Product Description

Product Details

HFW Serrated Finned Tubes is short for High Frequency Welded Helical Spiral Serrated Finned Tubes.
Helical serrated finned tubes, serrated fins cut from a metal strip and then helically wound around the tubes.
 
The important features of this configuration are Efficiency, effective bond of fins to tubes under all conditions of temperature and pressure, and ability to withstand high fin side temperatures. This serrated fin configuration is even better to withstand the fin fouling if that is a problem in the application. This gives better heat transfer properties compared to solid fins.
 
Base Tube Details: Tubes Diameter Range: 15.88 mm to 219 mm; Tubes Thickness Range: 1.651 mm to 16mm;
Tube Material: Carbon Steel Seamless Tubes, Stainless Steel, Carbon Alloy Steel, Corten Steel, Duplex Stainless Steel, Super Duplex Stainless Steel S32750, Inconel Alloy, High Chrome High Nickle Incoloy alloy, CK 20 material, and some other material.
 
Fin Details: Fins Thickness: Min. 0.8 mm to Max. 4 mm; Fins Height: Min 0.25´´ (6.35 mm) To Max 1.5´´ (38 mm); Fin Density: Min 43 Fins per Meter to Max. 287 Fins per Meter;
Material: Carbon Steel, Stainless Steel, Alloy Steel, Corten steel, Duplex Steel, and Incoloy Alloy.

High frequency welding Solid finned tube: 
Hfw Helical Spiral Serrated Fin Finned Tubes Used for Heat Recovery Steam Generator, Petrochemical, Boiler Plants and Heat Exchangers
 
 
The fins are manufactured by Spirally Winding the fin around the Base Tube and Pipe. During the winding the fin is Continuously Welded by High Frequency welding giving the Most robust bond between the the Fin and the Tube.
 
This type of Fin Tube is used specifically where the application involves a lot of Mechanical Stresses like continuous vibrations etc.
 
The welding bond between the Tube and The Fin also ensures that almost perfect heat Transfer Efficiency is achieved. Also it can give the highest operating temperature ranges.
 
These Fin Tubes find application in RADIATORS, AIR PREHEATERS, WASTE HEAT RECOVERY SYSTEMS, & BOILER FIN TUBES etc and are preferred in Industries like Power Plants, Chemical Industries, Steel Plants, and Chiller Plants etc.
 
 
Mechanical Resistance: Excellent (Hence can be frequently cleaned with high pressure jets unlike other fin tubes. Thereby reducing down time and increasing overall life)
 
Corrosion Protection: Moderate
 
Temperature Range: Up to Maximum 500 Deg C

The steel fin, that may be solid or serrated, is helically wound and continuously welded to the tube by high frequency electric resistance welding. This produces an homogeneous, clean and continuous fin-totube bond with no additional weld material, for a very efficient heat flow and resistance to corrosion.
 
Tube bending:
Our finning machines are equipped with online single or duplex cold bending equipment that can manipulate both ends of tubes in a single operation, thus ensuring exact alignment of the ends. Our bending machines are capable of bending both bare or finned tubes with diameters from 31 mm to 76 mm.
 
Corrosion protection:
If required, the external surfaces of finned tubes can be treated with a protective coating. Our engineers are always ready to assist you with design considerations to meet your specific product needs.
 
Both solid and serrated fin tube is used for Heat recovery steam generator, Petrochemical, Boiler Plants, Economizer, Gas cooler and Heat exchangers in a wide range of applications.
Solid fin tube is recommened for contaminated gas streams where oil, coal, wood or other high fouling fuels are used. Serrated fin tube is primarily used in clean streams.

We offers different finned tubes: tension wound finned tubes, embedded finned tubes and extruded finned tubes.
 
Tension wound finned tubes are formed by winding a strip made of aluminium or copper around the tube under tension. The strip winding technology provides different types of fins: L-Fin, LL-Fin, KL-Fin.
 
 
Embedded fins (G-Fins) are made by winding aluminium or copper strip into a helical groove machined on the outer surface of the tube.
Tension wound finned tubes, embedded finned tubes and extruded finned tubes are main devices for air coolers and the common application fields are:
 
Heat exchangers for power plants (electric, nuclear, thermal and geothermal power plants)
Steam condensate systems
Chemical and petrochemicalindustry
Food processing plants and refrigeration technology
Industrial (steel mills, incinerators, gas compression facilities)

EXTRUDED FIN TUBE (BIMETALLIC FIN TUBE)
EXTRUDED FINNED TUBE----This fin type is formed from a bi-metallic tube consisting of an aluminium outer tube and an inner tube of almost any material.

The Extruded Fin Tube also known as Bimetallic Fin Tube is one of the most preferred finning processes for various applications.
 
The fins are manufactured by Extruding the Fins on the Aluminum Muff Tube which is made to Fit with close tolerance over the Base Tube.
 
The Extrusion takes place on a Continuous Fin Extruder with Three Tooling rolls and extrusion takes place at high pressures in the range of 1200 psi. Because of the cold working process the Bond between the Tube and fin is flawless and hence gives excellent Heat Transfer Efficiency. At the same time the mechanical strength of the fins is also enhanced drastically.
 
These Fin Tubes find application in AIR FIN COOLERS, DRIERS, RADIATORS etc and are preferred in Industries like Food and Agriculture, Power Plants, Chemical Industries, Steel Plants, and Chiller Plants etc.
 
 
Manufacturing Process: Cold Extrusion
 
Fin To Tube Bond: Excellent
Heat Transfer Efficiency: Excellent
Mechanical Resistance: Excellent (Hence can be frequently cleaned with high pressure jets unlike other fin tubes. Thereby reducing down time and increasing overall life)
Corrosion Protection: Gives excellent corrosion protection to the base tube since it entirely covers the base tube (except bare ends).
Temperature Range: Upto Maximum 300 Deg C
