Lord Fin Tube--High-frequency welded spiral finned tube

High-frequency welded spiral finned tubes are precision-manufactured products produced using advanced fin tube production lines from South Korea. These tubes are designed to meet national or foreign standards and can also be manufactured according to non-standard specifications to fulfill customer requirements for mass production.

How to produce high-frequency welded spiral finned tube?

The high-frequency resistance welding technique used in the production of spiral finned tubes ensures a strong and reliable bond between the fins and the tube. This welding method is scientifically arranged to optimize the heat dissipation process in various applications, particularly in civil building heating systems that make use of natural convection mechanisms. The construction of these radiators promotes the widespread adoption of the product. 

High-frequency resistance welding series spiral finned tubes have numerous advantages, including high pressure resistance, minimal leakage, efficient heat dissipation, compact structure, and material-saving design. These characteristics make them the preferred choice for strengthening heat transfer in industrial boilers and power station boilers. They also perform exceptionally well in medium heat pipe and fuel gas boiler applications.

The high-frequency resistance welding technique employed in these spiral finned tubes relies on the high temperature generated by the high-frequency effect, causing the material to melt under external force. This results in excellent metal contact surfaces, minimal thermal contact resistance, reduced heat loss, high fin thermalization coefficient, increased heat transfer area, and improved heat transfer efficiency. The total heat transfer coefficient of these tubes is 4-8 times that of bare pipes, and the welding rate exceeds 98%. Additionally, their compact structure, small size, and material-saving advantages further contribute to their appeal.

High-frequency resistance welded spiral finned tubes find wide applications in industries such as petroleum, chemical, boiler manufacturing, metallurgy, textile, drying, cooling, and various industrial furnaces. They are used in heat exchangers, heat recovery devices, air coolers, heaters, economizers, and civil heating equipment, serving as ideal heat transfer elements.
