Product Description

 

 

 

Hot dip galvanized pipe is the molten metal and iron substrate reaction and produce alloy layer, so that the substrate and coating combination of both Is hot dip galvanized steel pipes to pickling, in order to remove iron oxide on the surface of the steel tube after acid cleaning, by ammonium chloride or zinc chloride or ammonium chloride and zinc chloride mixed aqueous solution tank cleaning, and then sent to the hot dip plating tank Hot dip galvanizing has the advantages of uniform coating, strong adhesion,long service life and so on. Complex physical and chemical reactions occur between the steel tube matrix and the molten plating solution, forming a tightly corrosion-resistant zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer steel tube matrix, so its corrosion resistance is strong.
