Laser welded finned tubes
Our company has accumulated many years of high frequency welding
finned tube, square finned tube, Mosaic finned tube, rolled
composite steel and aluminum finned tube experience.
Cb laser welding of spiral finned tube is used in civil, industrial
boilers, etc., using German technology, domestic just started, but
has a history of more than a decade in Europe, advantage is that
the contact thermal resistance is zero, and high frequency welding
compared with wing than the big, light weight, the assembly of the
characteristics of compact heat exchanger volume, more energy
conservation and environmental protection, meet the national
discharge requirements.
Laser welding finned Tube materials such as stainless steel,
titanium, copper, carbon steel, etc
Domestic finned tube type is various, mainly high frequency welding
finned tube, though it is compared with Mosaic, brazing methods, in
terms of product quality and production automation is more
advanced, but because of the high frequency welding finned tube
roots to factors such as penetration and the roots have a fold,
lead to the high frequency welding finned tube in deposited in the
thermal efficiency and the convenient also has many shortcomings.
In view of the above reasons and in response to the national policy
on energy conservation and emission reduction.
Laser welded finned tube is the most advanced technology products,
it has irreplaceable advantages
1: The thickness of the base tube can be 0.4~ 0.8mm, and the
thickness of the fin can be 0.**0.8mm, which greatly saves the
material cost compared with other processes.
2: High penetration rate, can prevent clearance corrosion, prolong
service life, reduce heat transfer resistance.
3: Break through the material limit, can use different materials
for processing.
4: Easy for secondary processing, direct coil and elbow.
5: The welding heat affected area is small, and the metallographic
changes are small, making it possible to process the small diameter
finned tube.
Heat exchange pipe and condensing pipe material, should have
excellent heat transfer performance, but also should have good
corrosion resistance, erosion resistance, abrasion resistance, but
also should have good strength and stiffness and plasticity, easy
to process and manufacture
