G-Type finned tubes are known as embedded fin tubes where g means grooved. They are formed by twisting a fin strip made of copper or aluminium into a machined groove and back-filling to secure the lock. Base tube material is filled. The G-type fin tube is strong as compared to other tubes. Hence, it is widely used where high-temperature heat transfer is required.

G Type Embedded Finned Tube is that the fin strip is tension wound and placed in the groove cut into the tube with appr, 0.4mm
groove depth, then the bottom of the fin is guided into the groove and backfilled with base tube Firmly, finally lock the fins in
place by rolling the grooves enclosed in the bottom of the fins. The maximum operating temperature of G Type Embedded Finned Tube
can reach 400°C.

2. Copper.
3. SteelQuality Control for G Type Fin Tube
Inspection and Tests Performed
Chemical Composition inspection,
Mechanical Properties Test(Tensile Strength, Yield Strength, Elongation, Flaring, Flattening, Hardness, Impact Test),
Surface and Dimension Test,
No-destructive Test,
Hydrostatic Test.Delivery condition:
Tube ends are square cut, free burrs, internally dried and air blown clean, externally coated with varnish at both ends of G-Fin
Embedded Finned Tube.
Acceptance Criteria
API Standard 661 (Air-Cooled Heat Exchangers for General Refinery Service) or Delivery Conditions (TDC).
Features of G Type Finned Tube for Heat Exchanger
1. High heat transfer performance and small contact thermal resistance.
2. The contact area between the fin and the tube is large, and the fit is tight and reliable.
3. Good resistance to atmospheric corrosion and stable long-term use
4. Can be used for a long time at high temperature
Application of G Type Fin Tube for Heat Exchanger
●Petroleum, chemical and petrochemical industries
●Natural gas treatment
●Steel industry: blast furnace and converter system
Power generation: exhaust gas from steam turbine condenses, condensate water contact circulation cooling condensate, fossil and
nuclear power plants
● Air conditioning (Freon, ammonia, propane)
●Waste incineration equipment
●Compressor cooler, etc.

Considered as one of the most important aspects of any gas to gas or gas to liquid type of heat-exchanger, finned tubes are compact units of vigorous and damage-resistant construction.
The outside surface of fin tubes is covered with small fins. The role of these fins is to act as a transfer process and filter. The heat transfer is generally from inside to the outside and reverse. The rate of heat transfer by a particular type of fin tube can depend upon:
Temperature difference between the fluids/gas
Heat transfer between the fluids and the walls of the tubes
The exposed surface
There are various types of finned tubes that finned tube manufacturers produce. And the type required for a particular process depends on the process equipment unit.
