Hot-dip galvanized steel pipe forms a zinc-iron alloy layer through the reaction of molten metal and iron matrix, which firmly combines the steel pipe matrix and the coating. The process includes pickling to remove surface iron oxide, ammonium chloride or zinc chloride solution cleaning, and hot-dip galvanizing to ensure that the steel pipe has a uniform coating, excellent adhesion and excellent corrosion resistance.
During the hot-dip galvanizing process, complex physical and chemical reactions occur between the steel pipe matrix and the molten zinc liquid, forming a dense zinc-iron alloy layer that is integrated with the outer pure zinc layer and the steel pipe matrix. This structure significantly enhances the corrosion resistance of the steel pipe and extends the service life of the product.
Hot-dip galvanized steel pipes not only have a smooth and uniform coating, but also maintain stable performance for a long time in harsh environments. They are an ideal choice for construction, transmission pipelines, agricultural irrigation and other fields.
