Product Description
Hot dip galvanized pipe is made of molten metal and iron matrix reaction to produce alloy layer, so that the matrix and coating two combination. Hot dip galvanizing is to first pickling the steel tube. In order to remove the iron oxide on the surface of the steel tube, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Complex physical and chemical reactions occur between the steel tube base and the molten bath to form a compact zinc-iron alloy layer with corrosion resistance. The alloy layer is integrated with the pure zinc layer and the steel tube matrix. Therefore, its corrosion resistance is strong.

Production Process
Features
1. Corrosion resistance: Galvanizing is an economic and effective rust prevention method that is often used. About half of the world’s zinc output is used in this process. Not only does zinc form a dense protective layer on the steel surface, but it also has a cathodic protection effect. When the zinc coating is damaged, it can still prevent the corrosion of the iron base material by cathodic protection.
2. Good cold bending and welding performance: mainly used low carbon steel grade, the requirements have good cold bending and welding performance, as well as a certain stamping performance
3. Reflectivity: It has high reflectivity, making it a barrier against heat
4, the coating toughness is strong, galvanized layer forms a special metallurgical structure, this structure can withstand mechanical damage in transport and use.
