Stainless Steel TP347 with 11Cr Studded Tube , Pin Tube , High Frequency Welded Fin Tube
高频焊接翅片管 also called solid type fin tube,use steel or stainless steel strip directly welded to tube surface by HFW.Can improving heat transfer efficiency much more than bare tube.Due to the tight welding of the fins to the base tube, these finned tubes are often used in vibrating conditions.Fin type have Serrated fin and flat fin.
HFW Fin Tube / Solid Finned Tubes are manufactured by helically wrapping continuous fin strip on tube. HF Resistance Welding Usually Employs Frequency Of 400 kHz. The fin wound around the tube And Continuous weld. The fin strip is wounded spirally onto the tube and welded continuously with a high frequency electrical process to the base tube along the spiral root. The fin strip held under tension and confined laterally as it is formed around the tube, thereby ensuring that the strip is in forceful contact with the base tube surface. A continuous weld is applied at the point where the fin strip first begins to bend around the tube diameter, using the gas metal arc welding process.
对于给定的管子或管道尺寸,可通过指定适当的翅片高度、翅片厚度和/或每米长度的翅片数量,获得单位长度管子所需的传热表面积。
HFW 实心翅片管
这种焊接钢制翅片管结构可用于任何实际的热交换器应用,尤其适用于高温高压应用。这种结构的重要特点是效率高,在任何温度和压力条件下都能有效地将翅片与管子结合在一起,并能承受翅片侧的高温。
通过高频电阻焊接将连续的螺旋鳍片连接到基管上,以实现高效、热可靠的结合。
