L Type Finned Tube for Heat Exchanger
L Type Finned Tube is a finned tube made of aluminum fin tape or copper fin tape folded into an L-shaped spiral under tension and wrapped tightly around the outer surface of the base tube. It is combined with two different materials.
The tension in the fin strips of the L Type Finned Tube wraps around the tube, causing the fin feet to press forcefully against the tube, holding the fins firmly in place.
Manufacturing Process
Fin strips (usually aluminum and copper) are folded into an L shape and wound under tension on the surface of the base tube. The feet of the fins are connected together and cover the surface of the fins.

Features of L Type Finned Tube
1. The trapezoidal section formed by the calendering of L Type Finned Tube for heat exchanger is consistent with the distribution of heat flow density, the tubes are tightly combined, and the thermal efficiency is high, which eliminates the contact heat caused by the gap between the tubes and the finned tube. resistance, the fin spacing is uniform, and the heat transfer performance is good.
2. The tube can withstand temperatures up to 150°C and there is no risk of atmospheric corrosion or thermal stress.
3. The L-type finned tube provides the contact area between the fin strip and the surface of the tube to protect the tube wall from atmospheric corrosion.
4. This L TYPE design is much more economical than LL, KL or even G-embedded types.
5. Maximum operating temperature: 230°C
