Greenhouse finned tube radiators, radiator fins, Huayi radiator

Brazed finned tube method because of its high cost, another way, will the good strip wrapped around the tube into the tank within an overall zinc galvanizing instead. Although the use of hot-dip galvanizing bath is not necessarily the overall well infiltrated small gap between the fins and pipes, but on the outer surface of the fin and the outer surface of the pipe has formed a complete galvanized layer. With the overall hot dip galvanized finned tubes, because of restrictions by the galvanizing layer thickness (thickness galvanized all-aluminum radiator fins, zinc layer is firmly poor radiator fins, easy off), plus zinc not all within the liquid penetrate the gap, so the fins and steel combination was still not high. In addition, the heat transfer coefficient than steel zinc is small (about 78% of steel), and therefore low heat transfer capability. Zinc in acid and alkali, sulfide vulnerable to corrosion finned tube radiator sales, so the radiator fins material unsuitable for galvanized spiral finned tube air preheater production (waste heat recovery boiler flue gas). Processing in two steps brazing finned tubes brazed spiral finned tube were. First, the strip plane perpendicular to the axis of the tube by spiral wound around the outer surface of the tube, and the ends of the strip welded on the pipe is fixed, and then to eliminate the gap at the contact strip and pipe, by soldering method The steel and steel pipe welded together. Greenhouse finned tube radiators, radiator fins, Huayi radiator by radiator plant Qingzhou City Huayi.
