Beschrijving

The hot -dip galvanized pipe causes the melting metal to react with the iron -based body to generate the alloy
layer,which combines the substrate and the coating. The hot -dip galvanized steel pipe is used to pick up the steel pipe.
In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned in a mixed aqueous solution
groove of ammonium chloride or zinc chloride or ammonium chloride, and then sent to it Hot immersion groove.

Thermally galvanizedhas the advantages of uniform coating, strong adhesion, and long service life. The hot -dip galvanized
steel pipe matrix and melting plating fluid have complex physical and chemical reactions to form a tight zinc -iron alloy
layer with corrosion resistance. The alloy layer is integrated with the pure zinc layer and steel pipe matrix, so its corrosion
resistance is strong.

Advantages of galvanizing
The zinc coating is thicker, crystallized finely, uniformly and without pores, and has good corrosion resistance; the zinc layer
obtained by electroplating is relatively pure and corrodes slowly in acid, alkali and other mist, and can effectively protect the
fastener matrix. The zinc coating is treated with chromic acid After passivation, it forms white, colored, military green, etc.,
which are beautiful and have certain decorative properties. Since the galvanized layer has good ductility, it can be cold
punched,rolled, bent, etc. without damaging the coating.
