无缝翅片管

翅片管是在外表面周围有小翅片的管子.

这些翅片充当过滤器和机制，将热量从管内材料传递到外部空间，反之亦然. 翅片管用于需要通过管壁将热量从热流体传递到较冷流体的应用.

格兰德提供各种翅片管(碳, 不锈的,铜,铝,钛,等;) 用于热交换器 (空气, 水和化学冷却)适用于石油等各种行业, 石油化, 钢, 发电等等.

Why use finned tubes?

Finned tubes are used in applications involving the transfer of heat from a hot fluid to a colder fluid through a tube wall. The rate at which such heat transfer can occur depends on three factors: (1) 两种流体之间的温差; (2) 每种流体与管壁之间的传热系数; 和 (3) 每种流体暴露的表面积. In the case of a bare (unfinned) tubes, where the outside surface area is not significantly greater than the inside surface area, 传热系数最低的流体将决定整体传热速率. When the heat transfer coefficient of the fluid inside the tube is several times larger than that of fluid outside the tube (for example steam inside and oil outside), the overall heat transfer rate can be greatly improved by increasing the outside surface of the tube. In mathematical terms, the product of heat transfer coefficient for the outside fluid multiplied by the outside surface area is made to more closely match the product of the inside fluid heat transfer coefficient multiplied by the inside surface area.

So the whole concept of finned tubes is to increase the outside surface area of the tube. As an example, a finned tube configuration of 2” (nominal, 2.375” actual) pipe with a ¾” high welded helical solid fin of 12 gauge thickness with 6 fins per inch has an outside surface area of 8.23 sq. 英尺. per linear foot; whereas the same bare pipe has an outside surface area of only .62 sq. 英尺. per linear foot. That is a 13X increase in outside surface area. See Design Information for extensive tables of surface areas and fin weights.

“The whole concept of finned tubes is to increase the outside surface area of the tube.”

“In many cases, 一根翅片管取代六个或更多裸管，小于 1/3 成本和 1/4 the volume.”

By increasing the outside surface area of the tube, the overall heat transfer rate is increased, thereby reducing the total number of tubes required for a given application. This reduces the overall equipment size and the cost of the project. In many cases, 一根翅片管取代六个或更多裸管，小于 1/3 the cost and ¼ the volume.
