the fin strip is wound into a mechanically produced groove and tightened by backfilling the base material under pressure. Groove depth appr. 0,4 mm.

Advantages: High fin stability, excellent heat transfer, and high operating temperature.

Material Combinations:

G Fin Tube Core Tube: Carbon steels, low-alloy steels, stainless steels, brass, copper, copper-nickel alloys, aluminum bronze, nickel-alloys (Alloy 400, etc.), bimetal, titanium, and others

G Fin Tube Fins: Aluminium / Copper / Steel / Galvanized Steel

Fields of Application:

the petroleum, chemical, and petrochemical industries

Natural gas treatment

the steel industry: blast furnace and converter systems

Power generation: steam turbine exhaust condensing

Contact condensing with cooling of circulating condensate

Fossil and nuclear power plants

Air conditioning (freon, ammonia, propane)

Incineration of household refuse

Compressor coolers, etc.

Manufacturing Process:

the manufacturing tool is made up of 2 non-cutting plates set at 90° to the axis of the base tube. the first plate affects 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 carburetor allows us to manufacture G-finned tubes with base tubes made of austenitic steel or exotic alloys.

Advantages:

1) G Fin Tube 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) G Fin Tube Mechanical

the fin is set throughout its length and consequently does not unwind even when partially uprooted.
