Hot Dip Galvanized Steel Pipe
The hot dip galvanized steel pipe is the combination of substrate and galvanized plating that is the alloy coating generated from the complex physical and chemical reaction of molten metal with iron substrate. The first process for hot dip galvanization is to clean the steel tube in the pickling solvent, removing the ferric oxide from its surface. Then it will be moved into the tank with aqueous ammonia chloride or zinc chloride or their mixed aqueous solution for washing. At last, the tube will be sent to the hot dip plating tank.
The hot dip galvanized layer features high evenness, adhesive force, durability and other advantages. As the formed zinc and iron alloy layer with compact structure will combine with the pure zinc layer and the steel substrate, the hot dip galvanized layer performs well at resisting corrosion. In addition, this hot dip galvanized steel pipe is widely used as the tube for manufacturing steel structure, scaffold and furniture, processing, transporting low pressure fluid and other application.
