Galvanized steel pipe produce:
Hot dip galvanized steel pipe with pickling, first to remove iron oxide on the surface of
the steel tube, after acid cleaning, by ammonium chloride or zinc chloride or ammonium
chloride and zinc chloride mixed aqueous solution tank cleaning, and then sent to the
hot dip plating tank. Hot dipped galvanized zinc layer thickness, coating uniformity,
strong adhesion, long service life, etc. Steel substrate with molten electrolyte solution in
complex physical and chemical reaction, the formation of corrosion resistance of the
structure compact zinc alloy layer. Pure zinc layer, alloy layer and steel substrate fused
together .erw / lsaw spiral welded steel high quality galvanized pipe prices and
manufacturers
