Laser Welded Finned Tubes
Stainless steel Laser Welded Spiral Finned Tube
In traditional spiral finned tubes, stainless steel fins are attached to steel tubes by high frequency welding, resistance welding and other techniques. Laser welding of finned tubes has its insurmountable shortcomings in the welding process.
The laser-welded spiral finned tube adopts a fully automatic welding process, which saves labor costs; secondly, the laser-welded fins are Firm and strong, and the tensile strength test is qualified; laser welding has higher efficiency advantages.
The laser welding machine is currently the most advanced laser welding equipment for spiral finned tubes. Since the welding process is fully automatic and mechanical, the scientific and technological content and quality of laser welded spiral finned tubes are superior to traditional cooling tubes.
Laser Welded Finned Tube is a new type of wear-resistant and efficient heat exchange material in the finned tube welding industry. Features. It has the characteristics of high heat exchange efficiency, large heat dissipation area, long service life, wide adaptable temperature range, high pressure bearing, and compliance with national energy saving and environmental protection emission standards.

Why use Aluminum Fins For Stainless Steel Laser Welded spiral fin tubes?
Depending on the application and operation of the heat exchange, there are various materials. The common ones are aluminum, alloy, copper, brass, nickel, titanium, stainless steel, carbon steel, etc. Among them, aluminum and alloy are the most commonly used.
The basic performance of finned tube heat transfer should have good welding ability and forming ability, high mechanical strength, good corrosion resistance and good thermal conductivity. Nonetheless, aluminum and alloys are ductile, and their tensile strength increases at lower temperatures. Fin Tube used extensively all over the world, especially for low temperature and compact heat exchange.

Generally speaking, for high-frequency welded finned tubes used in engineering projects, when the fin height is 0.8mm, the fin efficiency is about 15. When the fin height is 20mm, the fin efficiency is reduced to 0.7. Based on this, the optimal height is 15 mm. If the fin height exceeds 20mm, the fin efficiency will be poor, so it is generally not used. However, for aluminum fins on air coolers, a height of 22-25mm is always used as aluminum conducts heat much better than carbon steel.
How will the fin pitch affect the fin ratio?
Often a smaller pitch is effective in increasing the fin ratio. When considering the nature of flowing gas and ash deposits, the following factors should be kept in mind.
severe heavy ash deposits
Such as the waste gas of electric furnace and converter in steel plant and industrial pit furnace, which has high ash content. If finned tubes are used for heat exchange, a larger fin spacing is recommended. For example, if the spacing is greater than 10mm, it is necessary to increase air discharge and choose a blower.
Advantages of Laser Welded Finned Tubes:
Thin, continuous wet seam
small heat affected zone
short heating time
Only slight microstructural changes in tubes and fins
seam formation at high temperature
Fast welding speed
Laser welding is carried out in a protective atmosphere, so the weld seam is free of impurities
