lord Fin Tube-Stainless L Type Finnned Tube

L-shaped and double L-shaped finned tubes: the most advanced numerical control L-shaped finned tube machine in China is used to keep the bonding force of the tubes in the best state through digital control. The trapezoidal section formed by rolling is consistent with the distribution of heat flow density. On the basis of saving materials, the thermal efficiency is greatly improved, and the contact thermal resistance of the tandem finned tubes caused by the inability to eliminate the tube gap is eliminated.

L Type finned tube is a kind of efficient heat exchange component and advanced energy-saving product widely used at present, which has the characteristics of high processing efficiency, chip free processing and low cost. Typical is ASTM A213 TP304 L Type Fin Tube. The heat transfer area of spiral finned heat pipe wound with L-shaped finned tube is several to dozens of times that of smooth tube, and the heat transfer efficiency is more than twice that of smooth tube.
