Fin tube are used wherever electric power is generated or raw materials are refined and where efficient cooling is required .

Material Combinations:

Core Tube

Carbon steels,low-alloy steels,stainless steels,brass,copper,coper-nickel alloys,aluminium bronze,nickel-alloys(Alloy 400,etc),bimetal,titanium and others.

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°c to the axis of the base 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 carbure allows us to manufacture G finned tubes with base tubes 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 consequentl does not unwind even when partially uprooted.
