Copper finned tubes using the form of the base tube covered with aluminum tube(the base tube can be carbon steel, stainless steel, copper) through machine extrusion, forming a tube fin, the fin base and the tube outer wall is close fitting, this fin tubing control can make finned tubes with high heat transfer coefficient and heat transfer performance.

Finned Tubes manufacturing process
|
Pipe line——compressing or rolling——strip peeling——washing——pressure test——blast blowing——packaging.
The cold machining process of fins provides excellent mechanical resistance , fins are strong and have strong resistance to atmospheric corrosion, etc. The pressure required to extrude the fin from the aluminum sleeve creates an excellent “pressure bond” between the two materials. In addition, the aluminum finned material completely surrounds the metal of the tube, so there is no risk of electrical corrosion at the fin root (between the tube and the fin). All of these advantages ensure the most stable performance over time of all other fin types.

Make the craft:
steel tube polishing-tooth punching on steel strip-Solid rolling on steel trip-High frequency welding-Hydrostatic pressure test, chamfering, polishing-Quality inspection -Packaging
Produce method:extruded & serrated
Application:
air cooler, fired heater, heat exchanger, marine boiler, economizer, power plant boiler, HRSG boiler, waste heat recovery unit, air heater etc
Characteristic:1.Anti-corrosion2.Anti-wear3.Lower contact resistance 4.Higher Stability
Specifications
1). Add the heat exchange area and reduce the number of tubes, also increase the fume flow section area to reduce the fume speed and abrasion.
2). H type fin tube can be made to double H type fin tube, high rigidness to fit long tube row.
3). H type fin economizer arranged in line to make the space into many small zones, averaged air flow to reduce the abrasion.
4). With straight channel to gain the best ash-blowing effect.
5). The compact structure to reduce the weight and reduce the manufacturing cost.
