G Finned Tube Product Description


Metal is merely shifted, not removed, by a helical groove 0.2-0.3 mm (0.008-0.012 in) ploughed into the outside of the base-tube wall. The displace metal is rolled back on each side of the fin to hold it in place after the aluminium fin is physically wound into the groove under strain. This is why it’s also known as an embedded finned tube. The thickness beneath the groove is the effective thickness of the base-tube wall. This kind provides great thermal and mechanical contact between the fin and the groove. Despite the fact that the base tube metal is exposed to the outside, testing conducted under server settings revealed that long-term corrosion is required before any bond failure develops. The G-type Fin Tube can withstand temperatures of up to 750 degrees Fahrenheit (450 C degree)



Aluminum Finned Tube



G Finned Tube Manufacturing Process




Fin strip is rolled in a uniform taper, helically wound into a plowed groove into the tube wall

and simultaneously backfilled (by flat rotating discs) on both sides to lock the fin to the tube.

No tube material is removed. This gives an excellent bond with high pull out loads.

Fin Material: Aluminium/Copper/Carbon Steel.

Core Tube Material: Carbon Steel/ Carbon Alloy Steel/Stainless Steel/ Nickel Alloys/Copper/Copper Alloys.
