Laser Welded Finned Tube Product Description:

1. 99%-100% fully welded, with high thermal conductivity

2. Extremely strong anti-corrosion ability

3. Enhanced structure due to the welding process

4. Flexible as straight tube or bent or coiled heat exchangers

5. Low heat resistance between fins and tube

6. Strong resistance to shock and thermal expansion and contraction

7. Cost and energy saving due to long service life and high exchange rate

Laser Welding Fin Tube Manufacturing Process:

The fin strip is welded continuously and spirally wound onto a polished bare tube. And the tube and fins are bonded together by using advanced laser welding technique.

Laser Welding Fin Tube(Welded Spiral Pipe) Advantages:

1.The thickness of base tube and fin can be 0.8-1.5 mm and 0.3-1 mm respectively, which greatly saves the material cost compared with other processes.

2.High penetration rate can prevent gap corrosion, prolong service life and reduce heat transfer resistance.

3.No material restriction, different materials can be used for processing.

4.Easy for secondary processing, can be directly coiled and bent.

5.The welding heat affected zone and the metallographic change are small, which makes it possible to process the small diameter fin tube.

6.A variety of material combinations are available, titanium/ copper, titanium/titanium, carbon steel/carbon steel, stainless steel/stainless steel, stainless steel/copper, etc.

Laser Welded Finned Tube(Stainless Steel Welded Pipes) Properties:

1.Advanced technology: the product using laser welding technology, 100% penetration rate.

2.Stable quality: the equipment using full automatic production process, product quality is stable and reliable.

3.High heat efficiency: the product has smaller fin spacing and thin tubes to increase the heat transfer area and heat transfer rate.

4.It can be bent into different shapes to meet different production needs.
