High frequency welded finned tube is one of the spiral finned tubes currently in use. It is a heat dissipation element that is improved by high-frequency welding for the shortcomings of string and winding fins. It can increase the heat exchange area, the economy of the equipment and operation, can strengthen the heat transfer, reduce the flow resistance, the same heat exchange can significantly reduce the volume of equipment to reduce metal consumption, thus the economy of heat exchange equipment, is increasingly used in heat exchange equipment including boilers, especially the use of low and medium temperature waste heat boiler equipment.

High-frequency welding finned tube is in the steel strip winding steel pipe at the same time, the use of high-frequency current skin effect and proximity effect, the steel strip and steel pipe outer surface heating, until the plastic state or melting, in the winding steel strip under a certain pressure to complete the welding, the steel strip welded firmly in the tube.

It is compared with inlay, brazing (or overall hot-dip galvanizing) and other methods, both in terms of product quality and productivity and degree of automation. Its metal thermal strength has reached 1.10 ~ 1.20w is now used in electric power, metallurgy, cement, construction, and petrochemical industries. Its cost performance and heat transfer efficiency and other comprehensive indicators are excellent, is the ideal product in the field of heat exchange.

High frequency welding finned tube welding

High-frequency welded finned tube heater series products are made of steel pipe and steel strip welded together. It has the characteristics of high pressure-bearing and long service life. The appearance of this high-frequency welded finned tube radiator is sprayed with a variety of amino baking paint, bright colors, beautiful appearance, small size, light weight, and easy installation.

The round wing type hot-dip galvanized radiator is specially designed for large indoor heating such as greenhouses. The product has a large heat dissipation area, light weight, small footprint, beautiful appearance, easy installation, uniform heat dissipation, easy temperature adjustment, and can be arranged and combined in indoor locations according to needs, either single pipe connection or multiple pipes connected in parallel for heating.
