Jinghua Steel Pipe Co., Ltd. Liaocheng a variety of customized hot galvanized seamless steel tubes, cold galvanized seamless steel tubes, fine drawing galvanized seamless steel tubes, galvanized precision tubes, color coated steel, Jinzhou galvanized seamless steel tubes, galvanized steel and hot-dip galvanizing method galvanized into two categories. HDG has wet, dry, lead, zinc, oxidation reduction method, the process shown in FIG. The main difference between the different methods of hot-dip galvanized steel pickling after cleaning, the method used to improve the activation of galvanized pipe surface quality. Production is now mainly dry method and redox method, which features table. Galvanized zinc coating surface is very smooth and dense, uniform organization; has good mechanical properties and corrosion resistance; zinc consumption 60% to 75% lower than the hot-dip galvanizing. Galvanized technically some complexity, but the single plating, hot galvanized seamless steel tubes, various internal and external surface coating thickness sided coating, and thin-walled tube galvanized mused shall use this method. Jinghua Steel Pipe Co., Ltd. Liaocheng custom: galvanized seamless hot-dip galvanized steel galvanized steel galvanized seamless steel fire - galvanized steel pipe plant in Liaocheng hot galvanized thin-walled seamless steel pipe thick-walled seamless steel galvanized, Small diameter galvanized seamless steel pipe, large diameter seamless galvanized. Galvanized seamless implementation of standards 1.GB/T13912-2002 metal cover layer, layer of galvanized steel products technical requirements. 2.GB/T1839-92 quality steel products galvanizing layer test method .3.GB2694-81 transmission line tower manufacturing technology requirements. 4.GB3091-82 low pressure fluid galvanized welded steel pipe.
