The use of galvanized steel pipes, galvanized pipes, galvanized pipes, the kind of iron pipe used in gas and heating is also galvanized pipe. The galvanized pipe is used as a water pipe. After a few years, a large amount of rust is generated in the pipe. Not only polluting sanitary ware.
Classification of galvanized steel pipes: Cold galvanized pipes and hot -dip galvanized pipes.
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, clean it through ammonium chloride, zinc chloride water solution, ammonium chloride, and zinc chloride mixed aquatic solution groove, and then send it to Hot immersion groove.
Thermally galvanized has 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.
