ASTM A179/ASME SA179+ AL1060 Spiral Extruded L Type Finned Tube For Heat Exchanger
In L Type Fin Tube or also known as ‘L’ Foot Fin Tube the finning is done by wrapping around the Fin stock spirally around the base tube. This is as reason also known as spirally wound Fin Tube. The base of the fin stock is Shaped in to and ‘L’ shape which gives a base for the fin to stand on firmly. Also the ‘L’ shape provides a certain protection against the atmospheric corrosion.
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
