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.
制造工艺
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.

L 型翅片管的特点
1.热交换器用 L 型翅片管压延形成的梯形截面符合热流密度分布,管子结合紧密,热效率高,消除了管子与翅片管间隙产生的接触热,阻力小,翅片间距均匀,传热性能好。
2.这种管子可以承受高达 150°C 的温度,并且没有大气腐蚀或热应力的风险。
3.L 型翅片管提供了翅片条与管子表面的接触面积,以保护管壁免受大气腐蚀。
4.这种 L 型设计要比 LL、KL 甚至 G 型嵌入式设计经济得多。
5.最高工作温度:230°C
