Finned Tubes are widely used in industries such as power and chemical industry, and 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, whether it is a single convective heat transfer or a phase change convective heat transfer. The structure of the Finned Tube Heat Exchanger is basically the same as that of the general shell and tube Heat Exchanger. Just use the Finned Tube instead of the light tube as the heat transfer surface. Finned tube heat exchangers are also often used to heat or cool the gas outside the tube, and steam or water is passed through the tube, such as air coolers, boiler economizers, radiators, etc.Laser Welded Fin Tube Discount
The range of materials for Finned Tubes is very wide, including Stainless steel, carbon steel, titanium-copper alloy, etc., and the degree of corrosion resistance has greatly increased in industries. Laser Welded Spiral Finned Tube is a new, wear-resistant and efficient heat exchange material in the fin tube welding industry. The temperature range is wide, the pressure is high, and it meets the national energy-saving and environmental protection emission standards. Widely used in waste heat recovery, petrochemical, power station boilers, economizers, passenger cars, industrial and civil building heating, refrigeration systems and other industries.
MCWAY has been focusing on the development and research of integral laser-welded Finned Tubes and single-layer and double-layer spiral coils. Now it has been applied in various fields such as boilers, chemicals, wall-hung boilers, ships, waste heat power generation, and home decoration. The surface is used most as a heating surface in the boiler industry. It is environmentally friendly, energy-saving and efficient. Laser Welded Finned Tubes are currently the most advanced products with irreplaceable advantages.
The heat exchanger is the key equipment of the thermal system. The tube-fin heat exchanger is a heat exchanger structure with high technical content and complicated production process. The cold and hot fluids are cross-flowed and exchanged between the walls. The main body of the tube is phase change heat transfer. The tubes are generally arranged in a serpentine shape with multiple tubes. The fins are divided into single, double or multi-row structures. This kind of heat exchanger is widely used in petrochemical, aviation, vehicles, power machinery, air separation, cryogenic, atomic energy, aerospace and other industrial fields. For example, superheaters, economizers, air preheaters, condensers, deaerators, feed water heaters, cooling towers, etc. in boiler thermal systems; hot blast stoves, air or gas preheaters, Waste heat boilers, etc.; evaporators, condensers, regenerators, etc. in refrigeration and low temperature systems; heating and cooling equipment widely used in the petrochemical industry, sugar liquid evaporators and pulp evaporators in the sugar and paper industries, These are numerous examples of applications for heat exchangers.
Next, we will talk about the five characteristics of Laser Welding Of Spiral Finned Tubes:
1: The thickness of the base tube can be 0.8-1.5 mm, and the thickness of the fins can be 0.3-1 mm, which greatly saves the material cost compared with other processes.
2: High Penetration Rate, which can prevent crevice corrosion, prolong service life and reduce heat transfer resistance.
3: Breaking through material limitations, different materials can be used for processing.
4: It is easy to carry out secondary processing, and can directly perform coiling and bending.
5: The welding heat-affected zone is small and the metallographic change is small, which makes it possible to process small-diameter finned tubes.

In terms of quality control:
1, Use CCD monitoring system in the production process to monitor the welding area in the whole process.
2, First article approval, use the metallographic analysis system to obtain the welding status, and continue production after ensuring the product quality is qualified.
3. Select high-quality, high-standard materials, start from the source, and ensure that the product quality is qualified.
4: Breaking through material limitations, different materials can be used for processing.
5: It is easy for secondary processing, and can be directly coiled and bent.
6: The welding heat-affected zone is small, and the metallographic change is small, which makes it possible to process small-diameter finned tubes.（Laser Welded Finned Tubes Discount）

Frequently Asked Questions (FAQ) about laser welding 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 heat between the fluid inside the tube and the fluid outside the tube.
2. How are Finned Tubes manufactured?
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 seam. Fins and tubes can be welded in different combinations of materials.
Weldable steel-aluminum finned tubes are one of the most widely used spiral finned tubes at present, and are widely used in electric power, metallurgy, cement industry, preheat recovery and petrochemical industries. In induction high-frequency welding, the high-frequency current generates an induced current in the workpiece through the coupling effect of the external induction coil of the workpiece. High-frequency welding is a stronger welding method, and the equipment should be used according to the equipment. High productivity, welding speed up to 30m/min.
