G Type Fin Tube
2 year ago
G Finned Tube Product Description:
(Embedded Fin)The fin strip is wound into a machined groove and securely locked into place by back filling with base tube material. This ensures that maximum heat transfer is maintained at high tube metal temperatures. Maximum operating temperature for this fin type is 450°C.
Fin material: Aluminium or copper
Tube materials: Carbon steel, Cr.-Mo. steel, stainless steel, copper, copper alloys, etc.
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:
1)Thermal
The fin/tube wall contact is constant because of the setting and makes it possible to use a wall temperature of up to 400°C.
2)Mechanical
The fin is set throughout its length and consequently does not unwind even when partially uprooted.
G Finned Tube(Copper Finned Pipe) Properties:
Core Tube: Carbon steels (ASTM A 179/ A 214, St 35.8,etc.), low-alloy steels, stainless steels, copper-nickel alloys, aluminum bronze, copper, nickel-alloys(Alloy 400, ext.),
Fins:Aluminum ASTM B209 Al 1060;ASTM B209 Al 1100, A1050, etc.
Maximum operating temperature for this fin type is 450°C.
G type embedded fin tubes machine is designed based on international advanced technologies and experience with stable and firm slotting embedding technology, pulled off force not less than 70 N, medium allowable temperature of 450 ℃, with strong resistant and heat-resistant ability, widely used in the impact of petrochemical refining air condenser.
G Finned Tube(Finned Copper Pipe) Applications：
