Hot dip galvanized pipe

The hot-dip galvanized tube is obtained by reacting a molten metal with an iron matrix to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle the steel pipe first, in order to remove the iron oxide on the surface of the steel pipe, after pickling, it is washed by ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then fed. Hot dip plating tank. Hot-dip galvanizing has the advantages of uniform plating, strong adhesion and long service life. The steel pipe matrix and the molten plating solution undergo complex physical and chemical reactions to form a corrosion-resistant structure of a zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe base. Therefore, its corrosion resistance is strong.

1. Uniformity of galvanized layer: The steel pipe sample shall be continuously immersed in copper sulfate solution for 5 times without being red (copper plating)

2, surface quality: the surface of the galvanized steel pipe should have a complete galvanized layer, there must be no black spots and bubbles that are not plated, allowing for a rough surface and local zinc tumors.
