve a compact arrangement, which reduces the overall volume of the entire Heat Exchanger, thereby reducing the footprint.
(2) Due to the shape characteristics of the Elliptical Finned Tube, the air-side resistance is small, and the heat transfer coefficient between the fluids increases; the thermal resistance in the tube is relatively small, which increases the heat transfer of the fluid in the tube.
(3) The heat transfer area of the Elliptical Finned Tube is larger than that of the circular tube of the same cross-sectional area, because the heat transfer periphery of the elliptical tube is relatively long under the same cross-sectional area.
(4) Rectangular steel fins are the most commonly used in Elliptical Finned Tubes, which have high strength, and the base tube is not suitable for frost cracking in winter and has a long service life.
(5) Since the Elliptical Finned Tube can be arranged more compactly, the front row tube has a greater impact on the rear row. The fin spacing of the rear row tube can be increased to reduce the flow resistance outside the tube, but the number of tube rows should not be too large.
Elliptical Finned Tube(Oval Steel Tubing) Advantages:
Elliptical tube 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(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
• Applied Temperature : 850 C (1593 F)
• This is for Air Cooled Heat Exchanger, Condenser, Air Heater in field of Oil Refinery, Petrochemical Industry, Offshore and Power plants
