Product Description

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.

 

 

 

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.

Finned tube heat exchangers generally use air to cool or heat fluids such as air, water, oil or gas, or they can be used to capture or recover waste heat. These heat exchangers can used in a broad range of industries including oil & gas, power generation, marine and HVAC&R.

Finned tube heat exchangers have a wide range of applications, a few of which are:

• diesel charge air coolers;
• oil coolers;
• hydrogen coolers;
• waste heat recovery;
• driers;
• air conditioning;
• air heaters;
• steam condensers;
• generator coolers

Finned tube heat exchangers are often used in circumstances where air is the preferred medium for the cooling or heating, particularly where there is limited or poor quality water.

In a finned tube heat exchanger, heat is exchanged between a thermally efficient fluid that transports heat efficiently, such as a liquid which has some viscosity, and a fluid that does not, such as air or gas with little density. On the 'air side', the tube surface is enhanced by the addition of fins or other elements such as looped wires, designed to increase the surface area of the tube and improve its thermal performance.

Fins can range in height (high-fin to low-fin) and the fins can be either pressure connected to the outer surface of the tube or formed into the tube surface.

Depending on the intended duty and the environment in which they are to operate, finned tubes can be manufactured in numerous designs and incorporate a combination of differing materials for both the tubes and the fins. The types and combinations of tubes and fins is significant.

This often-used type of heat exchangers consists of a tube package out of straight finned tubes, which are mostly arranged, staggered in the direction of air flow. The tubes are being welded or rolled in in two opposite tube plates, the distribution of media works via the tube chambers. Those heat exchangers might also be executed with frames or casings.
