Stainless Steel Laser Welding Finned Tube Evaporator Coil

Stainless Steel Laser Welding Finned Tube Evaporator Coil

Laser welded finned tubes for heat exchanger

The offer of Centre of Innovative Laser Technologies includes laser welded finned tubes. This is the first such implementation worldwide. Manufacture of tubes takes place on two automated positions integrated with line for anticorrosive protection and tubes packaging after welding.

Finned tubes made by laser technology are characterized by a continuous weld with full penetration, even face of weld and proper shape. The implemented laser welding technology allowed to obtain high quality of offered products while increasing productivity by 600%. Laser welded finned tubes offered by Datang Fin Tube meet the requirements of PN EN 12952 pressure regulations and German Law TRD 201. The developed technology is classified in accordance with the requirements of PN EN ISO 15614-11 norm.

Laser Welded Finned Tubes

In addition to the manufacturing of high-frecuency finned tubes, Datang Fin Tube offers its customers the manufacturing of finned tubes by laser welding for increased efficiency and higher quality. This laser welding production line was developed by our engineers combining both our large experience manufacturing extended surface and the most modern laser technology available in the market.

In the compromise of offering to our clients the best possible product with the higher performance for its function, Cangzhou Datang Steel Pipe Co., Ltd. has the possibility of manufacturing finned tubes by laser welding for increased efficiency and higher quality.

This line was developed by our engineers combining both our large experience manufacturing extended surface and the most modern laser technology available in the market.

The fins (solid or serrated) are helically wound and continuously welded to the tube by a fully automatic laser finning machine. This new laser finning process produces a perfect fin-to-tube bond with lower heat input and improved efficiency in heat flow and resistance to corrosion.

Advantages of Finned Tubes Welded by Laser

Highest quality product
Wider range of products in both geometry and materials
Price saving
Highest Quality Product
The perfect bond between fin and tube improves efficiency in heat transfer and resistance to corrosion resulting in a clean weld fin to tube joint and fully straight fins (no corrugation).

New Material Combinations And Range Of Production

Our Laser Finning Process allows a wider dimensional range of tube and fin combinations. Feasible height, thickness and pitch of fins go way beyond any conventional finning process.

In addition, an increased range of material combinations of both tube and fin (steel, aluminum, copper, titanium) offers new advantages and alternatives to the industry.

Price Saving

Lower energy consumption, reduced cost of consumables and increased efficiency of the process allow us to offer very competitive prices.
