HFW Serrated Spiral High Frequency Welding Finned Tube With Long Service Life
概述
TONG CHUANG Group's Welded Helical Serrated Finned Tubes are produced in the same manner as solid fin， except that before the fin strip is formed around the tube， the fin strip is cut (or “serrated”) crosswise from one edge (which will become the outer edge of the fin segments) to within 1/4″ of the other edge， leaving an uncut portion that will become a continuous base for the fin segments. The interval between cuts (which determines the segment width after the strip is formed around the tube) may be specified as either 5/32″ or 5/16″. After being cut， the fin strip is held under tension and confined laterally as it is formed around the tube， thereby ensuring forceful contact with the tube surface. As the fin strip is formed around the tube its outer (serrated) edge spreads， opening the segments like petals of a daisy. A continuous weld is applied at the point where the fin strip first begins to bend around the tube diameter using TONG CHUANG Group's unique gas metal arc welding (GMAW) process.

Advantages of high frequency welded spiral finned tubes
1. The installation is simple and economical， and the maximum length of the high-frequency welded spiral fin tube can reach 6 meters， which reduces the connection point， makes the installation more economical and fast， and reduces the probability of leakage of the connection point.
2. Simple maintenance， after the installation of high-frequency welding spiral fin tube， basic maintenance is required.
3. High efficiency， high frequency welding spiral fin tube is the finned tube and steel pipe wrapped full contact welding， the heat dissipation area is more than 8 times the light tube， the interior is more smooth， the internal water resistance is small.
4. Long service life， high mechanical strength combined with fin and pipe， tensile strength of more than 200Mpa， all pipes inside and outside are hot dip galvanized treatment.
