纵向翅片管

Product introduction:

As with welded spiral finned tubes, this welded structure can be used for virtually any heat transfer application.

The choice between longitudinal finned tube and spiral finned tube seems to depend mainly on geometric factors. 例如, some heater structures consist of finned tubes inserted into other tubes -- longitudinal finned tubes are an obvious choice for such applications. In other cases, users prefer the longitudinal finned tube installation, where the tube will be in a vertical direction - the finned direction facilitates fluid drainage on one side of the finned tube.

Longitudinal finned structures are most commonly used in shell and tube applications, such as in double-tube and multi-tube heat exchangers, where the longitudinal finned tube is telescopic in the hole of a larger tube shell. Heat is transferred between the fluid flowing through the finned tube hole and the fluid flowing through the shell hole.

The fluid flowing through the shell hole is forced to flow between the longitudinal fins. In this case, the spiral fin prevents the flow of the fluid, rather than allowing it to flow between the fins.

产品 特性:

• Improve heat transfer efficiency in efficient space.
• Reduces installation space on required heat transfer surfaces
• Reduce the cost of the equipment, and have a high operational reliability.
• The pressure drop on the side of the tube is reduced and the operation cost is reduced.
• The stiffness of steel tube is improved, and the seismic performance of steel tube is improved.
• Enhance heat transfer, reduce flow resistance and metal consumption

Manufacturing process

纵向翅片管是通过沿管的长度焊接带有电阻的翅片来生产的. 鳍片首先形成一个U形通道, 允许每个 U 形腿形成一个鳍. 将通道切割成适当的长度，然后沿管子和电阻的长度焊接到位. 通道是一对焊接的, 对立两极, 因此，指定的鳍片数量必须是四的倍数.

对于给定的管或管尺寸, 通过指定适当的翅片高度和翅片数量，可以获得每管单位长度所需的传热表面积. 翅片的最大数量取决于管子的外径 - 较大的外径管可容纳更多翅片.
