The main difference between galvanized pipe and galvanized strip pipe

 Galvanized Hose:

     1 Color Galvanized tube A little green, 2 Weight: 6 meters long has 5.5 kg (corrosion resistance is slightly poor, the use of specific heat galvanized steel pipe life short, low price economy).

     Galvanized strip tube white shiny and reflective, very few snowflakes, both ends of the mouth clean zinc-free tumor.

     Hot-Dip Galvanized steel Pipe:

     1 Color Hot Dip galvanized tube a bit whitish,

     2 Weight: 6 meters long has 6.5 kg (strong corrosion resistance, long service life, slightly higher price); Hot galvanized steel pipe Snow White but not shiny not reflective, the surface of many snowflakes, both ends of the mouth has zinc tumor (condensed-like zinc) Hot-Dip Galvanized steel pipe (hot-dipped zinc galvanized pipe) is to make molten metal and iron-matrix reaction to produce alloy layer, so that the substrate and the coating of the two combined. The supply of hot galvanized steel pipe is first the steel pipe pickling, in order to remove iron oxide on the surface of the steel tube, after pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed water solution trough cleaning, and then into the hot-dip bath.

     Hot-Dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The hot-dip galvanized steel tube has a complex physical and chemical reaction with molten plating solution, which forms a close zinc-iron alloy layer with corrosion-resistant structure. The alloy layer blends with the pure zinc layer and the steel tube matrix.

     Therefore, its corrosion resistance is strong.
