Overview
Welded helical spiral serrated finned tubes are a type of heat exchanger tube designed to enhance heat transfer efficiency. These tubes are commonly used in applications where efficient heat exchange is crucial, such as in boilers, air coolers, and other industrial heat exchangers. Let's break down the key components and features of welded helical spiral serrated finned tubes:
Tube Material:
The main tube is typically made of materials such as carbon steel, stainless steel, or other alloys, depending on the specific requirements of the application.
Fins:
The fins are spiral and serrated, which means they are helically wound around the outer surface of the main tube, forming a continuous spiral pattern. The serrations add turbulence to the air or gas flow, improving heat transfer.
Welding Process:
The fins are welded to the outer surface of the main tube. Welding ensures a strong and durable bond between the tube and the fins, allowing for efficient heat transfer.
Helical Configuration:
The helical configuration of the fins provides a larger surface area for heat exchange compared to straight fins. This increased surface area enhances heat transfer efficiency.
Serrated Design:
The serrated edges on the fins create turbulence in the fluid or gas flowing over them. This turbulence disrupts the boundary layer and promotes better heat transfer between the tube surface and the fluid or gas.
Heat Transfer Efficiency:
The combination of helical fins and serrated edges improves heat transfer efficiency by preventing the formation of a stagnant boundary layer on the fin surface. This design is especially effective in applications where high-efficiency heat exchange is required.
Description
HFW Serrated Finned Tubes is short for High Frequency Welded Helical Spiral Serrated Finned Tubes .
High frequency welding spiral fin tube is a new kind of heat transfer material which has the feature of wearing resistance and high efficient. And it is a kind of high efficiency and energy saving heat transfer element. Helical serrated finned tubse, serrated fins cut from metal strip and then helically wound around the tubes. Others are same as high frequency welded solid finned Tubes Pipes. 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 .

It adopts high frequency welding spiral technology, the national patent technology with high frequency power supplies as the heat source to heat the steel strip, steel pipe at the same time, yo make its welded together as a whole. This technology has the characteristics as high in thermal efficiency, large heat dissipation area, long service life, range adaptation temperature, high pressure, etc.
The advantages of high frequency welding spiral fin tube
1. The simple and economic installation The maximum length of high frequency welding spiral finned tube can reach 6 meters, that reduces the join points, making the installation more economic, efficient, and also reduces the leakage probability of joints.
2. Easy maintenance After installation, high frequency welding spiral fin tube needs no longer to be maintained.
3. High efficiency The heat dissipation area of high frequency welding spiral fin tube is more than 8 times of the light tube. The internal is smooth, so the internal flow resistance is small.
4. Long service life Fin and pipes with high mechanical strength, so the tensile strength is more than 200 mpa. Both inside and outside of the tube are all made of hot dip galvanized processing. Weldable fin material: carbon steel, stainless steel, alloy steel, corrosion resistant steel.
Manufacturing process
The fin strip is welded continuously and spirally wound onto a polished bare tube. And the tube and fins are bonded together by using high frequency resistance welding technique.
