Hot Dip Galvanized Pipe Detailed Introduction

Jun 08, 2017

Hot-Dip galvanized pipe is to make the molten metal and iron-based body reaction to produce alloy layer, so that the substrate and the coating of the combination, hot galvanizing is the first steel pipe pickling, in order to remove the iron oxide on the surface of the steel pipe, after pickling, through the ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed water solution tank in the cleaning, and then into the hot dip bath, hot dip galvanized with uniform coating, strong adhesion, long service life and so on.
Hot-dip galvanized steel pipe substrate and molten plating complex physical, chemical reaction, the formation of corrosion-resistant structure of a close zinc ferroalloy layer, alloy layer and pure zinc layer, steel pipe matrix into one, so its corrosion-resistant ability.
