High frequency welding finned tube Function
High frequency Welded Finned Tube is a type of finned tube, which is mainly welded by high frequency welding and is a new type of excellent heat dissipation element. The high frequency welding finned tube is welded with high frequency current, the welding method is reliable and excellent, the welding seam is small, and the surface of the radiator is more solid as well as beautiful.
High frequency welded finned tube is a heat sink element often used in finned tube radiators. Welding high-frequency welded finned tube on the base tube of the radiator improves the heat transfer coefficient of the heat exchanger side of the radiator and enhances the heat dissipation effect of the radiator, and the excellent heat dissipation effect makes the finned tube more and more popular.
The high frequency welding finned tube is welded with high frequency current, which can increase the compactness of the radiator and improve the safety of the high frequency welding finned tube radiator in the operation process. The high-frequency welding process is an improved and upgraded process on the basic welding process, which is also a more excellent welding process.
The more excellent welding process adopted for high-frequency welded Finned Tubes, the faster the welding speed and the narrower the weld seam, the more beautiful the appearance of the radiator. High-frequency welded finned tube has a simple and generous appearance, mainly in silver and gray, and can be suitable for a variety of styles of decoration, which is widely used in the field.
High frequency welded spiral finned tube is one of the most widely used spiral finned tubes, and is now widely used in power, metallurgy, waste heat recovery in cement industry and petrochemical industry.
High frequency welded finned tubes are highly adaptable and widely used, and have been widely used in a variety of fields such as industry and agriculture. High-frequency welded finned tubes are easy to operate, and users can operate them flexibly and simply to achieve the basic purpose of raising indoor temperature and providing comfort to people in the room.
High frequency welding spiral 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 the outer surface of the steel pipe heating, until the plastic state or melting, in the winding steel strip under a certain pressure to complete the welding. This high frequency welding is actually a solid-phase welding. Compared with inlay, brazing (or overall hot-dip galvanizing), it is more advanced in terms of product quality (high welding rate of fins, up to 95%), productivity and automation.

Advantages of high-frequency welded finned tubes
1. The installation is simple and economical. The length of high-frequency welding spiral finned tube can reach 6m, reducing the connection points, making the installation economical and fast, and reducing the probability of water leakage at the connection.
2. The maintenance is simple. After the installation of high-frequency welding spiral finned tube, the maintenance is basically unnecessary.
3. High efficiency. High frequency welding of spiral finned tube is the full contact welding between fins and steel pipes. The heat dissipation area is more than 8 times that of smooth tube. The internal is smooth and the internal water flow resistance is small.
4. Long service life, high mechanical strength of the combination of fins and pipes, and tensile strength of more than 200Mpa. The inside and outside of the pipes are all hot-dip galvanized.
