Galvanized steel pipe is made based on black welded pipe and dipped into zinc liquid then it gets a layer of zinc coating. Hot dipped galvanized tube is with heavy zinc coating which makes the GI pipes anti-corrosion with longer service life. Galvanized steel has hot galvanized and electro-galvanized two types, hot dip galvanized has depth thickness, with coating uniformity, strong adhesion, long service life, and other advantages.

This chart is normal require, the special products standard including different thickness level and other requirement, under this circumstance in this products not conflict with other products, can add thickness zinc require and other
Hot-dipped galvanized steel pipe also called galvanized iron pipe. Hot dip galvanized pipe and two kinds of galvanized, hot dip galvanized zinc layer thickness, coating uniformity, strong adhesion and long service life. Electric galvanized the cost is low, the surface is not very smooth, its corrosion resistance than galvanized pipe.
Hot dipped galvanized steel pipe is made in the molten metal and iron substrate reaction and produce alloy layer. So that the substrate and coating combination of both. 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 or ammonium chloride and zinc chloride mixed aqueous solution tank cleaning, and then sent to the hot dip plating tank. Hot dip galvanized steel pipe with uniform coating, strong adhesion, long service life. Most of the northern process using galvanized with direct volume tube zinc supplementation.
Hot dip galvanized steel pipes are widely used in construction, machinery, coal, chemical, electric power, railway vehicles, automotive industry, roads, Bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and manufacturing industry.
