G Finned Tube Product Description:
Aluminum Embedded Finned Tubes consists of aluminum fin strip that is mechanically embedded into the wall of the tube. The embedding process is controlled by tooling that first plows a groove into the tubes outside diameter, then guides the base of the fin into the groove and finally locks the fin in place by rolling the groove closed on the base of the fin. This strong mechanical bond holds up to vibration and continuous thermal cycling and can withstand temperatures far greater than those for aluminum L-foot finned tubes. Typical fin spacing is 10 fins per inch of tube length — this can be varied.
G Finned Tube(Aluminum Finned Tube) Manufacturing Process:
A helical groove is formed in base tube displacing of material and fin is wound into the groove under tension, followed by backfilling of the displaced material to lock the fin root into the tube.
Fin materials: Aluminium Base
Tube materials:Any readily machinable material
G Finned Tube(Finned Aluminum Tubing) Advantages:
High fin stability, excellent heat transfer, high operating temperature.
The fin/tube wall contact is constant because of the setting and makes it possible to use a wall temperature of up to 450°C.
The fin is set throughout its length and consequently does not unwind even when partially uprooted.
This kind of finned tube is one of optimum choices for having good effectiveness/cost ratio.
