Hot dip galvanized steel pipe
Hot dip galvanized pipe is made of metal and molten iron alloy body reaction layer, so that it can combine the coating and the matrix.Is hot dip galvanized steel pipes to pickling, in order to remove iron oxide on the surface of the steel tube after acid cleaning, by ammonium chloride or zinc chloride solution or ammonium chloride and zinc chloride aqueous solution tank, and then into the hot dip tank.Hot dip galvanizing has a advantage of uniform coating, adhesion strong, long life etc..
Hot Dipped Galvanized Steel Pipes
Plating steel substrate and melting of the physical, chemical reaction to form complex structure, corrosion resistance of zinc alloy layer closely.Pure zinc alloy layer and layer and steel substrate.So the corrosion resistant ability.
