The welding of spiral finned tube is generally high-frequency welding. What knowledge does it contain? What can we learn from this knowledge? For those who want to understand the knowledge of finned tubes, it is also a problem to think about in the learning process. Next, let's have a good understanding, for reference only. 1. Welding principle High frequency current is used as the heat source to heat the contact surface and the area to be welded, and the upset force is applied on the outside of the fin tube to realize the solid phase welding of the contact surface. 2. Preparation before welding (1) There shall be no obvious pits on the surface of the pipe material. Sand blasting shall be carried out to remove oil, rust and other dirt. (2) The upsetting wheel shall be prepared to ensure that the clamping of the steel strip is moderately tight and uniform in the circumferential direction, and the internal parts can rotate flexibly. (3) The welding between electrode body and contact shall be firm and reliable, with smooth cooling and no leakage. 3. Welding parameters It mainly includes the tensile strength and welding rate of welded joints. The indicators of these parameters must meet the national standards, such as Q/SH.MM.25-2000.

Reasons for insufficient heating capacity of finned tube heat exchanger ① The pressure or temperature at the hot side of the pipe is too low, and the main symptom is that the temperature of the hot air at the cold side is close to the temperature at the hot side. ② The flow in the hot side of the pipe is too low, and the main symptom is that the temperature difference between the inlet and outlet of the hot side is large. ③ The flow distribution of several finned tube heat exchangers operating in parallel is uneven. The main symptom is that the inlet and outlet temperatures of each heat exchanger are inconsistent. ④ The heat transfer performance of finned tube radiator decreases with the service time. ⑤ The design effect was not achieved during the installation and commissioning of finned tube radiator, and the pipeline stroke was connected correctly, and the thermal insulation measures were ideal.

During the use of Finned Tube heat exchangers, it is very important to prevent corrosion phenomena. In order to prevent this phenomenon from happening, some corrosion-resistant materials, such as some stainless steel and aluminum alloys, are used in the production process, and their corrosion resistance is relatively strong. Effectively improve the life of the heat exchanger. However, the cost of such materials is generally relatively high, so the purchase price is relatively high. Use some corrosion inhibitors, in corrosive media, add some small amount of substances to greatly reduce the corrosion performance of the metal, and then stop, it is also some corrosion inhibitors we use. Electrochemical protection is used to protect the cathode and anode, the protection of the cathode DC power supply and the protection of the anode on the metal surface. The power consumption used in this way is very large, and the cost of use is naturally high. It is protected by anode protection method of anode protection of the equipment external power supply. The basic function of the Finned Tube heat exchanger is to transfer heat and transfer part of the heat of the hot fluid to the cold fluid. Therefore, improving the use capacity of the heat exchanger is to improve its heat transfer performance, so as to realize the heat exchanger. transfer heat. Under the premise of comprehensive consideration of fluid resistance and no fluid-induced vibration, the flow rate should be as high as possible. For fluids without phase change, the heat transfer method should be as close as possible to countercurrent flow. The purpose of this is to increase the average temperature difference and reduce heat transfer in the structure.

Advantages of using Finned Tubes Finned Tubes have several advantages: Improve heat transfer rate The fins in the Finned Tubes increase the contact surface area. This enables it to speed up the rate of heat transfer. Improve heat transfer coefficient In normal tubes, the outer surface area is about the same or slightly different than the inner surface area. In this case, the fluid with the lowest heat transfer coefficient will drive the overall heat transfer rate. Finned Tubes significantly increase surface area. This is particularly useful when the heat transfer coefficient of the fluid inside the Tube is greater than the heat transfer coefficient of the fluid outside the Tube. Finned Tube Products offers root welded Fin to tube attachments. This welding method is available on our large diameter tubes, providing a void-free fin-to-tube joint. This method of connection reduces the amount of solder used compared to the dipping process. This increases the heat transfer from the Finned Tubes. When immersed in solder, a complete insulating solder coating/film is formed over the entire Fin Tube surface. Welded Finned Tubes perform well up to 375°F.

What is a Finned Tube? Finned Tubes are elongated flat tubes made of aluminum clad carbon steel and fitted with brazed aluminum fins. These tubes are used in series for heat exchangers. The advantage they offer over normal tubes is the greater contact of the fins with the external liquid. This speeds up the heat exchange between the liquid inside the tube and the liquid outside the tube. With normal tubes, the rate of heat transfer will be much slower. Finned Tubes come in different shapes. They are available in oval, round and flat tubes. what are they used for? Finned Tubes are especially useful in the context of air heat exchangers. In an air heat exchanger, heat transfer occurs between a liquid and a gas. Finned tubes can be very helpful due to the lower thermal coefficient on the air side. Finned Tubes increase surface area, which facilitates faster heat transfer between components. Finned Tube Heat Exchanger Example Finned tube heat exchangers are used in household appliances and industrial heat exchangers. Finned tube heat exchangers are used in air conditioners and car radiators. The purpose of using Finned Tubes in an air conditioner is to cool the air that passes through it. In a car radiator, it cools the liquid in the tubes through which air passes in cross-flow. Advantages of using Finned Tubes Finned Tubes have the following advantages: Improve heat transfer rate Fins in Finned Tubes increase the contact surface area. This enables it to speed up the rate of heat transfer.

Laser Welded Finned Tube Laser welded spiral finned tube is processed by laser welding machine. Stainless steel laser welded spiral finned tube In the traditional spiral finned tube, high-frequency welding, resistance welding and other technologies are used to attach stainless steel fins to the steel pipe. Laser welding of finned tubes has its insurmountable shortcomings. If there is a large difference in thermal conductivity between the two sides of the finned tube, fins should be installed and used on the side with the smaller thermal conductivity to achieve a stable balance. Therefore, it is necessary to place the side with a small thermal conductivity outside the tube as far as possible during production to facilitate later installation operations. If the thermal conductivity on both sides is not high, only side panels can be assembled on both sides to enhance heat conduction. However, if the structure is limited, fins can be omitted, as long as both sides are balanced. In another case, if the thermal conductivity on both sides of the tube is large, there is no need to use finned tubes. Of course, in order to further improve the heat conduction, threaded pipes or corrugated pipes can be used instead of light pipes, and the effect is also very prominent.
