Laser Welded Finned Tube is a Finned Tube product with relatively mature and Stable process, which has good advantages:
1. The thickness of base tube can be 0.8-1.mm, and the thickness of fin can be 0.3-1.mm, saving material cost.
2. High Penetration Rate can prevent gap corrosion, prolong service life and reduce heat transfer resistance.
3. Different materials can be used for processing.
4. It is easy for secondary processing, and can directly coil and bend pipes.
5. Small welding heat affected zone and small metallographic change make it possible to process small diameter Finned Tubes.
Laser Welded Finned Tubes are mainly used for civil wall hanging and industrial boilers in the process of use. Foreign technologies are mainly used for operation. Its main advantages are that the contact thermal resistance is zero, the whole equipment is welded at high frequency, the winging rate is large, the weight is light, the assembled Heat Exchanger is compact, the energy efficiency is high, and the emission requirements are met.
When laser welded finned tubes are manufactured, there are many kinds of finned tubes in China. If high-frequency welding finned tubes are mainly used during operation, it has more advantages in product quality and production automation than inlaying, brazing and other methods.Two Laser Welded Finned Tube
However, because the root of high-frequency welded finned tubes is difficult to penetrate and there are wrinkles at the root, there are many shortcomings in the heat exchange efficiency and preventing gray accumulation of high-frequency welded finned tubes. In view of the above reasons, there are policies for energy conservation and emission reduction.
Benefits of using laser to weld finned tubes
1. The thickness of the base tube can be 0.8-1.5mm, and the thickness of the pin in operation can be 0.3-1mm. Compared with other process costs during operation, the material cost can be greatly reduced.
2. The laser welded finned tube has a high welding joint ratio, which can prevent the corrosion in the working time gap, effectively extend the service life and reduce the heat conduction resistance.
3. When laser welding Fin Tube breaks through the material limit, other materials shall be used for processing.
4. The laser welded finned tube is easy to be processed for the second time, and the coil and elbow can be directly processed.
5. The welding heat affected zone is small and the metallographic change is small, so it is allowed to process small diameter finned tubes.
Rematerials of heat exchange tubes and condensation tubes shall have heat transfer performance, corrosion resistance, corrosion resistance, wear resistance, strong strength, strong plasticity and easy processing.
Finned tube heat exchangers for coal mines Industrial finned tube radiators have excellent heating performance, and can maintain a constant indoor temperature in large-area workshops and increase indoor vertical temperature. Industrial finned tube radiators usually use two heat transfer media, steam or heat transfer oil, and the heating temperature of these two media is higher than that of hot water. The service life of industrial finned tube radiators in workshops is generally 30 years. If people maintain them correctly and well during use, their service life can be extended to 50 years. Finned tube radiators have a long service life, are safe, reliable and excellent in use, and are the main reasons why many people choose it. Steel finned tube radiators for workshops are used in workshops, mainly using convection to circulate heat. Convection heat dissipation is a relatively good heat dissipation method among radiator series equipment. The steel finned tube radiator for the workshop has a large heat dissipation capacity. While meeting the heat demand of large-scale workshops, it can also extend the service life of the radiator with excellent pressure bearing performance and good anti-corrosion performance.
Finned Tube heat exchangers for coal mines The reliable heat dissipation of finned tube radiators is also related to the strict process standards in the production process. In fact, the production method of finned tubes is relatively simple, but the requirements to be met are higher. A radiator with a reasonable structure and a reliable process is the basis and prerequisite for its long-term and stable heating. The finned tube radiator in the workshop has good heat dissipation performance and excellent pressure bearing performance. The finned tube welded by steel pipes can have a pressure bearing capacity of about 20kg. In a large-area workshop, such a large load-bearing capacity is enough to meet The needs of the factory building, and therefore finned tube radiators are more and more widely used in the workshop. There are many reasons for the excellent cooling efficiency of finned tube radiators. The structural parameters of the radiator and the external environment will affect the reliability of the radiator.

Finned Tube Heat Exchanger adopts the method of adding finned tube heat exchanger, which greatly improves the heat emission of radiator fins and further improves the role of heat emission of radiator fins. The finned tube heat exchanger is welded with low-carbon environment-friendly steel pipes, which is durable and emits heat for a long time. Our inspection and maintenance during use are still helpful to the service life of radiator fins.
application
Finned tubes are widely used in industries such as electric power and chemical industry. Many spiral heat exchange surfaces or threaded tubes can be regarded as finned tubes. It has a significant effect on expanding the heat transfer area and promoting turbulent flow, and has a great effect on single convective heat transfer and phase change convective heat transfer. The structure of finned tube heat exchanger is basically the same as that of general shell and tube heat exchanger. Just use finned tubes instead of bare tubes as the heat transfer surface. Finned tube heat exchangers are also commonly used to heat or cool gas outside the tube, and steam or water passes through the tube, such as air coolers, boiler economizers, radiators, etc.
Finned tubes are made of a wide range of materials, such as Stainless steel, carbon steel, titanium-copper alloy, etc., and the industrial corrosion resistance is greatly improved.
