Each batch of pipes is sampled and tested, and records are kept as a quality guarantee for the final product.

Laser Welded Finned Tube Product Description:

^{1. Laser welding process}

^{2. Higher heat transfer ability comparing to HF welding and Wrapped Fin Tube}

^{3. 99%-100% fully welded, without bubbles and space between fins and tube}

^{4. Save cost and assembling space due to higher efficiency}

^{Laser Welding Fin Tube Manufacturing Process:}

^{Laser welding is a high intensity laser beam to the metal surface, through the interaction of laser and metal, metal absorption laser into heat to make the metal melt after the formation of cooling crystallization welding.}
