G Finned Tube Product Description:
The fin strip is wound into a mechanically produced groove and tightened by back filling of the base material under pressure.
Groove depth appr. 0.4 mm.
G Fin Tube Core Tube: Carbon steels, low-alloy steels, stainless steels, brass,copper（Copper Finned Pipe）, copper-nickel alloys, aluminium bronze（Aluminum Finned Tube）, nickel-alloys (Alloy 400, etc.), bimetallic, titanium and others
G Fin Tube Fins: Aluminium / Copper （Finned Copper Pipe）/ Steel / Galvanized Steel
G Finned Tube 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 ( Finned Aluminum Tubing )with base tubes (pipes) (core tube) made of austenitic steel or exotic alloys.
G Finned Tube Advantages:
High fin stability, excellent heat transfer, high operating temperature.
The fin/tube wall contact is constant because of the setting and makes it possible to use a wall temperature of up to 450°C.
The fin is set throughout its length and consequently does not unwind even when partially uprooted.
This kind of finned tube is one of optimum choices for having good effectiveness/cost ratio.
G Finned Tube Properties:
High performance and efficiency.
Use at high operating temperature.
Can be used for low and high temperature applications.
Dimensionally stable.
Resists high loads and shocks, both mechanically and thermally.
Fin Contact:
Mechanical bond (fin embedded in tube groove).
Maximum Tube Wall Operating Temperature:400°C.
