hot sale galvanized steel pipe price  

Galvanized pipe, also called galvanized steel, which has two kinds :hot galvanized and cold galvanized .hot dip galvanized having thicker galvanized than other and having a uniform coating, strong adhesion, long life and much advantages.

Hot galvanized steel pipe is molten metal and reacting the iron matrix alloy layer, so that the substrate and coating combination of both. Hot-dip galvanizing is the first steel pickling, in order to remove the steel surface of the iron oxide, after pickling, a mixed aqueous solution tank cleaning by aqueous ammonium chloride or zinc chloride or ammonium chloride and zinc chloride, and then into hot-dip plating bath. HDG has a uniform coating, strong adhesion, long life and other advantages. Most northern craft galvanized zinc with a direct hose reel process. Steel matrix and the molten bath complicated physical and chemical reactions, the formation of corrosion-resistant compact layer of zinc-iron alloy. Alloy layer and the layer of pure zinc, steel base blend, so it resistant to corrosion.

Cold galvanizing is electrogalvanizing, which has a very small galvanizing only 10-50g / m2, its own corrosion resistance have a lot of difference with hot galvanized pipe. Zinc plating layer is independent layered zinc coating and steel substrate. Zinc layer is thin, simple zinc layer attached to the steel substrate easily. Therefore, it corrosion resistance is poorer than hot galvanized.

Jawaysteel produces hot-dip steel galvanized pipes are widely used in various industrial and construction fields, we are popular among customers as we used advanced technology and have quality assurance, lower price .
