The difference between Pre-galvanized pipe and Hot Dipped galvanized pipe
1, hot-dip zinc steel pipe structure: hot galvanized pipe is the molten metal and iron matrix reaction to produce alloy layer, so that the combination of the substrate and the coating. The steel pipe is acid-washed, in order to remove the iron oxide surface of the steel pipe, pickled, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed water tank cleaning, and then into the hot dip bath in. Hot galvanized with uniform coating, strong adhesion, long life and other advantages. Hot-dip galvanized steel pipe matrix and molten bath complex physical and chemical reactions, the formation of corrosion-resistant structure of a close zinc alloy layer. Alloy layer and pure zinc layer, steel pipe body integration. So its strong corrosion resistance.
2, Pre galvanized with tube structure: galvanized pipe to produce hot galvanized pipe production process has been adjusted. The acidity of the strip is carried out in order to remove the iron oxide from the surface of the strip. After pickling, it is washed with ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed water tank, and then cleaned Into the hot dip bath. And then air-dried, and then made into a tube. With a uniform coating, bright, very little zinc, than the cost of producing hot galvanized pipe is low. Its corrosion resistance than hot galvanized pipe slightly worse!China Pre Galvanized Round Tube
