Delivery of laser-welded finned tubes

Another batch of laser-welded finned tubes on its way to our customer.

This order consists of 60 tubes of 4" in 310S and 321H stainless steel and length between 4 and 5 meters, and stainless steel fins in 304.

Laser-welding has greater precision and a cleaner finish. Another advantage is that it allows us to work with more combinations of materials (titanium, aluminum, copper, etc.) and the price is usually more competitive than high-frequency welding.

Finally, it consumes less energy during manufacturing, which results in a more environmentally-respectful technology.

If you are considering buying finned tubes do not hesitate to ask us for more information about this technique.

Delfin Tubes - Fabrication

Delfin Tubes has received support from the European Union, through the European Regional Development Fund (FEDER) and the Principality of Asturias, through IDEPA, for the realization of an R & D Project that allowed the development of a new Technique for the production of welded tubes by laser welding, and the subsequent surface treatment thereof. This project allows Delfin Tubes to offer to the market an improved product in terms of thermal efficiency and resistance to corrosion, thanks to the reduction of the fin pitch, the use of new materials and the application of innovative coatings. In short, offering new advantages and alternatives to the industry thanks to the use of state-of-the-art laser technology, which takes this product to higher levels of quality than any existing manufacturing process.
