G embedded fin tubes (with aluminum fins)
The fin strip is wound into a mechanically produced groove and tightened by
backfilling of the base material under pressure. Groove depth 0,4 mm.

G embedded fin tubes: The fin strip is wound into a mechanically produced groove and tightened by backfilling of the base material under pressure. Groove depth 0,4 mm. Advantages: High fin stability, excellent heat transfer, high operating temperature.

MANUFACTURING PROCESS
The manufacturing tool is made up of 2 non-cutting plates set at 90° to the axis of the base tubes (pipes) (core tube).The first plate effects a groove for metal spinning. The second directs the ribbon in the groove and sets the fin foot in the groove through pressure on the metal displaced for the groove. A similar plate made of tungsten carburate allows us to manufacture. G embedded fin tubes ( fin tubes )with base tubes (pipes) (core tube) made of austenitic steel or exotic alloys.
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 unwind even when partially uprooted.

Material Combinations
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 by ourself 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.
