Recommended Industrial Laser Welded Finned Tubes
Laser Welded Finned Tubes are used in civil wall-hung boilers and industrial boilers, etc., using German technology. It has just emerged in China, but it has a history of more than ten years in Europe. The characteristics of large ratio, light weight, and compact volume of the assembled Heat Exchanger are more energy-saving and environmentally friendly, and meet the national emission requirements. The Chinese name is laser welding Finned Tube , the foreign name is Laser welding finned tube. There are many types of finned tubes, mainly High Frequency Welded Finned Tubes. Although it is more advanced in terms of product quality and production automation compared with methods such as inlaying and brazing,Recommended Industrial Laser Welded Finned Tube but due to the High Frequency Welding Finned Tubes The root is difficult to penetrate and the root has folds and other factors, resulting in many deficiencies in the heat exchange efficiency and the convenience of anti-dust accumulation of the High Frequency Welded Finned Tube.
The Finned Tube Heat Exchanger adopts the method of adding laser welded finned tubes, which greatly improves the heat exchange efficiency, Strong Corrosion Resistance, longer service life, wider temperature range, high pressure, and conforms to the national Energy-saving and environmental protection emission standards and other characteristics.
Recommended Industrial Laser Welded Finned Tubes.Finned Tube heat exchangers are indispensable machines and equipment in the overall heat transfer in industrial manufacturing. It is widely used in heat exchanger industries in petroleum refining, chemical industry, medicine, food, power plants, new energy, boilers, nuclear power and other fields. In recent years, in view of the development trend of new technology application and new energy development, improving the performance of heat exchangers has been paid more and more attention by the industrial field.

In order to improve heat Exchange Efficiency, Fins are usually added to the surface of heat exchange tubes to increase the outer surface area (or inner surface area) of heat exchange tubes, so as to achieve the purpose of improving heat exchange efficiency. Such heat exchange tubes are called fins. Sheet tube. What are the classifications of Finned Tubes? Let's find out together.
Finned tubes are divided into square finned tubes, spiral finned tubes, longitudinally finned tubes, spiral serrated finned tubes, and inner finned tubes according to shape and structure;
Finned Tubes are divided into: single metal finned tubes, bimetallic composite finned tubes;
Finned Tubes are divided into different processing techniques: rolling finned tubes, welded Finned Tubes, rolling formed finned tubes, and suit formed finned tubes.
We recommend laser-welded finned tubes for industrial use. Laser-welded composite finned tubes have a certain ability to prevent dust accumulation. In the concept of treating more, the use of finned tubes is a fusion of emotions, which is effective It carries a lot of different skills in use, and it is also an effective way to use it.
Laser welded finned tubes are a relatively Stable product
Laser Welded Finned Tube is a relatively mature and stable finned tube product with good advantages:
1. The thickness of the base tube of the laser-welded finned tube can be 0.5-1.mm, and the thickness of the fin can be 0.5-1.mm, saving material costs.
2. High permeability can prevent crevice corrosion, longer life and reduce heat transfer resistance.
3. Different materials can be used for processing.
4. Laser welded finned tubes are easy for secondary processing, and can directly crimp and bend pipes.
5. The heat-affected zone of welding is small, the metallographic change is small, and small-diameter finned tubes can be processed.
Frequently Asked Questions (FAQ) about Laser Welded Finned Tubes:
1. What is the use of Finned Tubes?
Finned tubes are the main components of heat exchangers. They are a series of tubes to which fins have been added on the outside to increase the contact area with the fluid outside to exchange heat as well as between the fluid inside the tube and the fluid outside the tube.
2. How are Finned Tubes made?
Fully automatic laser welding machine imported from Germany, 100% welding between fins and tubes, no need to use filler material, no impurities on the weld. Fins and tubes can be welded with different material combinations.
3. What are the characteristics of Laser Welded Finned Tubes?
· Finned Tubes can be easily bent and coiled
· Small heat affected zone
· The material will not deform
· Only slight microstructural changes in tubes and fins
· High heat utilization to form seams
Increased safety due to avoidance of crevice corrosion due to high weld integrity between tube and fins
· The weld seam is free of impurities, since laser welding is performed under a protective atmosphere
4. What is finned tube welding?
In the finned tube welding process, a rolled steel strip is continuously welded in a helical pattern on the outside diameter of the tube. The welds produced in this process are true forged, blacksmith welds. This type of weld consists of fusion between two parts of the parent metal without the introduction of filler material.
Selection and acceptance of laser welded Finned Tubes
The fan top finned tube is applied to the light heat sink, which is made of copper sensitive alloy. Its elastic function is to provide the resultant force for the matching of the heat sink and the module case. This structure is simple to manufacture and use, but has low fin efficiency. Therefore, fan top devices are applied to milliwatt transistors. Finned tubes can be designed according to different shapes, such as uniform rectangular straight ribs, triangular straight ribs, trapezoidal straight ribs and concave parabolic straight ribs.
No matter which type of laser-welded finned tube you choose, you should strictly check its surface quality and internal quality. In general, the requirements for its surface quality include that the lath is well processed, the surface quality is uniform, and the coating is not allowed to fall off or not cover; the cladding should be tightly bonded to the core alloy, and there should be no gaps or gaps between them. Cracks after multiple bends are not allowed.
